Exploiting P-chemistry to modulate the thermally activated delayed fluorescence of organic fluorophores

Résumé

A series of six organophosphorus emitters featuring phosphinate and phosphinic acid groups as electron-accepting moieties coupled to various arylamine-based donor groups has been synthesized and fully characterized. Their photophysical properties were extensively investigated and the structure property relationships were rationalized using TD-DFT calculations. This work demonstrates that a judicious choice of the P-substituent allows promoting or suppressing the thermally activated delayed fluorescence (TADF). This investigation also offers interesting perspectives toward the preparation of stimuli-responsive TADF derivatives.
