Abstract

Multicomponent arrays based on a central iridium (III) bis-terpyridine complex (Ir) and free- base, zinc (II) or gold (III) tetraaryl-porphyrins (PH 2, PZn, PAu) have been prepared and characterized. The photophysical properties of dyads PH 2-Ir, PZn-Ir, PAu-Ir, and triads PH 2- Ir-PAu, PZn-Ir-PAu have been determined by steady-state and time-resolved methods either in acetonitrile or in dichloromethane and toluene. In toluene solutions, the triad PZn-Ir-PAu ...
