Abstract

Reductive photodehalogenation of chloroaromatics is assumed to proceed from the triplet excited state, although its energy is often insufficient to promote a clean homolytic C¿Cl cleavage. A clear-cut experimental proof is provided that correlates self-quenching of the directly observed triplet excited states of chlorocarbazole-based dyads 1 and 2 with photoreactivity via intramolecular charge transfer. ; Spanish Government (CTQ2010-14882, BES-2011-043706, JCI-2010- 06204) ; Generalitat Valenciana (Prometeo 2008/ 090 and GV/2012/041) ; Limones Herrero, D.; Pérez Ruiz, R.; Jiménez Molero, MC.; Miranda Alonso, MÁ.
