FIELD: organic chemistry, polymers, chemical technology.
SUBSTANCE: invention relates to novel polymeric materials - membranes, films and monolayers based on compounds of novel type - dithiacrown-containing dyes of the general formula (I):
wherein R1-R4 mean hydrogen atom, lower alkyl, alkoxyl group, aryl group, or two substitutes R1 and R2, R2 and R3, R3 and R4 form in common CH4-benzo-group; R5 means alkyl radical CH2m+1 wherein m = 1-18; X means chlorine (Cl), bromine (Br), iodine (J) atoms, groups -ClO4, -PF6, -BF4, -PhSO3, -TsO, -ClC6H4SO3, -CHSO3, -CF3SO3, -CH3OSO3; Q means sulfur atom, oxygen atom, selenium atom, group -C(CH3)2, group -NH, group -NCH3; n = 0-3. Also, invention describes a method for synthesis of such compounds and composite materials based on thereof possessing ion-selective optical properties. Proposed dyes and composite materials based on thereof possess the high selectivity to heavy and transient metal ions and can be used as components of optical chemosensors, for example, as components of polymeric membranes, ultrafine films and molecular monolayers, for determination of trace amounts of indicated ions in industrial waters and sewages, among them, for monitoring the environment, in biological fluids and others.
EFFECT: improved methods of synthesis, valuable properties of materials.
