Abstract:

Several ruthenium complexes are prepared and the absorption and emission spe-ctra of their solutions in EtOH-MeOH at room temperature are reported. The emis-sial maxima of three complexes 4-substituted 2,2′-bipyridyls occur between 550-650 nm, there is strong absorption down to 500 nm as dyes for possible use in lumine-scent solar collectors.
