Research Abstract

The circularly polarised light (CPL)-pumped mirror symmetry breaking experiment with achiral fluorene-alt-biothiphene copolymer (PF8T2) as polymer particles dispersed in poorer organic solvents was demonstrated. CPL-pumped chiroptical generation, racemisation, inversion and retention were effectively achieved by finely tuning the media and the wavelength, pumping time. Additionally, circularly polarized luminescence by the PF8T2 particles with quantum efficiency of ca 0.1 were observed. For comparison, no CPL-induced optical activity of PF8T2 in solution was detected under similar conditions.
