TY - JOUR AU - Schmid, Sylvia; Wunderlin, Markus; Mena-Osteritz, Elena; Bäuerle, Peter TI - Copper-Templated Formation of Dihelical Oligothiophene–Phenanthroline Assemblies SN - 2625-1825 PY - 2022 JF - Organic Materials LA - EN VL - 4 IS - 03 SP - 86 EP - 101 DA - 2022/09/15 ET - 2022/07/27 KW - oligothiophenes KW - phenanthrolines KW - helicates KW - copper(I) complexation KW - optoelectronic properties AB - We report the synthesis and comprehensive characterization of a series of (oligo)thiophene-bridged (bis)phenanthroline ligands. The complexation behavior of the ditopic ligands with Cu(I) was explored by high-resolution ESI mass spectrometry, UV-vis spectroscopy, and electrochemistry. Whereas ligands, in which the phenanthrolines are bridged by smaller (oligo)thiophene units, provided mainly mononuclear complexes, quaterthiophene-based ditopic ligands show a strong tendency to undergo metal-templated self-assembly into double-stranded, dinuclear helicates.
