Synthesis and characterization of Vitamin-Derived Conductive Polymers

Electrochemical polymerization of biologically relevant molecules, such as vitamins, presents an innovative approach to developing biocompatible and environmentally friendly conductive polymers. Unlike synthetic monomers, vitamins possess inherent redox activity [1]. Several vitamins, including riboflavin (vitamin B2) and folic acid (vitamin B9), can undergo electrochemical polymerization, forming conductive films suitable for sensing applications [2, 3]. 

This study explores the electrochemical polymerization of thiamine (vitamin B1) and pyridoxal (vitamin B6) to synthesize novel materials for (bio)sensing. Thiamine and pyridoxal contain functional groups—hydroxyl, aldehyde, and amino—that enable redox reactions and thus their polymerization [4, 5].

Research focuses on optimizing polymerization parameters such as applied potential, polymerization solution pH, and monomer concentration to achieve stable and conductive polymer films. 

Optimization and functionalization studies will enhance material properties. Characterization of the resulting polymers will be conducted using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM).
