The acceptor-porphyrin cyclophanes 2 and 4 with pyromellitic diimide (1) as strong electron-acceptor, and the corresponding porphyrin zinc complexes 3 and 5 were prepared by a route which differs considerably from that in the syntheses of previously prepared electron-acceptor porphyrin cyclophanes. The conformations of these electron-acceptor-porphyrin cyclophanes are discussed based on 1H-NMR and
以均苯四甲酸二亚胺 (1) 作为强电子受体的受体-卟啉环烷 2 和 4 以及相应的卟啉锌配合物 3 和 5 的制备路线与先前制备的电子受体卟啉环烷的合成路线大不相同. 基于1H-NMR和2的X射线结构分析讨论了这些电子-受体-卟啉环烷的构象。根据所得结果,1的平面和卟啉单元的平面(至少处于结晶状态) ) 彼此既不接近也不平行。2 检测到供体和受体平面的异常二面角取向。
