单分子膜诱导下晶体生长中的晶格匹配

有机基质与无机晶体的晶格几何匹配是导致生物体内矿物有序生长并具有特殊理化性质的重要因素之一.作为模拟生物矿化的重要模板之一,Langmuir单分子膜具有独特的优势.本文综述了单分子膜诱导下CuSO4、Na2SO4、PbS、CdS、BaF2和CaF2等晶体生长过程中的晶格匹配,讨论了单分子膜亲水头基、膜的电荷性质、膜聚集态等因素对膜控晶体生长过程中晶格匹配的影响.指出了该领域所面临的问题和将来的发展方向.

Lattice Matching in Crystal Growth Induced by Monolayers

Lattice geometrical matching is one of the most important factors in leading to the oriented nucleation and in affecting the physical and chemical properties of biominerals.As an important template of mimicking biomineralization,Langmuir monolayers have special advantages.In this paper,the research progress in lattice geometrical matching was reviewed to inorganic crystals CuSO_4,Na_2SO_4,PbS,CdS,BaF_2,and CaF_2,etc.The effects of hydrophilic headgroups,charges and the aggregated states of monolayers on lattice geometrical matching at the inorganic/organic interfaces were discussed.The problems faced with and the developing direction were also indicated.
