D●–A Radicals Fabricated from Polychlorinated Trityl and Pyridinium Featuring a SOMO–LUMO Electronic Transition
Abstract
D●–A radicals 2a–2c were developed by combining a polychlorinated trityl as donor with a pyridinium as acceptor. The electron-deficient nature of the pyridinium unit significantly lowers LUMO energy, thereby enabling SOMO–LUMO (α-type) electronic transition, in contrast to conventional luminescent radicals that predominantly exhibit HOMO–SUMO (β-type) transition.
