摘要
以二价钴为模板采用原位合成的方法在SnO2凝胶基质合成的同时,通过萘氧基取代的邻苯二腈的四聚反应将β-四萘氧基酞菁钴在SnO2表面原位合成,得到β-四萘氧基酞菁钴/二氧化锡,并且利用UV、IR、XRD和TG对产物进行表征。结果表明:β-四萘氧基酞菁钴/二氧化锡的紫外光谱图中出现了酞菁特征吸收Q带的红移;红外光谱中出现了M-O的振动吸收峰以及在XRD测试中SnO2晶粒变小,都表明β-四萘氧基酞菁钴与二氧化锡之间形成部分化学键。
β-Treanaphththalen-2-oxy-metal phthalocyanine cobalt/SnO2 nanocomposite was synthesized in-situ through the annulation of 4-hydroxy-phthalonitrile with 2-methyl-naphthalene on the surface of SnO2 nanoparticles while the SnO2 gel base was formed with Co(Ⅱ) as template.The prepared products were characterized by means of UV、IR、XRD and TG methods.The experimental results indicated that on the UV spectrum of the product the characteristic absorption Q belt moved to long wavelength;the vibration absorption peaks of M-O appeared on IR spectrum,and on XRD pattern the size of crystal particles became smaller than before.All these showed that in the complex β-treanaphththalen-2-oxy-metal CoPc and SnO2 were linked with partial chemical bond.
