Synthesis and spectroscopy properties of transition metal phthalocyanine complexes

以环保型的煤油为溶剂,采用苯酐尿素法合成了钴酞菁(CoPc)、铜酞菁(CuPc)、锌酞菁(ZnPc)、锰酞菁(MnPc)等几种具有鲜艳色泽的过渡金属酞菁配合物.在室温下,通过红外光谱(IR)、紫外可见吸收光谱(UV-Vis)和荧光发射光谱对产物进行了表征和光物理性质测定研究,并对各光谱进行了分析指认.重点研究了中心金属离子和配合物的聚集态对紫外可见吸收光谱和荧光发射光谱的影响,结果表明,金属离子的原子序数和电负性以及配合物的聚集态对产物的光学性能有较大的影响.此外,热重分析表明,该系列化合物开始分解温度高达500℃,具有良好的热稳定性.

Taking the mixtures of benzene anhydride and urea as the raw materials,and the kerosene as the environmentally friendly solvent,a series of transition metal phthalocyanine complexes with excellent properties of bright color were synthesized,including cobaltous phthalocyanine,cupric phthalocyanine,zinc phthalocyanine and manganese phthalocyanine.The infrared spectroscopy,UV-Vis and fluorescence measurements of the target products were performed.The effects of central metal ions and aggregation of complexes were also studied.The results show that the atomic number and electronegativity of central metal ions have great influences on the spectroscopy performance.Moreover,these coordination compounds have good thermal stability above 500 ℃ by TG.Environmentally friendly synthesis of metal phthalocyanines were achieved.
