Abstract:
A solid 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 at least one guest chromophore, wherein the weight ratio between host chromophores and guest chromophores is 50:50 to 9999:1, 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"").
