Abstract

The facile synthesis and chiroptical properties of a new family of circularly polarized luminescence (CPL) materials, axially chiral 1,1′-bicarbazolyls (BiCz), are reported. The BiCz derivatives emitted intense near-ultraviolet photoluminescence, with a peak at ∼380 nm. The BiCz enantiomers showed mirror-image circular dichroism and CPL, with glum values on the order of 10−4 in solution.
