tetraphenylchlorins with two fused indanedione (IND) or malononitrile (MN) groups and two
antipodal Br, Ph, or H β-substituents are investigated in nonaqueous media. These
compounds were synthesized by oxidative fusion of free-base trans-chlorins, followed by
metalation. The corresponding free-base di-fused chlorins were also isolated as
intermediates and characterized for comparisons. The examined di-fused porphyrins (DFP) …
