dpdpcb = 1,3-di(2-pyridyl)-2,4-di(3-pyridyl)cyclobutane) through a [2 + 2] cycloaddition reaction. 1a can regenerate into 1 via the cycloreversion reaction based on the thermal effect of sunlight. Such a metal–organic complex exhibits interesting fluorescence switching behavior during the unprecedented fully solar-controlled reversible SCSC reaction, which makes it possible to be applied to the fields
结晶复合物中的可逆共价反应是设计和开发新一代可重复使用智能材料的有力工具。在这项工作中,通过AgNO 3 , 1- _ (2-吡啶基)-2-(3-吡啶基)乙烯(2,3-ppe)和1,3-苯二甲酸(1,3-H 2 bdc)。当暴露在阳光下时,1可以进行单晶到单晶 (SCSC) 转变,形成 [Ag 2 (dpdpcb)(1,3-bdc)] n ( 1a, dpdpcb = 1,3-di(2-pyridyl)-2,4-di(3-pyridyl)cyclobutane) 通过 [2 + 2] 环加成反应。1a可以通过基于阳光热效应的环化反应再生为1 。这种金属-有机络合物在前所未有的全太阳能可控可逆SCSC反应中表现出有趣的荧光转换行为,使其有可能应用于光存储和防伪领域。
