Synthetic Route of C51H42O3Pd2In 2019 ,《Significant Difference in Semiconducting Properties of Isomeric All-Acceptor Polymers Synthesized via Direct Arylation Polycondensation》 was published in Angewandte Chemie, International Edition. The article was written by Wang, Yang; Hasegawa, Tsukasa; Matsumoto, Hidetoshi; Michinobu, Tsuyoshi. The article contains the following contents:
The direct arylation polycondensation (DArP) appeared as an efficient method for producing semiconducting polymers but often requires acceptor monomers with orienting or activating groups for the reactive carbon-hydrogen (C-H) bonds, which limits the choice of acceptor units. In this study, we describe a DArP for producing high-mol.-weight all-acceptor polymers composed of the acceptor monomers without any orienting or activating groups via a modified method using Pd/Cu co-catalysts. We thus obtained two isomeric all-acceptor polymers, P1 and P2, which have the same backbone and side-chains but different positions of the nitrogen atoms in the thiazole units. This subtle change significantly influences their optoelectronic, mol. packing, and charge-transport properties. P2 with a greater backbone torsion has favorable edge-on orientations and a high electron mobility μe of 2.55 cm2 V-1 s-1. Moreover, P2-based transistors show an excellent shelf-storage stability in air even after the storage for 1 mo. After reading the article, we found that the author used Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Synthetic Route of C51H42O3Pd2)
