Circularly polarised luminescence and circular dichroism of - and -oligopeptides with multiple pyrenes

Among l - and d -oligopeptides with multiple pyrenes as pendants, the dipeptides with two and three pyrenes showed blue-coloured circularly polarised luminescence as high as | g em | (0.86−1.1) × 10 −2 at around 450 nm, reflecting from exciton couplets of twisted pyrenes.
