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.

Keywords
