CAS 50907-23-8: 5-(4-Bromophenyl)-2H-tetrazole

5-(4-Bromophenyl)-1H-tetrazole

5-(4-Bromophenyl)-2H-tetrazole is a heterocyclic compound that can be synthesized by a cross-coupling reaction of 2,3-dibromobenzene and 4-bromoaniline. It has been used as an organic semiconductor in the fabrication of solar cells. This compound has been shown to absorb light in the visible spectrum (400-700 nm) and to have a potential for conversion into electricity. The absorption spectrum shows that 5-(4-bromophenyl)-2H-tetrazole absorbs light at wavelengths below 700 nm more efficiently than those above 700 nm. The photovoltaic effect is dependent on the nature of the anion, chloride being the most effective.
