Spectral manifestation of diacid formation for octalkylporphyrins in fluorescence line narrowing spectra

Abstract

In this work we recorded highly resolved FLN spectra of diprotonated forms of octamethylporphyrin (H[4]OMP{2+}), their meso-deuterated derivative (H[4]OMP{2}+-d4), octaethylporphyrin (H[4]OEP{2+}) and its derivatives with exchanging of central protons on deuterium atoms (D[4]OMP{2+}, D[4]OMP{2+}-d4 and D[4]OEP{2+}) in solid acid solutions at liquid helium temperature
