The intramolecular electronic energy transfer between two chromopliorcs separated by a methylene chain has been observed in an isolated molecule. The molecules studied are 1 \_(o-tolyl)-3-@-tolyl)propane (I) and I-(m-tolyl)-3-@-tolylk propane (II). The energy transfer rate from o-or m-xylcnc moiety
## Abstract Photophysical properties of a porphyrinβphthalocyanine heterodimer covalently linked with a dipentoxy chain have been studied. Absorption spectra show that there is weak exciton coupling between the two chromophores in the ground state. Fluorescence spectra show that intramolecular ener
