Title: A comparative study of the photophysical properties of perylenediimides in liquid phase, PVC and sol-gel host matrices
Abstract: The photophysical and photochemical properties of three different perylenediimide derivatives, N,N′-di-dodecylperylene-3,4,9,10-bis(dicarboximide), N,N′-di-(1-dehydroabietyl)perylene-3,4,9,10-bis(dicarboximide) and N,N′-di-(4-carboxy phenyl)perylene-3,4,9,10-bis(dicarboximide) (N-DODEPER, ABIPER and PECA, respectively), were determined in immobilized phases (PVC films, both plasticized and non-plasticized, and sol-gel matrix) using steady state fluorescence spectroscopy and compared with the data in solution phase. It was found that the plasticizers support the interaction of the dyes with the quencher and bis-(2-ethylhexyl)phthalate (DOP) itself acts as a quencher for the perylenediimide derivatives with aromatic substituents. The sol-gel matrix imparted serious changes to the properties of the perylenediimides.
