This work reports on the synthesis and characterization of a new gold nanoparticle-zinc phthalocyanine system, AuNP - S (t Bu )3 ZnPc , prepared by a ligand exchange reaction of tetraoctylammonium bromide with a novel unsymmetrically substituted zinc phthalocyanine which contains one thioester group in the peripheral position [ AcS (t Bu )3 ZnPc ]. The AuNP - S (t Bu )3 ZnPc hybrid was characterized using UV-vis and 1 H NMR spectroscopies. Transmission electron microscopy allowed the estimation of the size, which was calculated to be ~5 nm. AuNPs - S (t Bu )3 ZnPc conjugate showed much lower fluorescence quantum yield values than the AcS (t Bu )3 ZnPc demonstrating either an energy or electron transfer from the ZnPc to the AuNP . The AuNP - S (t Bu )3 ZnPc hybrid has been anchored to a TiO 2 semiconducting layer using lipoic acid. A solid configuration of TiO 2-lipoic acid- AuNP - S (t Bu )3 ZnPc has been prepared by anchoring lipoic acid to the TiO 2 ( TiO 2-LA) and introducing later the TiO 2-LA with free thiol groups in a toluene solution of AuNP - S (t Bu )3 ZnPc . We have also observed by UV-vis and fluorescence measurements the importance of the ZnPc in avoiding AuNP aggregation on the TiO 2 surface.
