Optically active cofacial ABCD-Pt(ii)–porphyrin dimer exhibits bright circularly polarized phosphorescence

Abstract

Synthesis of an intrinsically chiral cofacial ABCD-Pt(II)–porphyrin (Por) dimer was achieved by the simple Pt-templated synthesis of Por, followed by Suzuki–Miyaura cross-coupling. The isolated enantiomers exhibited bright red circularly polarized phosphorescence with a B_CPP value above 10¹ M⁻¹ cm⁻¹.
