用三氟乙酸处理可以诱导卟啉-苝酰亚胺二元染料分子聚集状态的变化.在透射电子显微镜下观察发现,从中性溶剂中沉析出的固体的微观形态呈片状,而经酸处理后形态转变为球状纳米粒子.X射线衍射图谱表明,片状形态的固体为多晶,而经酸处理后转变为无定形固体.选择适当的参照物为依据,通过对紫外-可见吸收光谱性状变化的仔细分析发现,在由中性溶剂得到的微粒中卟啉和苝酰亚胺基元均采取J-聚体的方式排列;而在经酸性溶剂处理后得到的微粒中,苝酰亚胺基元排列成H-聚体而卟啉基元呈无规则排列.
Trifluoroacetic acid treatment can induce the aggregation of porphyrin-perylene imide binary dye state changes observed under a transmission electron microscope found that the solid precipitated from a neutral solvent microscopic morphology flake, and acid treatment X-ray diffraction pattern shows that the flaky morphology of the solid is polycrystalline, and after acid treatment into an amorphous solid.On the basis of selection of the appropriate reference, through the UV-Vis absorption spectroscopy A careful analysis of the change revealed that the porphyrin and the perylene imide units were all arranged in a J-mers in the microparticles obtained from the neutral solvent, and among the microparticles obtained after the acidic solvent treatment, the perylene imide Motifs are arranged in H-mers and porphyrin motifs are randomly arranged.
