Synthesis And Supramolecular Assembly Containing Melamine Ring Ttf Derivatives

As the advance of the supramolecular, the novel nanostructure formation, owning special photo-electrical properties, directed at self-assembly is one of the most effective methods. Molecular recognition between the new TTF derivatives containing melamine and barbituric acid, been synthesized, is processed mainly based on the H-bonding force.In this thesis, the main new compounds , 4,5-Bis-(4,6-duchloro[1,3,5]triazine-2-ylsulfanyl)-[l,3]dithiole-2-thione(8) and 2,3,6,7-tetra(4,6-diamine-[1,3,5]triazine-2-ylsulfanyl)-tetrathiafulvalene(10), have been synthesized, which structure were certified by 1HMR, elemental analysis, IR, MS, et al .The compound (8) contains both tetra-[1,3,5-triazine], a good electro-donor groups, and the TTF structure, as a Rigid framework, difficult in deforming, has good fluorescence property. Comparison to (8), the fluorescence intensity of compound (10) is poor as the extend of amine conjugated to triazine stronger than that of chlorin to triazine. The electrochemical behavior studied the relation between structure and function. The spectrum of every compound were tested for the properties in different concentration.The resolve ability of barbituric acid derivatives (22) has been improved as being connected to a long alkyl, which is now easily dissolved in Chloroform. The procession of self-assembly in low-polarity solvent is possible.Molecular recognition between (8) and (22) in Chloroform has been confirmed in details by analysising the spectrum of UV-Vis, Fluorescence and IR.
