Excitation of an amphiphilic anthracenoâruthenium complex, which
serves as an antenna-sensitizer complex, leads to two kinds of anthracene
triplet states, one of which is bleached by a hydrophilic acceptor and the
other by a hydrophobic acceptor in dihexadecyl phosphate vesicles; the
latter process is directional from the surface to the interior of the
bilayer membrane.

A series of (2,2′-bipyridine)platinum(II) complexes covalently tethered to one or two anthracene or naphthalene chromophores was synthesized in high yields. The compounds were equilibrated with pUC19 plasmid and then irradiated at 350 nm. DNA cleaving reactions showed that the complex attached to two anthracene units exhibited the highest photocleavage efficiency, leading to complete conversion of
