The authors' recent activity in the study of photoinduced energy and electron transfer in linear arrays containing porphyrins assembled around a Ru(II) ion, is reviewed. The effect of substituents and distance and the role of the heavy metal ion is discussed. The photophysical and electrochemical properties of Ir(III) terpyridine complexes indicate that Ir(III) ion is a good candidate to successfully replace Ru(II) in the construction of multiporphyrinic linear arrays to achieve efficient photoinduced electron transfer. Preliminary results on multi-porphyrinic systems based on Ir(III) bis-terpyridine are presented. (C) 1999 Elsevier Science S.A. All rights reserved.

Abstract
The authors' recent activity in the study of photoinduced energy and electron transfer in linear arrays containing porphyrins assembled around a Ru(II) ion, is reviewed. The effect of substituents and distance and the role of the heavy metal ion is discussed. The photophysical and electrochemical properties of Ir(III) terpyridine complexes indicate that Ir(III) ion is a good candidate to successfully replace Ru(II) in the construction of multiporphyrinic linear arrays to achieve efficient photoinduced electron transfer. Preliminary results on multi-porphyrinic systems based on Ir(III) bis-terpyridine are presented. (C) 1999 Elsevier Science S.A.
