A series of piperidine-naphthalene monoimide, donor−acceptor (D−A) chromophores and their thionated derivatives were prepared. The physical properties the studied by spectroscopic electrochemical measurements DFT calculations. Relative to non-thionated counterparts, D−A display enhanced visible-light absorption 1O2-sensitization quantum yields negligible fluorescence, suggesting facile triplet ...

Photosensitization properties of coronene-purine (Cor-P) hybrids for photodynamic therapy (PDT) have been investigated in this work. Eight hybrid Cor-P models have been designed by the additional of adenine (A) and guanine (G) nucleobase to Cor species. The evaluated absorption and emission energies indicated that the singular models are not good at all for PDT process whereas their hybrid mode...
