Abstract
H₂[(p-CN)₄TPP] (1) was synthesized using pyrrole and p-cyanobenzaldehyde via the Alder-Longo method, followed by Ni metallation with NiCl₂ to produce Ni[(p-CN)₄TPP] (2). Comparison of the UV-Vis spectra of the two compounds revealed that the Q band exhibited five peaks for 1, while only one peak was observed for 2. Comparison of the 1H NMR spectra showed that the chemical shift values decreased by metallation. These analyses demonstrated that metallation altered the electronic environment of 1.

Introduction
Porphyrin (Figure 1 A) is a macrocyclic organic compound in which four pyrrole units are interconnected by methine bridges. Porphyrin plays crucial roles in biological systems, such as binding oxygen in hemoproteins for oxygen transport in blood or assisting in light energy harvesting as a component of chlorophyll in plants. It features a conjugated system composed of 18 π-electrons, resulting in a reduced HOMO-LUMO gap.
