چکیده
|
New thermally stable metallo-phthalocyanines bearing dibenzoxanthenes as highly organo-solubilizing aro- matic hydrocarbon substituents were successfully prepared by cyclotetramerization of corresponding phthalonitriles with anhydrous metal salts [Zn(CH3COO)2 and NiCl2 ] in the presence of a catalytic amount of DBU in 2-(dimethylamino) ethanol. All of these phthalocyanines are soluble in some organic solvents such as DMF, DMSO, THF, CH2 Cl2 , and CHCl3 . Then we successfully prepared the poly(methyl methacrylate) (PMMA)/ZnPc/Al nanocomposite _lms by incorporating Al nanoparticles into a transparent PMMA/ZnPc matrix. The structure and morphology of nanocom- posite _lms were studied using X-ray diffraction and scanning electron microscopy. The optical absorption spectra of PMMA/ZnPc/Al nanocomposite _lms showed red shifting in the Q-band in the polymeric matrix. The geometrical structure of two phthalocyanines was investigated at the RHF/3-21G* computational level.
