    Photopolymerization of Langmuir-Schaefer monolayers of 12-hydroxy-7,9-dodecadiyn-1-yl N-(4-methoxyphenyl)carbamate molecules under long-term UV irradiation provided the new polymer material. The observed blue phase polymer absorption band shift (similar to 30 nm) to the longer wavelengths during the sample UV irradiation corresponds to a continuous increase of the polymeric chain conjugation length. The morphology of monolayers was determined by the scanning electron microscopy.
