Abstract

This chapter focuses on the structural and photophysical control of fluorescent helicene derivatives and related homoleptic zinc(II) helicates for improved circularly polarized luminescence properties. Our synthetic strategy enables to significantly enhance the fluorescence quantum yield (Φ_FL) of helicene derivatives for observation of circularly polarized luminescence (CPL). Moreover, the zinc(II) helicate also demonstrated unusually strong chiroptical responses with absorption and luminescence dissymmetry factors such as lg_absl ¼ 0.20 at 615 nm and lg_luml =0.022 at 660 nm, respectively. The g_lum profiles significantly expanded up to ca. 850 nm.
