Results obtained show that photo-dimerization of polyanthracene will proceed upon exposure with visible light LEDs with reduction in efficiency at longer wavelengths. 4x more efficient than the non-substituted monomer counterpart. At 381 nm, photo-dimerization of the material was found to be approx. The photo-dimer product formation decreased from 381 nm to 468 nm and was found to be higher for the polyanthracene material compared to the monomer anthracene.
Upon exposure to ultraviolet-visible LEDs, photo-dimerization of polyanthracene in solution occurred and was monitored using UV-VIS spectroscopy. A decrease in surface hydrophobicity of a polyanthracene-coated poly(methylmethacrylate) substrate from 109.11° to 60.82° was observed upon UV-C exposure for 48 hrs which was attributed to increase in oxygen content at the surface, as validated by energy dispersive X-ray spectroscopy. The material was prepared via one-pot chemical oxidation route using FeCl 3 as oxidizing agent. The wavelength-dependent photo-reactivity of polyanthracene was explored upon UV-C and VIS light irradiation.
