FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention relates to new type of compounds representing crown-containing styryl dyes with ammonium group at N-substitute of heterocyclic residue that can be used as photo- and thermosensitive compounds. Invention describes new crown-containing styryl dyes with ammonium group at N-substitute of a heterocyclic residue. Also, invention describes two variants of the method for their preparing. The first method is based on the interaction of a heterocyclic base quaternary salt with formyl derivative of the corresponding crown-compound, and the second method involves quaternization reaction of crown-containing heteroarylphenylethylene at heterocycle nitrogen atom. Proposed crown-containing styryl dyes are prepared from available raw with high yield and represent compounds of the new type able to stereospecific reactions [2 + 2], i. e. photocyclo-addition and possessing thermochromism properties. ^ EFFECT: improved preparing methods, valuable properties of dyes. ^ 4 cl, 4 dwg, 16 ex |
