Oligoamylose-entwined porphyrin: excited-state induced-fit for chirality induction

An oligoamylose-strapped porphyrin displayed circularly polarized luminescence (CPL) in the S 1 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. An oli...
