A composition comprising (a) an effective amount of a guest chromophore embedded in a matrix of a host chromophore, or (b) a host chromophore and an effective amount of a guest chromophore both embedded in a polymer matrix, wherein the absorption spectrum of the guest chromophore overlaps with the fluorescence emission spectrum of the host chromophore, and wherein the host chromophore is selected from the group consisting of benzo &lsqb;4,5&rsqb;imidazo&lsqb;2,1-a&rsqb;isoindol-11-ones.

Benzo (4,5) imidazo (2,1-a) isoindol-11-ones

A composition comprising (a) an effective amount of a guest chromophore embedded in a matrix of a host chromophore, or (b) a host chromophore and an effective amount of a guest chromophore both embedded in a polymer matrix, wherein the absorption spectrum of the guest chromophore overlaps with the fluorescence emission spectrum of the host chromophore, and wherein the host chromophore is selected from the group consisting of benzo &lsqb;4,5&rsqb; imidazo &lsqb;2,1-a&rsqb; isoindol-11-ones.

Fluorescent materials and their use

Process for the preparation of fluorescent compositions, fluorescent compositions and their use

Composition comprising a solid organic support material to which either directly or via a bridging group, are covalently linked fluorescent host chromophores and fluorescent guest chromophores, wherein the fluorescence emission spectrum of the host chromophore overlaps with the absorption spectrum of the guest chromophore, wherein the host chromophore is selected from the group consisting of benzo[4,5]imidazo[2,11-a]isoindol-11-ones.

Fluorescent host-guest-system

A composition comprising a solid organic support material to which are either directly, or via a bridging group, covalently linked fluorescent chromophores, characterized in that the chromophores are selected from the group consisting of benzo[4,5]imidazo[2,1-a]isoindol-11-ones.

Fluorescent chromophore, covalently linked to an organic support material

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').
