Recent synthetic efforts and photophysical studies will be described towards the dual objectives of photoinduced charge separation and light-driven generation of hydrogen.  The cationic complex [Pt(tolylterpyridine)(phenylacetylide)]+ has been used as a photosensitizer for the reduction of aqueous protons in the presence of a sacrificial electron donor to make H2. In the system studied, triethanolamine (TEOA) serves as the sacrificial reducing agent, methyl viologen (MV2+) acts as an electron transfer agent and colloidal Pt functions as the catalyst for H2 generation.  While H2 evolution is maximized for this system at pH 7, it is also seen at pH 5 and 9, in contrast with earlier reports using Ru(bpy)32+. as the photosensitizer.  Current work is examining using fine TiO2 particles in place of MV2+ as the electron acceptor and relay.  With regard to photoinduced charge separation, several triads have been synthesized and studied using transient spectroscopy.  The results will be discussed.
