摘要：
The functioning of tetraalkanoyl oxyhydroquinone homologues on the air-aqueous interface was investigated. The pi-A isotherms of homologues 6, 7 and 8 featured two plateaus. The LB films formed were transferred onto silicium and glass supports; their structure was investigated by small-angle X-ray scattering. A model of the molecule packing in the layer is proposed. Three compounds investigated formed a discotic liquid-crystal phase in bulk in a definite temperature range. The phase transition <<solid crystal - liquid crystal>> in LB films of discogens was investigated. The comparative analysis of the structure parameters of LB films and the volume phases was carried out.
