【摘要】 采用模板法在有机碱DBU的催化下,以4-(2-(2-二乙烯氧基)乙氧基)邻苯二腈及3-(2-(2-二乙烯氧基)乙氧基)邻苯二腈为原料合成了四(α-(2-(2-二乙烯氧基)乙氧基))酞菁铜和四(β-(2-(2-二乙烯氧基)乙氧基))酞菁铜。制备了其旋涂膜,采用紫外可见吸收光谱及原子力对薄膜进行了表征,研究了取代基位置对于酞菁气敏特性的影响,并探讨了四(α-(2-(2-二乙烯氧基)乙氧基))酞菁铜对于含氮类气体NO2、NO、NH3的选择性,结果表明该化合物对NO2的具有较好的选择性。更多还原

【Abstract】 Tetra-α-(2-(2-ethoxyethoxy)ethoxy) phthalocyaninato copper and tetra-β-(2-(2-ethoxyethoxy)ethoxy) phthalocyaninato copper were synthesized from 3-(2-(2-ethoxyethoxy)ethoxy) phthalonitrile and 4-(2-(2-ethoxyethoxy)ethoxy) phthalonitrile by template reaction in the presence of 1,8-diazabicyclo -undec-7-ene(DBU).The thin films were fabricated using spin-coating method.The deposition of phthalocyanine molecules on the substrate was characterized using UV-Vis spectra,and the surface topography was observed using AFM.The effect of the position of the peripheral substituents on the gas sensitivities of phthalocyanines to NO2 was studied.The selectivity of tetra-α-(2-(2-ethoxyethoxy)ethoxy) phthalocyaninato copper film to NO2,NO and NH3 was investigated,and it exhibit the good selectivity to NO2.更多还原
