Abstract
The novel watersoluble and sterically hindered phthalocyanine complexes ie ironIII tetra4carboxyphenoxyphthalocyanine 3 and ironIII tetra8quinolineoxy5sulfonicacidphthalocyanine 4 were synthesized for fast detection of phenolic pollutants These two FePc complexes exhibited the high catalytic activity in the chromogenic reactions of phenolic pollutants Five phenolic substrates including phenol 2chlorophenol 4chlorophenol 24dichlorophenol and 1naphthol could be efficiently oxidized by tertbutyl hydroperoxide in the presence of these selected FePc catalyst UV–Vis spectroscopy and HPLC technique were used to monitor the catalyzed oxidation of phenolic substrates Compared with catalytic methods by other reported phthalocyanines this system has the obvious advantages of fast oxidation and highyield conversion of phenolic substrates Under the optimal conditions the chromogenic process of 2chlorophenol could be completed just within 10 min with more than 90 of conversion Potentially this system is promising for the application of fast chromogenic identification of phenolic pollutantsThis work was financially supported by the National Natural Science Foundation of China Nos 61377092 and 51302241 the Fundamental Research Funds for the Central Universities WUT 2013IV010 the Science and Technology Key Project of Education Department of Henan Province No 13B430233 and No 13A150743 We thank professor Yu Cao College of Chemistry Huazhong Normal University for the help of chemical characterization and measurement We thank MSc Shilong Zhao School of Materials Science and Engineering Wuhan University of Technology for the help of purification of two novel watersoluble iron phthalocyanines
