| 中文摘要 | control of crystal polymorph and size is very important in many application fields. herein we demonstrate that langmuir-blodgett (lb) films of stearic acid (sa) and octadecylamine (oda) can serve as templates and generate different polymorphs of glycine crystals. in the neutral aqueous solutions, gamma-glycine crystallizes on lb films of oda while the polymorphic outcome becomes the (x-form on lb films of sa. these observed results could be explained by the electrostatic interactions and geometric lattice matching at the lb film/crystal interfaces, respectively. by keeping the appropriate supersaturation, we have successfully controlled the number of crystals grown on lb films; for example, in some certain cases, only one piece of crystal was grown on lb films in solution. therefore, large crystals of centimeter size could be prepared. these experimental results suggest a new approach to produce an organic crystal with bulk scale. |
