Mesityl-Substituted Acene Radical Cations: Decent Stability Comparable to Their Neutral States under Ambient Light and Air

摘要

Anthracene, tetracene, and pentacene, with moderately bulky mesityl substituents revealed that their photochemical stability in solution under ambient light and air conditions is comparable to that of the corresponding neutral state, thus indicating the possibility of persistent acene radical cations.
