Synthesis And Electronic Properties Of Phthalocyanine With Nitro And Amino Group

Phthalocyanine itself is one has 18лelectronic big link conjugate systems, on the introduction and the phthalocyanine ring-like has the conjugate around the phthalocyanine link the substituting group, has increased the phthalocyanine conjugate scope, enable the phthalocyanine compound often to have in certain structure and the function characteristic, as a result of the conjugate chain growth, their Q belt has not compared with the substitution phthalocyanine, to long wave traverse; B belt broaden, and produces compared to has not substituted for the phthalocyanine strong fluorescence; At the same time, as a result of the benzene ring spatial steric hindrance function, enhanced the phthalocyanine compound solubility, thus can obtain the purity good phthalocyanine, may use in studying the phthalocyanine class compound illumination nature and the optical material aspect. Also has some peripheral by the complex big link conjugate substituting group beautification phthalocyanine class compound, their unique optics, magnetism nature more and more receive people's attention.The phthalocyanine synthesis work is revolving the synthesis substituting group new phthalocyanine, as well as carries on using the widespread function phthalocyanine.As Functional Materials phthalocyanine compound, because had some important uses already to apply in many domains.But the phthalocyanine soluble energy level is bad, causes it to receive many limits in the application, therefore, synthesizes in the organic solvent has the outstanding dissolved performance and becomes the membrane performance the substitution phthalocyanine derivative is the development new phthalocyanine foundation good. Introduces the substituting group to the phthalocyanine link around, enhances the phthalocyanine the solubility to be advantageous to the phthalocyanine depuration, thus enhances the phthalocyanine the utility, is always a phthalocyanine synthesis direction. In recent years the new phthalocyanine synthesis work unceasingly was reported.In view of the fact that above thought, we take obtain the solubility well, the purity good nitryl phthalocyanine as the goal, the design synthesis including metal phthalocyanines and so on nitro-substitution, amino substitution.Uses the neighbouring benzene two nitrile routes, from the precursor compound phthalic anhydride which simple easy to result in embarks, passes through steps and so on Asian amination, nitration, ammonolysis, return to original state, diazonium arylation, the preparation aryl residue substitutes for the neighbouring benzene two cyanines, again passes through and the urea, the metal salt fusing law, the system results in the tetranitro substitution metal phthalocyanine. The nitryl introduction increased the phthalocyanine greatly in the organic solvent solubility, thus easy to obtain the purity high phthalocyanine.In addition, but also synthesized four naphthyloxy cadmium phthalocyanine, the naphthalene oxygen substituting group has been able to increase the metal phthalocyanine compound the solubility to cause it easily to dissolve in some organic solvents, this regarding enhanced the metal phthalocyanine soluble research to have the vital significance. We synthesized the naphthyloxy cadmium phthalocyanine compound in the synthesis research, this naphthyloxy cadmium phthalocyanine compound has the fluorescence nature, and the stability is good, possibly took the photoelectron material, this has the vital significance to the photoelectron material development research.
