Three asymmetrically substituted 1,3-diphenyl-6,8-R-disubsituted pyrenes were fully characterized by X-ray crystallography, photophysical properties, electrochemistry, and density functional theory calculations. 2015-11-09 14:31:59 untagged Chemical Sciences not elsewhere classified Organic Chemistry
