For UV-A initiated polymerization reaction, 500 L of EDOT (ca. 5 mmol), 500 L of ECL (ca. 5 mmol), 100 mg of PAB (ca. 5 mmol) were dissolved using 500 L dichloromethane (DCM) solvent inside a Schlenk tube which was previously heated-vacuumed-degassed three times using nitrogen gas. Schlenk tube was then placed inside a photo-reactor equipped with a magnetic stirrer, cooling fan and 18 fluorescent lamps (Philips TL 18W BLB) emitting light nominally at 355 nm with a light intensity of ~100 mW/cm 2 (measured using Delta OHM Quantum radio photometer) at reaction flask (Fig. ). After 4 h of irradiation, the initial yellow colored reaction mixture turned to dark blue-black color (Fig. ). Then, the mixture was precipitated into 10-fold methanol and the resultant dark blue/black colored solid was washed with n-hexane to remove the unreacted monomers, side product (acetophenone) and the catalyst. For visible light initiated bulk polymerization, 300 mg of PAB was dissolved in 1 mL mixture of EDOT and ECL (500 L of each) and was transferred into a Teflon mold which was later irradiated for 2 h using a Rofin Polilight PL400 equipped with a 400 W of metal halide lamp operating at 415 nm (Fig. ).
