- Steady state and time resolved spectroscopic measurements on an organic dyad, 1-(4-chloro-phenyl)-3-(4-methoxy-naphthalen-1-yl)-propenone, where the donor 1-methoxynaphthalene is connected with the acceptor p-chloroacetophenone by an unsaturated olefinic bond, in presence of TiO2 nanoparticles were made at the ambient temperature. Time resolved fluorescence measurements reveal that the rate parameters associated with charge separation, k cs, within the dyad increases whereas charge recombination rate reduces when the surrounding medium is changed from chloroform to TiO 2 nanoparticles. The observed results indicate that the dyad being combined with TiO2 nanoparticles may form organic-inorganic nanocomposite systems useful for developing light energy conversion devices.
