Abstract: Supramolecular chemistry has evolved from the traditional focus on thermodynamic on‐pathways to the complex study of kinetic off‐pathways, which are strongly dependent on environmental conditions. Moreover, the control over pathway complexity allows nanostructures to be obtained that are inaccessible through spontaneous thermodynamic processes. Herein, we present a family of peptide‐based π‐extended tetrathiafulvalene (exTTF) molecules that show two self‐assembly pathways leading to two distinct J‐aggregates, namely metastable (M) and thermodynamic (T), with different spectroscopic, chiroptical, and electrochemical behavior. Moreover, cryo‐transmission electron microscopy (cryo‐TEM) reveals a different morphology for both aggregates and a direct observation of the morphological transformations from tapes to twisted ribbons.

We present charge-transfer assemblies of electron accepting, pressure-synthesized carbon nanodots (pCNDs) and an electron donating porphyrin. Amidine derivatization of the porphyrin allows for hydrogen bonding interactions with the carboxyl groups on the surface of pCNDs, which drive the formation of the assembly. Upon photoexcitation, this electron donor–acceptor supramolecular construct features ultrafast charge separation, and subsequent charge recombination in 27 ps. [ABSTRACT FROM AUTHOR]

The development of synthetic methods to build complex functional systems is a central and current challenge in organic chemistry. This goal is important because supramolecular architectures of highest sophistication account for function in nature, and synthetic organic chemistry, contrary to high standards with small molecules, fails to deliver functional systems of similar complexity. In this report, we introduce a collection of fullerenes that is compatible with the construction of multicomponent charge-transfer cascades and can be placed in triple-channel architectures next to stacks of oligothiophenes and naphthalenediimides. For the creation of this collection, modern fullerene chemistry-methanofullerenes and 1,4-diarylfullerenes-is combined with classical Nierengarten-Diederich-Bingel approaches. [ABSTRACT FROM AUTHOR]

New supramolecular (metal)porphyrin/SWCNT hybrids have been synthesized through a combination of hydrogen bond and electrostatic interactions. Our experimental findings reveal through different techniques (XPS, TGA, UV-vis, Raman, and TEM) an efficient n-doping of the SWCNT from the electron donor (metal)porphyrin through the efficient and strong amidinium-carboxylate connectivity.
