Circularly polarised luminescence (CPL) and photoluminescence (PL) properties of pi-conjugated (R)- and (S)-2,2'-diphenyl-4-biphenanthrol (VAPOL) exhibited an efficient CPL (similar to 1.3 x 10(-3)) with a quantum yield (Phi(F)) 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.
