Abstract
In the present work, Langmuir-Blodgett (LB) processing of a non-amphip hilic monomer, 1,4-bis(3-quinolyl)-buta-1,3-diyne (DQ) and the attempt s 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 mo nolayers were studied by pi-A isotherm and the transferred LB films we re characterized by UV-visible spectroscopy, X-ray diffraction (XRD) a nd UV-irradiation studies. Results show that, in contrast to its bulk reactivity, DQ does not undergo DQ --> PDQ conversion in the LB film s tructure. Preparation of PDQ LB films from PDQ monolayer has also been discussed.
