The improved Adler's method was used to prepare the complexes of tetraphenyl (2-nitro-) porphyrinstometal (abbreviation TP(2-NO_2)P·M). The structures and compositions of the complexes were determined by elemental analysis, UV, IR, ~1H NMR and EPR. Adducts of the complexes with nitrogen-containing organic bases were studied by spectroscopic titration method.

The metal Complexes coordinated with tetrapbenyl porphyrin and tetraphenyl-2-nitroporphyrin were investigated by XPS. These metal complexes in which ions were mosaiced into big ? system of conjugated ring structrue were demonstrated by π→π* transition energy, transition probability and Nlt shift of binding energy. Furthermore, it was proved that -NO3 group is in conjunction with a pyrrole ring and this leads to an increase of Lewis acidity.

用XPS研究了四苯基(2-硝基)卟啉及其过渡金属化合物。由π→π跃迁能、跃迁几率及N_(1S)和金属M_(2p3/2)结合能的位移证明,这些化合物是金属镶嵌在大π体系共轭环中而成的金属配合物。其中,—NO_2是连在卟啉环上。引入—NO_2后,金属结合能升高,Lewis酸性增强,因而与轴向配位体的加合能力增强。

An important compound of 3,3′,4,4′-tetramethyl-2,2′-dipyrrolylmethane (TMDPM, 6) was synthesized through multi-step-reaction starting from 3-methyl-2,4-dipentadione. Therein, the reaction for converting 3,3′,4,4′-tetramethyl-2,2′-dipyrrolylmethane-5,5′-dicarbonate(5) to TMDPM was improved by substituting hydrazine with ethanolamine as decarboxylation agent. The synthesis of meso-15,15-bis-phenyl-porphyrin by dipyrrolylmethane procedure was investigated. It was found that p-toluenesulfonic acid was the efficient catalyst for condensation of compound 6 with nitrobenzaldehyde to porphyrinogen (7), and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone(DDQ) was effective reagent for oxidizing of compound 7 to nitroporphyrin. After the hydrogenation of nitro-groups by SnCl 2/concentrated HCl system to amino-groups, the extraction of the resulted aminoporphyrin by solid-mixture/chloroform process conducted better effects than aqueous-mixture/chloroform process. Following the methods aforesaid, several new porphyrin compounds including 5,15-bis(4-nitrophenyl)- 2,3,7,8,12,13,17,18-octamethyl-porphyrin(BNPP, 8),5,15-bis(4-aminophenyl)-2,3,7,8,12,13,17,18-octamethyl-porphyrin(BAPP, 9) and metal-BAPP were synthesized. Their structures and absorption properties were characterized as well.
