In the past few decades, porphyrin macrocycles have emerged as a unique class of heterocyclic compounds and as most
5–6 nm when compared to the TPP (Soret band at 419 nm and Q-bands at 516, 551, 590 and 646 nm). In addition, zinc(II) β-triazoloporphyrin–xanthonedyads 6c,f,i exhibited their Soret bands between 430–431 nm and two Q-bands at ~561 and 602 nm which were found to be red-shifted by about 5–6 nm as
