摘要: 研究了用溶液滴膜、甘油表面成膜以及溶液旋涂成膜等方法制备的苯封端还原态苯胺四聚体的结晶形态.晶体的晶片厚度、晶体尺寸及结晶完善性均随溶液等温结晶温度的升高而增大.齐聚物在较低过冷度下易于形成尺寸较大的晶体.详细讨论了溶剂及基底与结晶形态的关系.

Abstract: Aseries of crystals of phenyl-capped tetraaniline in the leucoemeraldine oxidation state were obtained with three different preparation methods and were observed directly under transmission electron microscope(TEM). The crystals that crystallized at a higher temperature have a more perfect structure than those at a lower temperature. Both the lamella thickness and the crystal size increase as the isothermal temperatures increase. The oligomer is apt to form a larger scale crystal under a low degree of supercooling. Additionally, the crystal morphology has an important relationship with the kind of substrate on which the oligomer grows, and it will also change with the variation of solvents in which tetraaniline dissolves.

Key words: Tetraaniline, TEM, Crystal morphology, Crystal size
