5- (4-nitrophenyl) - 10,15,20-triphenylporphyrin ntpph2/ntppzn/ntppmn/ntppfe/ntppni/ntppcu/ntppcd/ntppco and other metal complexes

5-(4- Nitrophenyl )-10,15,20- Triphenyl porphyrin NTPPH2/NTPPZn/NTPPMn/NTPPFe/NTPPNi/NTPPCu/NTPPCd/NTPPCo And other metal complexes

In neutral phosphate buffer solution , With ultraviolet - Water insoluble porphyrins were studied by visible spectrophotometry and fluorescence spectrometry 5-(4- Nitrophenyl )-10,15,20- Triphenyl porphyrin (NTPPH2) and 5-(4- Aminophenyl )-10,15,20- Triphenyl porphyrin (ATPPH2) And α-CD、β-CD and γ-CD Supramolecular system formed by the interaction of three cyclodextrins . It turns out that ,NTPPH2 And α-CD、β-CD and γ-CD Have formed 1:1 Inclusion of ,ATPPH2 And β-CD formation 1:2 Inclusion of , And α-CD and γ-CD Then it forms 1:1 Inclusion of . among α-CD And NTPPH2 and ATPPH2 The inclusion constant of is large . In this paper, the influence of electron donating group and electron absorbing group on the inclusion of porphyrin ring is discussed , It provides a basis for the study of the interaction between porphyrin and cyclodextrin and the mechanism of supramolecular system .

To tetraphenylporphyrin （TPPH2） The preparation of

Tetraphenyl porphyrin was synthesized , Go to 250mL Equipped with magnetons 、 Add

80mL Propionic acid ,12mL Benzaldehyde , Heat with magnetic stirring until refluxing . Slowly add and dissolve 4mL Propionic acid solution of pyrrole 15mL Into the reaction bottle ,30min Add in . Continue reflux reaction 40mi about , Stop heating . Let it cool to 40℃, Join in 60mL Absolute ethanol , Put it on ice and freeze overnight . The reaction solution was filtered with absolute ethanol to obtain tetraphenylporphyrin （TPPH2） Purple crystal 3.856g, Yield 27.8％.

Four (4- Nitrophenyl ) porphyrin （TNPPH2） The preparation of

take 80mL Nitrobenzene and 28mL Lactic acid is added to 250mL In three mouth bottle , Under reflux stirring ,20min Internal dropping 60mL Dissolve 8.00g(53mmol) P-nitrobenzaldehyde and 3.60mL（51mmol） Nitrobenzene solution of pyrrole , Keep reacting 2h. Add after slightly cooling 60mL Anhydrous methanol , stir 30min, Let it stand overnight . Filter the reaction solution , Separate solids ,40℃ After vacuum drying, the crude product is obtained . Then dissolve it in pyridine and recrystallize , After filtration, purple four (4- Nitrophenyl ) porphyrin （TNPPH2） Crystal 9.02g, yield 21.4%.
