Abstract

An oligoamylose-strapped porphyrin displayed circularly polarized luminescence (CPL) in the S1 state despite being silent in circular dichroism (CD) in the ground state, suggesting chirality induction in the photoexcited porphyrin moiety from the oligoamylose-strap in the photoexcited state.
