Paper Abstract

We have recently initiated a research project that aims at understanding how systematic variations of the number and positioning of a given Inter-System Crossing (ISC) promoter (1,4-dibromophenyl) along the Intramolecular Charge Transfer (ICT) axis of chromophores will affect the outcome of singlet oxygen production, and how this effect will be related to the nature of the ICT transition. In this communication, this strategy is discussed and we show that a clear influence of the ISC promoter’s position on the chromophore exists, which can be used both to improve the singlet oxygen generation efficiency of the sensitizer, but also its linear and nonlinear spectroscopic features.
