Abstract
Disclosed are ion-sensitive polymers and methods for their use for monitoring biological phenomena associated with ion fluxes, as well as organic electrochemical transistors including such polymers.
Claims2
A method for coating an electrode or for manufacturing an organic electrochemical transistor, comprising:
- providing at least one polymer comprising at least one unit of formula (I)
- wherein
- A is a polymerisable monomer, said polymerizable monomer being 3,4-ethylenedioxythiophene,
- L is a spacer arm, wherein the spacer arm is a group comprising at least one carbon, hydrogen, phosphorus, sulfur, nitrogen and/or oxygen atom, and
- B is a chemical group capable of complexing or chelating at least one ion selected from the group consisting of K+, Na+, Ca2+ and Zn2+, and
- depositing, using electropolymerization, the at least one polymer comprising at least one unit of formula (I) on the electrode or on the substrate of the transistor,
- wherein either the polymer comprising at least one unit of formula (I) is an electronically conductive polymer, or the polymer comprising at least one unit of formula (I) is electronically non-conductive and is used in the form of a mixture with another electronically conductive polymer.
