Abstract

In this work, an undergraduate-level experiment using 5,10,15,20-tetraphenylporphyrin (H2TPP) and its corresponding Ni(II) and Zn(II) metal complexes was developed. The bandgaps of H2TPP and its Ni(II) and Zn(II) metal complexes were calculated experimentally and theoretically to evaluate their abilities to act as light-harvesting complexes.
