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 (ΦFL) 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 lgabsl ¼ 0.20 at 615 nm and lgluml =0.022 at 660 nm, respectively. The glum profiles significantly expanded up to ca. 850 nm.
