研究了溶剂蒸气对多晶型酞菁衍生物旋涂薄膜的影响。单晶薄膜的生长，通过溶剂蒸气下再溶解的有机膜揭示了薄膜的原位显微镜观察。X-射线衍射测量暴露于溶剂蒸气后的膜揭示了溶剂蒸气下的多晶型物的相变。通过测量生长的单畴膜中的晶体取向来澄清晶体生长的方向。根据多晶型物溶解度的不同，讨论了溶剂蒸气复溶有机薄膜晶体生长的机理。(C)2015年作者。
The effects of solvent vapor on spin-coated films of a polymorphic phthalocyanine derivative were investigated. Growth of single crystal films via redissolving organic films under solvent vapor was revealed by in situ microscopic observations of the films. X-ray diffraction measurement of the films after exposing to solvent vapor revealed the phase transition of polymorphs under solvent vapor. The direction of crystal growth was clarified by measuring the crystal orientation in a grown monodomain film. The mechanism of crystal growth based on redissolving organic films under solvent vapor was discussed in terms of the different solubilities of the polymorphs. (C) 2015 Author(s).
