π共轭有机发光体是现代光电子学的基本成分之一。本文简要介绍了近年来基于氰基芪及其衍生物的一类智能π共轭体系的研究进展，该体系的物理化学性质可以根据各种外界刺激（如极性、粘度、pH值、光和热的变化）进行调节。为了充分利用氰基二苯乙烯及其衍生物独特的可调特性，将其植入聚合物、溶胶-凝胶体系、固体薄膜、超分子结构、功能纳米粒子等领域，本文综述了氰基二苯乙烯及其衍生物杂化材料的制备和表征方法，并重点介绍了其独特的功能，如AIEE等（聚集诱导的增强发射）效应、固态发射、光致变色、光致发光和生物成像。最后对氰基芪类智能材料的应用前景进行了展望。基于氰基芪的智能混合物的蓬勃发展预示着新一代的集成多功能材料，这一结果对于开发与物理学，材料化学，生物学和医学科学相结合的响应材料至关重要。
pi-Conjugated organic luminophores are one of the essential ingredients for modern optoelectronics. This short review highlights recent research progress on a type of smart pi-conjugated systems based on cyanostilbene and its derivatives, in which their photophysical properties can be tuned in response to a variety of external stimuli (e.g. polarity, viscosity, pH, light and thermal changes). To take advantage of the unique tunable features, cyanostilbene and its derivatives have been implanted into polymers, sol-gel systems, solid films, supramolecular architectures, functional nanoparticles, and so on. In addition to discussing the preparation and characterization of cyanostilbene-based hybrid materials, this review highlights their charming functionalities, such as AIEE (aggregation-induced enhanced emission) effect, solid-state emission, photochromism, photovoltaics, and biological imaging. Future studies on the applications of cyanostilbene-based intelligent materials are also predicted. The blossoming of cyanostilbene-based intelligent hybrids promises a new generation of integrated multifunctional materials, an outcome which is essential for the development of responsive materials that interface with physics, materials chemistry, biology, and medical science.
