Abstract
Novel light-harvesting compound 6, based on 1,8-naphthalimide donors and perylenediimide acceptor were synthesized. The light-harvesting compound 6 showed intensive absorption band in range between 390 and 560 nm, that is 50 nm wider in comparison with the absorption of the model perylene dye. The novel antenna 6 has a higher ability to collect photons from environment in comparison with the single perylene diimide dyes. The chosen fluorophore units are suitable donor–acceptor pair for light-harvesting materials which was in agreement with their good antibacterial activity.
