✦ Synopsis

The photoelectric behaviours of covalently linked porphyrin-donor-acceptor compounds: diad, triad, tetrad and porphyrin with Cl6 alkyl substitute incorporated into molecular laver assemblies by LB film technique have been investigated. The photovoltages and photocurrents were measured and compared for monolayer of their LB films. The increase of photovoltages and photocurrents with the order tetrad > triad > diad > TPP-OC16H33 indicates that the photoelectric behaviours can be improved successfully in the well designed porphyrin linked donor-acceptor compound systems.
