A mixed-valence bis(diarylamino)stilbene:crystal structure and comparison of electronic coupling with biphenyl and tolane analogues

摘要

The E-4,4'-bis[di(p-anisyl)amino]stilbene cation is a class-III mixed-valence species with electronic coupling comparable to that in its biphenyl-bridged analogue,whereas its tolane-bridged analogue belongs to class II.Mixed-valence (MV) species based on triarylamine redox centers have recently attracted considerable interest.
