Abstract
The preparation of different styrene-based polymer films containing small amounts of tetraphenylethylene (TPE) and the evaluation of their photoluminescent behavior are reported. TPE molecular rotors show brilliant blue emission in a poor solvent or in a glassy styrene-based polymer matrix, where the intramolecular rotations of its aryls result as being completely arrested, but the fluorescence is weakened to pale green and eventually to a faint signal when good solvents or viscous but not glassy polymer matrices are used. This behavior suggests potential benefits in applications such as polymer traceability. Further details can be found in the article by G. Iasilli, A. Battisti, F. Tantussi, F. Fuso, M. Allegrini, G.
