ABSTRACT:
Solid-state fluorescent composition comprising at least one host chromophore selected from the group consisting of a benzo[4,5] imidazo[2,1-a]isoindol-11-ones and an effective amount of at least one guest chromophore, and if desired a polymer C, wherein the emission spectrum of the host chromophore overlaps with the absorption spectrum of the guest chromophore, and wherein (a1) the host chromophore is covalently linked to a polymer backbone A ("host polymer"), and/or (a2) the guest chromophore is covalently linked to a polymer backbone B ("guest polymer").
