Abstract

Circularly polarised luminescence (CPL) and photoluminescence (PL) properties of π-conjugated (R)- and (S)-2,2′-diphenyl-4-biphenanthrol (VAPOL) exhibited an efficient CPL (∼1.3 × 10−3) with a quantum yield (ΦF) of 0.20 at 376 nm. By comparison, (R)- and (S)-3,3-diphenyl-2,2-bi-1-naphthol (VANOL) exhibited no CPL or PL.
