Four porphyrinic ionic liquids and four higher melting salts (>100 °C) were synthesized as potential photosensitizers from highly symmetric porphyrins by introducing alkyl chains and exchanging anions to tune their solubility and singlet oxygen generation capability. Among the synthesized compounds was 5,10,15,20-tetra(4-dodecylpyridinum)porphyrin tetrakis-bis(trifluoromethylsulfonyl)-amide, a room-temperature ionic liquid that could be crystallized as a solvate with nitrobenzene.
通过引入烷基链和交换阴离子来调节其溶解性和单线态氧生成能力,从高度对称的卟啉合成了四种卟啉离子液体和四种熔点更高(>100 °C)的盐作为潜在的光敏剂。合成的化合物中有5,10,15,20-四(4-十二烷基吡啶鎓)卟啉四双(三氟甲基磺酰基)-酰胺,一种室温离子液体,它可以与硝基苯形成溶剂化物结晶。
