New Materials Design.Free-Base Porphyrin and Its Meso-Tetrahalogenated Derivatives
Ab initio electronic structure theory has been applied to predict the structures and electronic spectra of free-base porphyrin (PH2) and its meso-tetrahalogenated derivatives (m-PX8H2, X = F, Cl, Br). Structures, singlet-triplet energy gaps, and electronic [...]
