Abstract

The IR-140 dye has a maximum of absorption in the near infrared spectral range. It can be used successfully for the initiation of photopolymerization in various organic complexes based on polymers and liquid crystals. In this paper we report the experimental observations of the strong influence of the nematic liquid crystal matrix on the spectral properties of this dye. The character of interaction between the dye and liquid crystalline host and its influence on the wavelength dependence of photopolymerization cross section are analyzed.
