Abstract

Planar-chiral Phanephos, containing the coordinatable P(III), formed P(III)/Tb(III)(hfa)₃ hybrid luminophores that successfully emitted characteristic circularly polarised luminescence (CPL) due to ⁵D₄ → ⁷F₅ transitions in solution. On the other hand, BINAP, containing P(III) [double bond, length as m-dash] O as axially chiral ligand, exhibited no detectable CPL with Tb(III)(hfa)₃.
