Abstract
In the present work, Langmuir–Blodgett (LB) processing of a non-amphiphilic monomer, 1,4-bis(3-quinolyl)-buta-1,3-diyne (DQ) and the attempts to obtain PDQ LB films from DQ LB films are presented. LB processing has been carried out with pure DQ and of DQ mixed with arachidic acid and 10,12-pentacosadiynoic acid. Characteristics of pure and mixed monolayers were studied by π–A isotherm and the transferred LB films were characterized by UV-visible spectroscopy, X-ray diffraction (XRD) and UV-irradiation studies. Results show that, in contrast to its bulk reactivity, DQ does not undergo DQ→PDQ conversion in the LB film structure. Preparation of PDQ LB films from PDQ monolayer has also been discussed.
