Synthesis, characterization, and optical properties of 2-amino-4-aryl-6-(9,9′-spirobifluoren-2-yl)pyrimidines
摘要:
A series of 2-amino-4-aryl-6-(9,9'-spirobifluoren-2-yl)pyrimidines have been synthesized by the reaction of guanidine and chalcones under basic conditions. The physical and optical properties indicated that these compounds generally show good blue light emissions and excellent thermal stabilities. Intermolecular hydrogen bonds and interactions have strong influences on their properties.
