摘要: Four porphyrinic ionic liquids and four higher melting salts (>100 °C) were synthesized as potential photosensitizers from highly symmetric porphyrins by introducing alkyl chains exchanging anions to tune their solubility singlet oxygen generation capability. Among the compounds was 5,10,15,20-tetra(4-dodecylpyridinum)porphyrin tetrakis-bis(trifluoromethylsulfonyl)-amide, a room-temperature liquid that could be crystallized solvate with nitrobenzene.
