Embodiment 1

[0074] A 3 Preparation of B-type monomercapto porphyrin H2TCLPP-(SH)1:

[0075] (1)H 2 TClPP-(COOH) 1 Preparation of:

[0076] Mix p-chlorobenzaldehyde (7.0g, 0.050mol), p-formylbenzoic acid (1.5g, 0.010mol) and 200mL propionic acid, stir to dissolve, heat to reflux (145°C), and mix 50mL propionic acid and pyrrole ( 4.5mL, 0.065mol) was added dropwise to the mixture, and continued to reflux for 0.5h after the dropwise addition.

[0077] Then, cool to room temperature naturally, add 200mL methanol / water mixed solution (V 甲醇 :V 水 =95:5), placed in the refrigerator overnight.

[0078] Finally, filter with suction, wash the filter cake with water and methanol until the filtrate is light red, and dry naturally. The product is firstly separated by silica gel column chromatography with dichloromethane as eluent, and the first product collected is tetrachlorophenylporphyrin H 2 TClPP. Then use dichloromethane instead: anhydrous methanol=10:1 as eluent, separate by silica gel ...

Abstract

The invention relates to the field of functional coordination compounds, and concretely relates to an A3B type monothiol porphyrin compound as well as a preparation method and application thereof. Themonothiol porphyrin compound prepared through the method provided by the invention has a strong coordination ability; the compound and UiO-66 is synthesized through a post-modification synthesis method so as to prepare a frame nanometer material modified by monothiol porphyrin, i.e., UiO-66-H2TC1PP-(SH)1. The UiO-66-H2TC1PP-(SH)1 prepared by the invention can well solve the problems that a porphyrin molecular compound in the prior art is insoluble in water, easy to agglomerate and poor in stability, so that the quantum yield, the fluorescent lifetime and a light sensitive characteristic of singlet oxygen of porphyrin and derivatives thereof are greatly improved.

Description

technical field [0001] The invention relates to the field of functional complexes, in particular to a kind of A 3 B-type monomercapto porphyrin compound and its preparation method and application. Background technique [0002] Porphyrin compounds are a class of macrocyclic conjugated molecules that widely exist in nature and have special physiological activities. Chlorophyll and heme are typical representatives, and they both play important roles in organisms. The artificially synthesized porphyrin molecules are mainly substituted at the meso-position (middle position) by various types of functional groups, and the number and arrangement of substituent groups are various. They can be simply divided into symmetrical porphyrin compounds and asymmetric porphyrin compounds. At present, the meso-position of the reported asymmetric porphyrin compounds is mainly composed of two different substituent groups (represented by A and B), which are divided into AABB, ABAB and A 3 Type B...
