Electropolymerized Porous Polymer Films on Flexible ITO Using Trifunctional Furan Substituted Benzene Conjugated Monomer for Biosensing

In recent years, conducting polymers is playing a significant role in the field of display devices, transistors, solar cells, sensors and electrochromic windows due to their outstanding optoelectronic and semiconducting properties due to their conjugated backbone. One potential application that is not as widely explored using these materials is biosensing, where advantage is taken of the porosity that can be generated by polymerization of a three-dimensional network. There are various approaches for producing conjugated microporous polymers using trifunctional or multifunctional monomers synthesised via chemical or electrochemical methods. In this work, we have used electropolymerization to synthesize conjugated polymer films on a working electrode of Flexible Indium Tin Oxide (FITO) using a trifunctional conjugated monomer 1, 3, 5-tri(furan-2-yl) benzene (TFB). There are several parameters which influences the formation of a porous polymer film and the most critical ones are substrate conductivity, rough...
