＜正＞Bio-inspired smart materials should be a “live” material with various functions like organism in nature,they must have three essential elements as sense,drive and control. The putting forward of bio-inspired smart interfacial materials just bases on the above mentioned elements,while the design principle can be divided into five levels:（1）

2003年纳米和表面科学与技术全国会议

作者： Lei Jiang center of molecular sciences, institute of chemistry, Chinese Academy of sciences, Beijing 100080, China

The wettability of solid surfaces is a very important property, and is governed by both the chemical composition and geometrical microstructure of the surface. The generation by UV illumination of a super-hydrophilic TiO2 surface with a contact angle (CA) for water of 0°has attracted significant attention. This material has already been successfully applied as a transparent super-hydrophilic coating with antifogging and self-cleaning properties. Currently, super-hydrophobic surfaces with water CA higher than 150°are arousing much interest because they will bring great convenience in daily life as well as in many industrial processes. Various phenomena, such as snow sticking, contamination or oxidation, and current conduction, are expected to be inhibited on such a surface.

＜正＞The wettability of solid surfaces is a very important property, and is governed by both the chemical composition and geometrical microstructure of the surface. Currently, super-hydrophobic surfaces with water CA higher than 150°are arousing much interest because they will bring great convenience in daily life as well as in many industrial processes. Various phenomena, such as snow sticking, contamination or oxidation, and current conduction, are expected to be inhibited on such a surface. Conventionally, super-hydrophobic surfaces have been produced mainly in two ways. One is to create a rough structure on a hydrophobic surface, and the other is to modify a rough surface by materials with low surface free energy. While the water CA has commonly been used as a criterion for the evaluation of hydrophobicity of a solid surface, this alone is insufficient to assess the sliding properties of water droplets on the surface. A fully super-hydrophobic surface should exhibit both high CA and low sliding *** recent studies on lotus and rice leaves reveal that a super-hydrophobic surface with both a large CA

中国化学会第四届有机化学学术会议

作者： Deqing Zhang, Xuefeng Guo, Yucheng Zhou, Guanxin Zhang, and Daoben Zhu Organic Solids Laboratory, center for molecular sciences, institute of chemistry, Chinese Academy of sciences, Beijing 100080, China

＜正＞It is well known that the reversible structural interconversion between different states of spiropyrans can occur in response to external optical, chemical, and thermal stimulations, accompanied with the substantial changes of their photophysical and photochemical properties. By taking these particular properties of spiropyrans, new combinational logic circuits and even signal communication between molecules have been described. In this presentation, I will describe: （1） modulation of the fluorescence of new dyads with fluorescence and spiropyran units upon light irradiation and the action of ferric ion. Such fluorescence variation mimics the behaviors of logic gates and circuits;（2） "intermolecular signal communication" between spiropyran and 1-aminomethylpyrene/ and a bis-pyrene molecule through proton transfer /and energy transfer in the presence of Zn2+;（3） coordination of the open form of spiropyran with Fe2+ and Fe3+ and the modulation of redox potential of Fe2+/Fe3+. This property of spiropyran was used to photo-control the electron transfer between tetrafulvalene/fluorescein and Fe3+;（4） a new chiral molecular switch based on binaphthanol with two spiropyran units;（5） modulation of the thin film conductivity of polyaniline containing spiropyran.
