Abstract

In this study, we report on the optical properties of a photochromic thiazolo[5,4-d]thiazole-embedded in polymer in the visible and near infrared spectral range determined using spectroscopic ellipsometry. The dielectric functions for the yellow (TTz²⁺) and blue (TTz⁰) states were extracted from a numerical wavelength-by-wavelength inversion of the experimental data. The extracted dielectric functions are in good agreement with a Kramers-Kronig consistent B-spline-based model analysis of the experimental data. The thiazolo[5,4-d]thiazole-embedded polymer exhibits several strong absorption bands from the visible to the near infrared spectral range depending upon their redox states.
