Conformational dependence of triplet energies in rotationally‐hindered N‐ and S‐heterocyclic dimers: new design and measurement rules for high triplet energy OLED host materials

A series of four heterocyclic dimers has been synthesized, with twisted geometries imposed across the central linking bond by ortho‐alkoxy chains. These include two isomeric bicarbazoles, a bis(dibenzothiophene‐S,S‐dioxide) and a bis(thioxanthene‐S,S‐dioxide). Spectroscopic and electrochemical metho...
