5,10,15,20- Four (4- Methoxycarbonylphenyl ) porphyrin (TCMPP) Introduction to

Molecular recognition research is the current coordination chemistry 、 Frontier topics in biochemistry and biomimetic chemistry . The system assembled by non covalent bond interaction simulates the donor of photoreaction center system in natural photosynthesis 、 How receptors bind , To understand and explore the energy transfer in photosynthesis 、 Charge separation, etc , It has attracted people's attention , When there are carboxyl groups around the porphyrin ring of metalloporphyrin compounds 、 hydroxyl 、 Ester group 、 Amino groups and other groups that can form hydrogen bonds , It can be used as a host molecule for molecular recognition of a variety of organic and biological molecules , The traditional method of porphyrin synthesis often needs a long time of heating and refluxing , The speed of organic reaction under the action of microwave is several times ten times or even thousands of times higher than that of traditional methods .

Add... To the round bottom flask 4- Methyl formyl benzoate 1.64g(10mmol),-- A quantitative solvent or catalyst (0.47g Chloroacetic acid catalyst ). Use the three-way pipe equipped with the microwave oven to install the agitators respectively 、 Drip funnel 、 Return line . Microwave radiation under stirring 3min, The liquid in the flask boils before 2min Add pyrrole in the inner drop 10mrol Of 2mL Acetic anhydride ( Because the reaction produces water , Absorption with acetic anhydride ). Continue to heat and stir for a certain time ( Control the microwave power to prevent the reaction liquid from boiling ). Take out the reaction liquid and cool it , Stir and add 20mL In methanol , Let it stand overnight , Suction filtration , Wash the filter cake with methanol ,40C After vacuum drying, it is recrystallized with chloroform methanol , Vacuum dried purple crystals .

In a machine equipped with mechanical stirrer and thermometer 2000mL A three port flask is filled with human propionic acid 1200mL、 nitrobenzene 500mL、 pyrrole 34.6mL、 P-methoxybenzaldehyde 60.7mL, stir , Reflux reaction for two hours ( Reflux temperature 123C) Stop heating after , Cool down naturally while stirring , Cool to 60°C Post filtration , Place the filter cake in a bowl 200mL Three times of methanol washing , dry , Get the product 37.4g, The yield is 40.8%.
