Optical properties of poly(diphenylenephthalide) nonconjugated polymer films near the electronic switching threshold have been studied by modulation spectroscopy. The measured spectra exhibit specific features in the range of the band gap at ∼2.4 eV. The results obtained have been interpreted using...
