Abstract

Triarylamines oxidized to radical cations can be used as stable spins sources for the design of high-spin compounds. Here, we present the synthesis of the polyarylamine-containing hexaazacyclophanes linked via meta-terphenyl bridges. Spins, created after oxidation of the polymer, can be coupled magnetically in cyclophane moieties via meta-phenyl and along the polymer chain via meta-terphenyl units. The formation of a quintet spin state was evidenced by pulsed-EPR nutation spectroscopy. Two exchange coupling constants via both couplers were determined experimentally and corresponded to J/k = 89 K in the cyclophane moiety and j/k = 17 K via meta-terphenyl. Most importantly, in this polymer, four spins can be ferromagnetically ordered via both couplers, which leads to the high spin state.

Abstract

Voltammetric and spectroelectrochemical behavior of two newly synthesized conjugated polymers, which show the same chemical constitution but different type of regioregularity, is compared. These are poly(fluorenone- alt -dioctyl bithiophene)s in which the alkylthiophene rings are either head to head (HH) or tail to tail (TT) coupled, termed PFDOBT-HH and PFDOBT-TT, respectively. Both polymers can be electrochemically p- and n-doped and show the electrochemical energy gap ( E g el ) of the order of 2 eV. In the oxidation side of the voltammogram PFDOBT-HH gives a relatively narrow anodic peak with a maximum at E = 0.78 V versus Fc/Fc + . The corresponding peak of PFDOBT-TT is much broader with the maximum shifted to slightly lower potentials ( E = 0.74 V versus Fc/Fc + ). UV–vis-NIR and Raman spectroelectrochemical studies confirm that the oxidative doping of PFDOBT-TT starts at lower potentials and indicate significant differences in the anodic oxidation in both cases. In PFDOBT-HH the doping is sequential, which means that it starts by the oxidation of the bithiophene sub-units and is completed by the oxidation of the fluorenone ones. In the case of PFDOBT-TT both sub-units are doped simultaneously.

Abstract

This report describes the study of a dimer d2+ and a linear trimer t3+ of amminium radical cations coupled by 3,4'-biphenyl spin coupling units. The synthesis of the parent diamine and triamine and their optical and electrochemical properties obtained by UV-visible and cyclic voltammetry are presented. The chemical doping of the parent diamine d and triamine t was performed quantitatively to obtain samples containing the corresponding dimer d2+ and trimer t3+ in almost pure high-spin states as evidenced by pulsed EPR nutation spectroscopy. The J coupling constants of the corresponding S = 1 and S = 3/2 spin states were measured (J/k = 135 K) and compared quantitatively to DFT calculations.

Abstract

Polyarylamine containing meta-para-para-aniline units in the main chain and meta-para-aniline units in the pendant chains was synthesized. The polymer can be oxidized to radical cations in chemical or electrochemical ways. The presence of meta-phenylenes in the polymer chemical structure allows for the ferromagnetic coupling of electronic spins, which leads to the formation of high spin states. Detailed pulsed-EPR study indicates that the S = 2 spin state was reached for the best oxidation level. Quantitative magnetization measurements reveal that the doped polymer contains mainly S = 2 spin states and a fraction of S = 3/2 spin states. The efficiency of the oxidation was determined to be 74%. To the best of our knowledge, this polymer is the first example of a linear doped polyarylamine combining such high spin states with high doping efficiency.

Abstract

Magnetic properties of a doped linear polyarylamine (PA2), whose chain includes alternating para-phenylene and meta-phenylene groups, and of two cyclic and linear model compounds (C2 and D2) were explored by pulsed-EPR nutation spectroscopy, SQUID magnetometry and DFT calculations. Stoichiometrically doped PA2 samples exhibit a pure S = 1 state (exchange coupling constant J = 18 K) with a high spin concentration (0.65) corresponding to 65% of mers bearing holes. Such properties were already observed for doped reticulated polyarylamines but are quite unusual for doped linear polyarylamines. In order to better understand the properties of PA2, model compounds C2 and D2 were also investigated: pure S = 1 spin states could also be obtained, but with higher J (respectively 57 K and 35 K) and, surprisingly, with high but still limited spin concentrations (respectively 0.77 and 0.65).

Abstract

New π-conjugated alternating copolymers containing thienylene and fluorenone units, namely poly[(5,5‴-dioctyl-[2,2′;5′,2″;5″,2‴]quaterthiophene)-alt-(2,7-fluoren-9-one)] (PQTF8), as well as its analogue without fluorenone groups (PQT8), have been synthesized. Absorption studies carried out both in solution and in thin films indicate that the presence of fluorenone chromophores in PQTF8 leads to a significant extension of the absorption spectrum in the visible range as compared to PQT8. The redox properties of both polymers, in particular their LUMO and HOMO levels, have been characterized by cyclic voltammetry and have been found suitable for potential use of these systems in organic solar cells. Finally, these materials have been tested as donor components in bulk-heterojunction-type photovoltaic cells using PCBM as an electron acceptor. We demonstrate a strong effect of the polymer's molecular weight on crucial cell parameters, such as the short-circuit current density Jsc, and therefore on the overall cell efficiency. This effect is particularly pronounced for PQTF8-based cells leading to power conversion efficiencies up to 1.5% for the highest molecular weights.

Abstract

Symmetric alkylthiophene-based mixed heterocyclic trimer and pentamer, containing central oxadiazole units, have been prepared. Because of the electron-withdrawing properties of oxadiazole, the trimer cannot be electropolymerised and undergoes an oxidative-type destruction at high potentials. In contrast, the pentamer readily polymerises, giving a short chain polymer. Both trimer and pentamer exhibit strong photoluminescence with a maximum at 399 nm (13% quantum yield) and 467 nm (46% quantum yield), respectively. The polymer resulting from the electropolymerisation of the pentamer is also luminescent with the maximum of the excitation band at 528 nm (33% quantum yield). The polymer can be oxidatively doped as demonstrated by cyclic voltammetry, showing a clear anodic peak at 0.62 V versus Ag/Ag+ and its cathodic counterpart at 0.56 V, associated with the undoping process. The significantly higher potential of the oxidative doping of the prepared mixed heterocyclic polymer, as compared to the poly(alkylthiophene) homopolymer of similar molecular weight, is caused by the presence of the oxadiazole unit, which lowers the electron density in the π-electron system of the oligothiophene subunit and makes its oxidation more difficult. The spectroelectrochemical investigation of the polymer is consistent with its voltammetric behaviour, exhibiting doping-induced bleaching of the band originating from the π-π* transition and simultaneous growth of the bipolaron bands. The observed clear and reversible spectroelectrochemical behaviour makes the developed polymer a promising candidate for applications in electrochromic devices or electrochemical sensors.

Abstract

A new solution processable, regioregular, alternate copolymer of fluorenone and dialkylbithiophene, namely poly[(5,5‘-(3,3‘-di-n-octyl-2,2‘-bithiophene))-alt-(2,7-fluoren-9-one)] (abbreviated as PDOBTF), was synthesized by three different preparation methods: chemical or electrochemical oxidation of 2,7-bis(4-octylthien-2-yl)-fluoren-9-one or polycondensation of 2,7-bis(5-bromo-4-octylthien-2-yl)-fluoren-9-one in the presence of Ni(0) reagent. Independent of the preparation method, the crude product is a mixture of high molecular weight fractions and short oligomers. It can be however easily fractionated into fractions differing in their molecular weight by sequential extractions with a series of solvents. The principal absorption band registered for the undoped polymer (λmax = 384 nm for the THF solution and 389 nm for the solid state) originates from the π−π* transition of the conjugated backbone and is blue-shifted because of the chain torsion effects caused by steric hindrance. This band is accompani...

Abstract

The synthesis and spectroelectrochemical behaviour of a new solution processible conjugated polymer, namely poly[{5,5′-(3,3′-di-n-octyl-2,2′-bithiophene)}-alt-(2,7-fluoren-9-one)] (abbreviated as PDOBTF), are described. PDOBTF can be considered as the first member of a new family of conjugated copolymers—poly(oligothiophene-alt-fluoren-9-one)s—whose properties can be tuned by changing the length of the oligothiophene segments and their regiochemistry. PDOBTF can be obtained by oxidative polymerisation of 2,7-bis(4-octylthien-2-yl)-fluoren-9-one or by condensation polymerisation of 2,7-bis(5-bromo-4-octylthien-2-yl)-fluoren-9-one using a modification of Yamamoto coupling. Both preparation methods lead to a mixture of polymeric and oligomeric species and require post-polymerisation fractionating if high molecular fractions are to be obtained. Oxidative polymerisation gives product of a higher molecular weight (Mn = 41.0 kDa, Mw/Mn = 1.81 for the highest molecular weight fraction) as compared to the one prepared by Yamamoto condensation polymerisation (Mn = 13.3 kDa, Mw/Mn = 1.45 for the highest molecular weight fraction). Electrochemical oxidation of PDOBTF in an nonaqueous electrolyte (0.1 M Bu4NBF4/acetonitrile) gives rise to an anodic peak at E = 835 mV, which can be ascribed to the p-type doping of the copolymer. The extension of the potential to E = 1500 mV results in the oxidative degradation of the copolymer and induces total loss of its electroactivity. UV-Vis-NIR and Raman spectroelectrochemical data are consistent with the oxidative doping. The latter technique enables the monitoring of the doping-induced changes in both structural sub-units of the copolymer: the bithiophene sub-unit and the fluoren-9-one one.

Abstract

This critical review discusses specific chemical and physicochemical requirements which must be met for organic compounds to be considered as promising materials for applications in organic electronics. Although emphasis is put on molecules and macromolecules suitable for fabrication of field effect transistors (FETs), a large fraction of the discussed compounds can also be applied in other organic or hybrid (organic-inorganic) electronic devices such as photodiodes, light emitting diodes, photovoltaic cells, etc. It should be of interest to chemists, physicists, material scientists and electrical engineers working in the domain of organic electronics (423 references).
