CHEMICAL SENSOR CONTAINING ARYLENE/ALKENYLENE OLIGOMER

摘要

PROBLEM TO BE SOLVED: To enhance the response speed, range, sensitivity and stability of a detector used for an analytical object in a liquid by providing a chemical sensing probe containing an arylene/alkenylene oligomer or a blend of a plurality of olibomers. ;SOLUTION: A chemical structure of an arylene/alkenylene oligomer are all of possible sequences of one or more of an aromatic or heterocyclic aromatic unit like benzene, thiophene, pyrrole, aniline, indole and other many units (arylene segments) capable of being bonded by one or more alkenyl segment [-(CR=CR'-)_n]. The skeleton thereof may be substituted on an aryl segment in the same way as an alkenyl segment. A kind of a substituent exerts effect on the partial selectivity of coating, the solubility of the oligomer, the oxidation potential of them and nominal electric conductivity.;COPYRIGHT: (C)1999,JPO
