A tetradentate ligand, 1,1,2,2-tetrakis(4-(pyridin-4-yl)phenyl)ethene (TPPE), was adopted to construct a two-dimensional coordination polymer that incorporated valence tautomerism and luminescence, and the synergistic effect arising from energy transfer from TPPE to the semiquinone moieties was experimentally and theoretically uncovered.

We report a phosphine-directed ruthenium-catalyzed C8-selective alkylation of naphthalenes with alkenes. This protocol provides straightforward access to a large library of electron-rich C8-alkyl substituent 1-naphthphosphines, which outperformed common commercial phosphines and their precursors in the Pd-catalyzed Suzuki–Miyaura coupling of aryl bromides with alkylboronic acid.

The development of molecular materials whose physical properties can be switched between different states has attracted significant attention for their potential application in sensing, information processing, spintronics, and smart actuators. Generally speaking, such functional bistability can be induced by the motion of electrons or constituted molecules in response to external stimuli. In this Feature Article, we will introduce how to manipulate the structural variations, including spin crossover, molecular reorientation, and molecular displacement, to tune the magnetic properties, optical properties, dielectric properties, and mechanical response of single-crystal materials, with a highlight of our contributions to this booming field.

An atypical homochiral spin-crossover (SCO) framework (1) constructed from mechanically interlocked 1D molecular loops was prepared. Due to the flexibility of the interlocked structure, the guest solvent molecules can be reversibly exchanged. Consequently, its SCO behavior was capable of modulating between one- and two-stepped transitions in response to acetonitrile and methanol. [ABSTRACT FROM AUTHOR]

Correction for 'Multiple correlations between spin crossover and fluorescence in a dinuclear compound' by Chun-Feng Wang et al., Chem. Commun., 2016, 52, 14322–14325, https://doi.org/10.1039/C6CC07810A. [ABSTRACT FROM AUTHOR]

A pair of novel chiral one-dimensional compounds with the general formula [Cd(NO3)2L2]·THF (where L is R- or S-2,2′-bis(methoxymethoxy)-6,6′-bis(4-pyridyl)-1,1′-binaphthyl) for the first time show circularly polarized luminescence, two-photon excited fluorescence, and second harmonic generation activity.

Multiple correlations between spin crossover and fluorescence are established in a dinuclear compound with fluorescence from d(Fe) + π(SCN) to π*(ligand) charge transfer and correlation originated from ligand to Fe(ii) energy transfer. [ABSTRACT FROM AUTHOR]

A cyano-bridged {Fe2Co2} complex shows reversible single crystal-to-single crystal transformation between diamagnetic and paramagnetic states switched specifically by losing and absorbing methanol at room temperature in the solid state. And the solvent loss form presents temperature- and pressure-induced intramolecular electron transfer behaviour. [ABSTRACT FROM AUTHOR]

A 3D 2-fold interpenetrated porous coordination polymer, [Fe(NCS)2(tppm)]·5CH3OH·2CH2Cl2 (1·sol, tppm = 4,4′,4′′,4′′′-tetrakis(4-pyridylethen-2-yl)tetraphenylmethane), was synthesized, which showed temperature, light and solvent-induced spin-crossover behaviours. [ABSTRACT FROM AUTHOR]

A metal–organic framework, [{Fe(NCS)2}3(TPB)4]·x(guest) [1·x(guest), TPB = 1,3,5-tris(4-pyridyl)benzene], shows selective gas adsorption and guest-dependent spin-crossover behaviour. [ABSTRACT FROM AUTHOR]

A 1D MoVMnIIIchain compound balanced by {Fe[HC(3,5-Me2pz)3]2}2+dications was prepared. This complex displays a typical single-chain magnet character associated with the MoVMnIIIchain and a spin crossover phenomenon arising from cationic Fe(ii) subunits. The spin crossover behavior tends to slightly affect single-chain magnetic properties at low temperature. [ABSTRACT FROM AUTHOR]

Adding a small amount of commercial GeO2into aqueous suspension significantly enhanced the photocatalytic activity of titania-based photocatalysts for the degradation of dyes. [ABSTRACT FROM AUTHOR]
