本文选用一种烷氧基取代的金属酞菁化合物，溶解旋涂于玻璃基板上，分别经有机溶剂处理和加热处理，发现都可以使吸收光谱范围向长波方向拓宽。Ｘ－射线衍射研究表明：经上述方法处理后都可使染料分子的聚集程度发生变化，堆砌方式由微晶型向晶型结构转变，高分辩率扫描电镜观察进一步证实了上述结果。 In this paper, an alkoxy-substituted metal phthalocyanine compound was selected and dissolved on a glass substrate by spin-on treatment with an organic solvent and heat treatment, respectively. It was found that the absorption spectral range can be broadened to the long-wave direction. X-ray diffraction studies have shown that: after the above-mentioned methods can make the degree of aggregation of dye molecules changes, stacking mode from the microcrystalline to crystalline structure changes, high-resolution scanning electron microscopy to further confirm the above results.
