A Rigid Polymer Donor Based on a Simple Benzodithiophene–Thiazole Backbone for Organic Photovoltaics
ChemSusChem, EarlyView.A new polymer donor, PBDTTz, with a simple benzodithiophene–thiazole backbone, features intramolecular N···S interactions that lock the backbone into a rigid, coplanar conformation and enhance π–π stacking, while the electron‐deficient thiazole units also deepen the highest occupied molecular orbital level.
