Stellate macroscopic crystals from cationic and anionic porphyrins
Mixing tetrasodium [meso-tetrakis(4-sulfonatophenyl)porphinato]zinc (Zn-TSPP) and meso-tetrakis(4-(trimethylammonio)phenyl)porphine tetratosylate (TTMAPP) in dimethylsulfoxide leads to formation of a star-like (stellate) microcrystal.
