Room-temperature phosphorescence of poly(p-vinylbenzophenone) in solution
The phosphorescence emission of polymers and copolymers of p-vinylbenzophenone (VB) can be detected in chloroform and benzene solutions at room temperature, when oxygen is carefully removed. Their spectroscopic properties are close to those of benzophenone (B), but changes in the vibrational structure and an increase of E-type delayed fluorescence is observed. The measurement of absolute quantum yields of phosphorescence in poly(p-vinylbenzophenone) and the observation of quenching in p-vinylbenzophenone-vinylferrocene copolymers are in agreement with previous photochemical results: no triplet energy migration between benzophenone units in the polymer chain in solution could be inferred from these results.
