Outline of Final Research Achievements

This research project aims at the emergence of intrinsic circularly polarized luminescence (CPL) features from chiral conjugated molecules. For this purpose, we constructed an original optical system to enable precise measurement of CPL spectra from the chiral conjugated molecules. We succeeded in the measurement of CPL spectra by combining both photoelastic modulators (PEM) and excitation laser. We will demonstrate the precise CPL spectral measurements of chiral conjugated molecules at various situations such as solid-state crystals or films through our original optical measurement system.
