In this highlight we briefly review several of our recent theoretical studies focused on how the interplay between the chemical and the van der Waals interactions determines the bonding mechanism of several chemically functionalized π-conjugated organic molecules on non-magnetic and magnetic surfaces. In particular, we focus on the issue how to tailor the strength of the interaction between suc...

Inside back cover image: Crystal structure of π-conjugated small molecules and polymers is fundamentally critical to understand the multilevel microstructures. However, determining crystal conjugated remains a significant challenge. Jian Pei coworkers build possible structures eight typical polymers, covering several widely used molecular segments in organic optoelectronics. These are modeled b...

Benzo[1,2-b:4,5-b']dithiophene (BDT) is an excellent building block for constructing π-conjugated molecules for the use in organic solar cells. In this paper, four 4,8-bis(5-alkyl-2-thienyl)benzo[1,2-b:4,5-b']dithiophene (TBDT)-containing A-π-D-π-A-type small molecules (COOP-nHT-TBDT, n = 1, 2, 3, 4), having 2-cyano-3-octyloxy-3-oxo-1-propenyl (COOP) as terminal group and regioregular oligo(3-h...

Pyrrole-based π-conjugated anion-responsive molecules bearing an anionic moiety form self-complementary dimers, which exhibit self-sorting behaviours depending on the substituted positions of anionic sites.

Organic molecules and polymers with extended π-conjugation are appealing as advanced electronic materials, and have already found practical applications in thin-film transistors, light emitting diodes, and chemical sensors. Transition metal (TM)-catalyzed cross-coupling methodologies have evolved over the past four decades into one of the most powerful and versatile methods for C-C bond formati...

Introduction The assembly of alkane-based molecular layers on metals (e.g. Au, Ag, Pt) and, to a smaller extent, on semiconductors (e.g. GaAs, Si) has been investigated in detail. Such chemistries, although potentially valuable in surface engineering and patterning, cannot facilitate charge transport on the molecular level due to their backbone saturation. On the other hand, π-conjugated system...
