Abstract

Two donor-acceptor molecular systems consisted of tetrathiafulvalene (TTF) and fluorescein were designed and synthesized. The target compounds and their key intermediates were characterized by H NMR, mass spectrography, and infrared spectroscopy, respectively. The UV-vis spectra implied intramolecular interaction in their ground state. Fluorescence spectra and fluorescence lifetimes indicated the photoinduced charge transfer (PET) interaction between the TTF and fluorescein units in their excited states.
