The ability of triacetylenic acids with the general formula CH3(CH2)m C≡C-C≡C-C(CH2)8COOH, where m = 7, 11, and 16, to form monolayers and Langmuir-Blodgett films was investigated. The kinetics of UV-photopolymerization of multilayers was studied by UV and IR-spectroscopy and automatic ellipsometry. It is shown that the monolayer stability and the collapse pressure increase with m. The triacetylenic acid films possess a high rate of photopolymerization, which 5 to 10 times exceeds the rate of photopolymerization of respective diacetylenes. The possible mechanism of topochemical polymerization is discussed.
