Abstract:
Fluorescent dyes useful for detecting a target material in biological assays an electron donating moiety which is linked by a conjugated π-electron bridge to an electron accepting moiety. The π-electron bridge includes at least one carbocyclic ring structure or heterocyclic ring structure. The electron accepting moiety is a carboxylic acid, a salt of a carboxylic acid, or has the formula: wherein:X8 is selected from the group consisting of H, CH3, and (CH2)n6-Z2−, where Z2− is a monovalent anion; and n6 is an integer from 1 through 10; andQ3 is O or S.
Abstract:
The present invention is directed to chromophores having novel electron withdrawing groups and novel bivalent cyclic bridges and to optical waveguides and optical devices having polymeric thin films which contain the novel chromophores.
Abstract:
Devices include a substrate, a collector layer, and an emitter layer positively biased relative to the collector. Devices further include a semiconductor layer located between the collector and the emitter. The semiconductor layer includes an organic semiconductor polymer with a donor-acceptor structure.
