Description
Summary:[Display omitted] 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 (∼30nm) to the longer wavelengths during the sample UV irradiation corresponds to a continuous increase of the polymeric chain conjugation length. The morphology of mono-layers was determined by the scanning electron microscopy.
