【摘要】 光致变色材料在民用、军事和空天等多个领域具有非常重要的实际或潜在应用价值,相关研究是当今科学技术领域的前沿和热点课题之一。通常情况下,有机光致变色材料具有可修饰性高、颜色丰富、光响应速度快等优点,但是大部分不耐高温而且容易疲劳;无机光致变色材料具有热稳定性高和耐疲劳性能好等优点,但是数量很少而且普遍消色慢。开发新型的有机或无机光致变色体系己较为困难。结合无机和有机的优点研发新型的无机-有机杂化光致变色材料体系成为当前的一个重要发展趋势。我们研究组在无机-有机杂化光致变色材料方面取得了系列研究成果,如在金属卤化物光致变色杂化材料体系和过渡金属-有机配合物光致变色材料体系的研究方面,首次用结构化学方法研究了光致变色材料变色前后的结构变化,结合多种物理性能测试和量化计算的研究结果揭示了光致变色现象与结构变化的关系,深入地研究了这类光致变色材料体系的光致变色机理^[1-7]。更多还原

【Abstract】 One of the interests of current science and technology is in the development of photochromic materials,for their real or potential applications in civil use,military,aerospace,and other areas.Generally,the former features the ability of being chemical modified,rich colors,and fast response time to light;however,most of them are not high-temperature and fatigue resistant.Inorganic photochromic materials have considerable thermal stability and good fatigue resistance,but they usually have limited variety and fade slowly.It has been difficult to develop new types of organic or inorganic photochromic materials.One of the important issues in the photochromic field is to seek new photochromic materials through the inorganic-organic hybridation strategy.Our group had made a series of research achievements on inorganic-organic hybrid photochromic materials,such as photochromic metal-halide hybrids and metal-organic complexes.We first determined the crystal structures of these materials before and after irradiation,revealed the relationship between photochromic phenomenon and structural change through diverse physical determinations and theoretical calculations,and probed the mechanism of photochromism.更多还原
