Abstract

We have synthesized and characterized by IR, UV, 1H, and 13C NMR spectroscopy new spiropyrans based on 2-thioxo-3 phenyl-5,5-dimethyl-1,3-oxazolidine. We have studied their photochromic properties in 2 propanol at ‒80°C. In the electronic spectra of photo-induced forms, we have detected two long-wavelength absorption bands in the 370–438 and 480–677 nm region.
