METHOD OF DETECTING REAGENT, POLYMER, ELECTRODE PASTE, ELECTRODE, AND CALYXARENE Russian patent published in 1999 - IPC

FIELD: analytical methods. SUBSTANCE: invention aims at receiving reliable signal significative of "host-quest" interaction and consists in mixing all or a part of material with liquid, measuring any variation in electric behavior (conductivity) of calyxarene when being kept in solution or suspension or after keeping as compared to reference condition, such variation being regarded as reagent presence signal. Calyxarene placed into solution or suspension is depicted by formula (shown in description) wherein y¹-y⁴, are selected from the group including: hydrogen, alkyl, alkenyl, aryl, arylalkyl, or substitute exhibiting redox activity, R¹-R⁴ are selected from the group including: hydrogen, alkyl, alkenyl, aryl, arylalkyl, or polymerizable fragment; at least one of y¹-y⁴, being substitute exhibiting redox activity. EFFECT: facilitated analytical procedure. 27 cl, 1 tbl, 8 ex
