Certain systems of molecules react when exposed to UV light via photodimerization―a process in which two molecules form chemical bonds to become one single unit. Trans-1, 2-Bis (4-Pyridyl) Ethylene (BPE) is one such molecule which exhibits a 2+2 photodimerization when co-crystallized with an appropriate molecule, otherwise known as a template.
Up until now, photochemical experiments in undergraduate laboratories were rare due to the relatively high costs of commercially available BPE and the photoreactor required to carry out the reaction. This poster outlines a cost-effective and simple procedure to synthesize BPE and introduces the pioneer use of a low-cost Professional UV Gel Light Nail Dryer as our photoreactor-substitute, which not only gave results comparable to those by high-end photoreactors, but also operated with greater energy efficiency.
