Abstract: Abstract We report the nonlinear optical absorption and optical limiting studies of 5,15-di(pyridyl)-10,20- bis(pentafluorophenyl)porphyrin and its metal complexes with Cu(II) and Zn(II) in chlorobenzene under nanosecond regime. All the samples were found to exhibit significant… read more here.
