A simple strategy for constructing PET fluorescent probe and its application in hypochlorite detection

It is great meaningful to develop a fast and efficient method for detecting hypochlorite (ClO?) owing to its importance in the immune system. In this work, we proposed a strategy to construct fluorescent probes for ClO? based on photoinduced electron transfer (PET) mechanism. According to the strategy, we developed four fluorescent probes named TPA-NO2, TPA-2NO2, TPB-NO2 and TPB-2NO2, and studied their detecting performances for hypochlorite. Among them, TPB-NO2 displayed the most obvious fluorescence changes towards ClO? with a rapid response (2 was successfully used to detect ClO? in living cells and zebrafish. These results demonstrated the feasibility of our strategy and provided a guidance for developing more excellent probes in the future.

Silicon phthalocyanine substituted by trianilino fluoro aryl benzyl ether dendritic ligand and preparing method and application thereof

The invention discloses silicon phthalocyanine substituted by a trianilino fluoro aryl benzyl ether dendritic ligand and a preparing method and application thereof. Firstly, 4'-(diphenylamino)-[1,1'-biphenyl]-4-carboxylic acid is synthesized from 4-bromotriphenylamine and phenylboronic acid, and is then subjected to condensation with hexafluorobisphenol A or bisphenol A respectively to prepare 4-(diphenylamino)-1-biphenylcarboxylic acid-1-carbobenzoxy-1,1,1,3,3,3-hexafluoropropyl phenol and 4-(diphenylamino)-1-biphenylcarboxylic acid-1-carbobenzoxy propyl phenol; and finally, the 4-(diphenylamino)-1-biphenylcarboxylic acid-1-carbobenzoxy-1,1,1,3,3,3-hexafluoropropyl phenol and the 4-(diphenylamino)-1-biphenylcarboxylic acid-1-carbobenzoxy propyl phenol react separately with silicon phthalocyanine dichloride to synthesize bis-(4-(diphenylamino)-1-biphenylcarboxylic acid-1-carbobenzoxy-4-(1,1,1,3,3,3-hexafluoropropyl-4-phenoxy) axially substituted silicon phthalocyanine and bis-(4-(diphenylamino)-1-biphenylcarboxylic acid-1-carbobenzoxypropylphenoxy) axially substituted silicon phthalocyanine. The products can be used as fluorescence imaging agents and photodynamic therapy photosensitizers.

Synthesis of triphenylamine-modified arylates and ketones via suzuki coupling reactions

A series of triphenylamine-mdified arylates and ketones were synthesized via Pd-catalyzed Suzuki coupling reaction of triphenylamine boronic acid with aryl bromide. The triphenylamine boronic acid was synthesized by iodization of 4-bromoaniline, Ullmann reaction of 1-bromo-4-iodobenzene with diphenylamine, and boronic acidification of 4-bromotriphenylamine.
