Abstract

Abstract : Molecular design for the self-assembly of molecular materials. Abstract : A centrosymmetric fused polyheteroaromatic system, namely 7-azaindolo[2, 3- h ]α-carboline, was synthesized. The pentacyclic structure includes rationally located hydrogen bond donor and hydrogen bond acceptor sites to induce its self-assembly. The molecular units associate forming an extended monodimensional arrangement that further self-organizes through π-stacking. The optical, electrochemical, X-ray diffraction, computational and electronic characterization in organic field effect transistors proves the utility of hydrogen bond-directed self-assembly as a strategy to enhance edge-to-edge interactions and orbital overlap that contribute to the charge transport properties in π-conjugated systems.
