Photochemistry and Photophysics of the 3‐Styrylidenebenz[e]indanes

open access: yesPhotochemistry and Photobiology, 2018
AbstractThe photochemical and photophysical properties of the extended conformers of trans‐ and cis‐1‐(2‐naphthyl)‐2‐phenylethenes (t‐ and c‐NPEB) are strikingly different than those of their rigid analogues, trans‐ and cis‐3‐styrylidenebenz[e]indane (t‐ and c‐BPE). The fluorescence quantum yield and lifetime at 25°C in methylcyclohexane drop from 0.76
