ABSTRACT:
A luminescent polymer, suitable for use in an active layer of an organic light-emitting device, organic solid state lasers, a photovoltaic cell or an electrochromic display and exhibiting good stability and microstructure control, which has the structurewherein Ar1and Ar2are aromatic or heteroaromatic rings, such as phenyl, biphenyl, fluorene, thiophene, pyridyl, or their substituted aromatic or heteroaromatic rings with or without deuterium, and R1and R2are independently each selected from the group consisting of hydrogen, deuterium, substituted or unsubstituted alkyl, alkoxyl, aryl and heteroaryl, or halogen, wherein D represents deuterium and n is an integer greater than 3. Electronic devices and methods of making them which employ these luminescent polymers are also described.
