title: Synthesis, structure and photophysical properties of a 2-(1'-hydroxypyrenyl)benzothiazole.
abstract: A pyrene-based 2-aryl-benzothiazole derivative, 2-(1'-hydroxypyrenyl)benzothiazole (1H2PBT), was synthesized. Its crystal structure and photophysical properties were investigated. In comparison with the generally studied parent compound, 2-(2'-hydroxyphenyl)benzothiazole (HBT), 1H2PBT exhibited red-shifted absorption and emission in solution, as well as impressive solid state emission with high efficiency (0.35).
