Fig. 1: Molecular structures and photo-thermo-induced phosphorescence.
From: Photo-thermo-induced room-temperature phosphorescence through solid-state molecular motion
a Rational design of molecular rotors and successively elevated photothermal temperatures on going from o-Br-TRZ to m-Br-TRZ to p-Br-TRZ. b Sequential photo-thermo-induced phosphorescence (taking p-Br-TRZ as the example): (i) when irradiated with 365 nm UV light, p-Br-TRZ shows a photothermal effect through molecular motion, with a peak temperature of 102 °C; (ii) schematic representation of ordered molecular arrangement-induced phosphorescence through photothermal annealing, accompanied by ordered molecular arrangement.
