Abstract

AbstractStimuli responsive luminescent materials possessing room temperature phosphorescence (RTP) are extremely desirable for various applications. The here investigated derivative of cyclic triimidazole (TT) functionalized with carbazole (Cz), namely TT‐Ph‐Cz, belongs to this class. TT‐Ph‐Cz possesses high conformational freedom resulting in rigidochromic and multi‐stimuli responsive emissive behavior. It has been isolated as MeOH‐solvated and de‐solvated forms characterized by distinctive emissive features. In particular, the solvated form, in which hydrogen bonds with MeOH inhibit competitive non‐radiative deactivation channels, possesses a higher quantum yield associated with a strong phosphorescence contribution which is preserved in DMSO/water solutions.
