An undergraduate laboratory experiment is described utilizing modified carbon platinum, and gold electrodes with organic conductive polymers such as poly-p-phenylene (PPP), These polymers are grown electrochemically and utilized to detect 1,2-dihydroxybenzenes.  Cyclic Voltammetry (CV) was utilized to determine the stability, longevity, reversibility and diminishing fouling problems typically associated with conductive polymers. This experiment also examines different types of electrode surfaces carbon, platinum and gold modified with polymer PPP.   FTIR may be utilized to illustrate the modification or the electrode surface (covalent bonding of the polymer).  This lab motivates students to learn novel skills with integrated lab equipment and techniques that build upon problem-solving skills needed to succeed as STEM (Science, Technology, Engineering and Mathematics) majors. Also, this lab illustrates an excellent first year chemistry lab to offer as the introduction of metals and nonmetals (electrode surfaces and polymer) and build skills to prepare for the second year of Organic Chemistry (the application of FTIR  and Raman skills with mode assignments to confirm the PPP on the electrode surfaces).
