Chirale π-konjugierte Nanosäulenmoleküle auf der Basis von Naphthodithiophen-Diimid zeichnen sich durch eine starre Säulenform und Fülle einzigartiger optischer chiraler Eigenschaften aus, die sie zu idealen Bausteinen für den Aufbau wichtiger supramolekularer 2D-Architekturen machen. Einzelheiten dieser Studien werden im Forschungsartikel Mathieu Linares, Hui-Jun Zhang, Jianbin Lin et al. S. 2...

We review the recent progress in the field of helically assembled π-conjugated polymers, focusing on aromatic conjugated polymers with interchain helical π-stacking that exhibit circularly polarized luminescence (CPL). In Part 1, we discuss optically active polymers with white-colored CPL and the amplification of the circular polarization through liquid crystallinity. In Part 2, we focus on the...

The elucidation of new structure–property relationships in π-conjugated molecules bearing quinoidal moieties is relevance organic electronics applications and as models doped conducting polymers.

Carbon quantum dots have been conjugated with medicinal dihydropyrimidinone molecules to formulate a multifunctional anticancer drug. Benign CQDs impart fluorescence properties, which enable the composite be used for bioimaging.

A rational synthetic strategy is developed to provide compact and simple terpyridine (terpy) mesogens that show liquid-crystallinity both as pure compounds and in organic solution (amphotropic compound). The use of a central 4-methyl-3,5-diacylaminophenyl platform equipped with two lateral aromatic rings, each bearing three appended aliphatic chains, allows connection of a 2,2':6',2''-terpyridi...

We calculate that significant quantum interference effects can be observed in elastic electron transport through acyclic molecules. Interference features are evident in the transmission characteristics calculated for cross-conjugated molecules; significantly, these effects dominate the experimentally observable conduction range. The unusual transport characteristics of these molecules are highl...

The use of conjugated polymers as active media in organic semiconductor devices demands a deep knowledge of the electronic processes involved at molecular level. Here we report the results obtained from self-consistent molecular dynamics calculations at the CNDO (Complete Neglect of Differential Overlap) level concerning intra-chain charge mobility for two well known polymers: polydiacetylene (...
