Preparation of organic layers on liquid surfaces has been a topic for the scientific curiosity for more than hundred years. By this low–cost production method the variety of materials with important electrical, optical, structural and chemical properties can be made. However, in spite of the relatively good investigation of structure and properties of Langmuir films (LF), their use still did not become commercial. The main obstacle is the pure stability of organic layers on liquid sub phase. One way to overcome this problem is to use the organic molecule with ability to be polymerized after arrangement on the liquid surface. For this purpose in the present work the amphiphilic molecules containing either the diacetylene (PDA) or thiol part (TDT), which can be easily initiated for the polymerization, were used.
The main idea of current research was to investigate the promising systems of ultra – thin organic layer on the gas – liquid interface and find the external parameters, which can control their basic properties such as crystal structure and morphology and advance the realization of the potential applications of this type of materials.
