The present study has been carried out for the purpose of establishing the fundamentals to develop a low-temperature synthesis and morphology control method for inorganic functional materials which is based on the molecular recognition phenomena at the inorganic-organic interfaces. Hydroxyapatete, magnetitie, and AgCl crystals were grown under Langmuir monolayrs of various surfactant molecules, and metals such as Bi, Zn, and Sn were vapor-deposited on the Langmuir-Blodgett (LB) films with either hydrophilic or hydrophobic surfaces. Apatite and AgCl were both grown under the monolayrs with their specific crystallographic planes aligning parallel to the monolayrs due to their simple growth reactions, while magnetite films grown exhibited no such preferred orientation possibly because of the complicated reaction process. Molecular recognition was found to be effective for controlling the inorganic morphology even in a dry process where only weak interface interactions can be utilized ; large oriented crystals were grown on the hydrophobic surface. The results obtained in the present study firmly indicate a promising future for biomimetic materials synthesis and morphology control.

本研究的目的是为开发基于无机-有机界面分子识别现象的无机功能材料的低温合成和形貌控制方法奠定基础。羟基磷灰石、磁铁矿和 AgCl 晶体在各种表面活性剂分子的 Langmuir 单层下生长，Bi、Zn 和 Sn 等金属气相沉积在具有亲水或疏水表面的 Langmuir-Blodgett (LB) 薄膜上。由于生长反应简单，磷灰石和AgCl都在单层下生长，其特定的晶面平行于单层排列，而磁铁矿薄膜则没有表现出这种择优取向，可能是因为反应过程复杂。研究发现，即使在只能利用弱界面相互作用的干法工艺中，分子识别也能有效控制无机形态。大的定向晶体生长在疏水表面上。本研究获得的结果有力地表明了仿生材料合成和形貌控制的广阔前景。
