首次利用对苯二酚与 2 硝基卟啉 ( 1)及其金属配合物直接反应 ,合成了 2 氢醌取代卟啉及其相应金属配合物 :2 ( 2 ,5 二羟基苯基 ) 5 ,10 ,15 ,2 0 四苯基卟啉 ( 5 ) ( 81%) ,2 ( 2 ,5 二羟基苯基 ) 5 ,10 ,15 ,2 0 四苯基卟啉镍 (II) ( 6) ( 61%) ,2 ( 2 ,5 二羟基苯基 ) 5 ,10 ,15 ,2 0 四苯基卟啉铜 (II) ( 7) ( 71%) ,2 ( 2 ,5 二羟基苯基 ) 5 ,10 ,15 ,2 0 四苯基卟啉锌 (II) ( 8) ( 4 1%) ,并利用UV vis、荧光光谱、电化学等方法 ,研究了 2 硝基卟啉 1和 2 氢醌卟啉 5对多种苯醌类衍生物的分子识别 .实验表明5对醌具有较好的识别能力 .

2-(2,5-Dihydroxyphenyl) 5,10,15,20 tetraphenylporphyrin and its nickel(II), copper(II) and zinc(II) complexes 5～8 have been firstly synthesized by direct reaction of hydroquinone with 2 nitro 5,10,15,20 tetraphenylporphyrin and its corresponding metal complexes 1～4, respectively at 240 ℃. The results show that the neutral hydroquinone can react with 2 nitro porphyrin and its metal complexes to yield complexes 5～8 in good yields (81%, 61%, 71% and 41% for 5, 6, 7 and 8, respectively).
