【摘要】 近些年,超长室温磷光材料(RTP)在照明、显示和成像等领域内有潜在的应用价值,因此受到了研究人员的广泛关注,传统的室温磷光材料主要来自无机磷光材料。在此,我们介绍一种基于金属配位聚合物(CPs)的新型室温磷光材料以及其在传感器方面的应用前景。首先,我们通过水热法合成出两种金属镉的配位聚合物磷光材料,该材料在移除紫外光源后具有超长室温磷光现象(秒级别)。此外,第二种配位聚合物对于pH值和温度展现出良好的磷光可逆响应。因此,本工作提出了一种新型的方法合成配位聚合物室温磷光材料,并通过实验和理论两个方面说明了该方法制备的磷光材料具备性能可调性。此项研究在显示器、pH/温度传感器以及磷光逻辑门等领域内具有应用价值。更多还原

【Abstract】 Ultralong-persistent room temperature phosphorescence(RTP) materials have attracted much attention and present various applications in illumination,displays and bio-imaging fields;however,the persistent RTP is generally from the inorganic phosphor materials to date.Herein,we show that the metal coordination polymers(CPs) could be new types of emerging long-lived RTP materials for potential sensor application.Firstly,two kinds of Cd-based CPs were obtained through a hydrothermal process and the CPs show unexpected second-timescale ultralong-persistent RTP after the removal of UV excitation.Moreover,the CP 2 exhibits well-defined pH and temperature dependent phosphorescence responses.Therefore,this work provides a facile way to develop new type of CPs with steady-state and dynamic tuning of RTP properties from both experimental and theoretical perspectives,which have potential applications in the areas of displays,pH/temperature sensors and phosphorescence logic gates.更多还原
