Research On Chemical Sensors As Well As Applications As INHIBIT Logic Gates Based On Organic-Metal Complexes

As we all known, anion plays an important role in the field of chemistry, biology and environment. The method of detecting and recognizing anions is a hot research field. With the development of supramolecular chemistry, chemical sensor is widely used in anions detection because of the characteristics such as smart, high sensitivity, wide range of measurement, low price and easy automation. Colorimetric chemical sensor as a kind of chemical sensor can detect anions by "naked eye" without other instruments. In this paper, we used TAC as ligand which belongs to thiazole azo dyes and synthesis a variety of organic-metal complexes. The features of organic-metal complexes were used to detect anions. The main content of this paper is as follows:1. A brief introduction to the development of supramolcular, the composition of photochemical sensor, the organic-metal complexes of photochemical sensors, anions colorimetric chemical sensors and the research progress of molecular logic gate.2. Design and synthesis TAC-Ni2+ complex as colorimetric chemical sensor to detect CN-. When the TAC-Ni2+ complex detecting CN-, it can overcome the interference of other anions. This complex is a good colorimetric chemical sensor with low limit of detection and high sensitivity.3. Design and synthesis TAC-Cu2+ and TAC-Co2+ organic-metal complexes. These two complexes can combine used to detecting CN- by the different color response to anions.4. Utilization of metal ions and anions (or H+) as the input signals and the absorbance intensity changes as the output signal. Design a variety of INHIBIT logic gates based on TAC system. The applications of molecular logic gate in the supramolecular field come true.
