Abstract
Rhodium dinuclear complexes containing azobenzene-bridged bis(terpyridine), tpy-AB-tpy, were synthesized, and their trans-to-cis photoisomerization be havior was examined. The photoisomerization rate depends on the size of the counterion and the polarity and viscosity of the solvent. In electrochemic al measurements, the reduction potential due to Rh(III)/Rh(I) of the cis fo rm of the complex was shifted in a negative direction from the trans form. [GRAPHICS]
