（1）极性与手性分子晶态材料（Polar&chiral molecular materials ）
极性材料具有极性结构，即由于结构基元的正、负电中心不重合，存在净偶极，产生自发极化。手性材料包含镜像无法与其自身重合的结构单元，在生物标记、手性分析和检测、对映体分离、手性光学、自旋电子学等领域具有重要价值。
我们特别关注其中的铁电、压电和介电功能。其特征在于：电极化可以在外场下进行响应，从而表现出丰富的电、力、光、声、热等方面的性质。其出色的铁电、压电、热释电、非线性光学等性能，可广泛应用于信息存储、探测、成像、能量存储与转换等领域。
Polar materials have polar structures. Because the positive and negative centers of structural units do not coincide, there is a net dipole moment to result in polarization. Chiral materials contain structural units that are non-superimposable on their mirror images, and are of great values in the fields of biomarker, chiral analysis and detection, enantiomer separation, chiroptics, spintronics, etc.
We focus on ferroelectricity, piezoelectricity, and dielectricity of this type of functional materials. They are featured by responses of the polarization upon external electric field, which leads to a wealth of properties. The excellent functions of ferroelectricity, pyroelectricity, piezoelectricity, nonlinear optics, and dielectricity can be widely used in information storage, detection, imaging, energy storage and conversion, etc.
（2）动态响应分子晶体（Dynamic responsive molecular materials）
某些特殊结构的分子晶态材料，对外界激励（光、热、力、化学等）能够发生响应，包括结构相变、物理与化学性质的转变等 。
我们关注的一类响应材料是晶态分子相变体系。其结构当中含有动态基元，能够发生静态-动态的转变，从而引起介电、荧光、晶体外形等性质的变化。对应于介电转变材料、荧光开关、驱动器。该研究可为开关型材料、响应材料提供新的素材，有助于相变材料、介电材料、主客体化学、分子机器等相关研究领域的发展。
Crystalline molecular materials with special structures can respond to external stimuli (light, heat, force, chemistry, etc.), resulting in structural phase changes and property switchings.
One type of the response materials we are concerned about is the phase tranistion molecular crystals. Their structures consist of dynamic components, which can undergo static-dynamic transitions and arouse changes in dielectric, fluorescence, crystal shape and other properties, corresponding to dielectric transition materials, fluorescent switches, actuators and so on. This research can provide new materials for switchable and responsive materials, and contribute to the development of phase-change materials, dielectrics, host-guest chemistry, molecular machines and other related research fields.
