首次使用简单的合成策略设计和制造了一种基于光致发光功能化（PL）相变材料（PCM）的新型金属有机框架（MOF），以实现卓越的热能和荧光捕获，从而扩展了具有新颖荧光功能的 PCM 的传统单热性质。将硬脂酸（SA）和碳量子点（CQD）分子同步纳入Cr-MIL-101-NH2骨架中，其中MOF骨架作为理想的相容支撑主体，CQD作为优异的荧光客体，硬脂酸作为优异的热能客体。我们独特构建的 MOF 参与的 PCM 在 CQD 的辅助下有效地防止了操作过程中传统的聚集诱导的荧光猝灭。这种新颖的有针对性的功能策略创建了一个创新平台，用于开发具有多种迷人特性和所需特性的先进多功能PCM，可普遍应用于其他多功能MOF主机和其他功能客体，以扩展基于MOF的PCM的应用并开发具有多种增强功能特性的模块化设备。
A novel type of metal-organic frameworks (MOFs) based photoluminescence-functionalized (PL) phase change materials (PCMs) was designed and fabricated for superior thermal energy and fluorescence harvesting using a facile synthetic strategy for the first time, which expands conventional single thermal nature of PCMs with novel fluorescence function. Stearic acid (SA) and carbon quantum dot (CQD) molecules were synchronously incorporated into the Cr-MIL-101-NH2 framework, in which MOF framework serves as an ideal compatible support host, CQD as a superior fluorescent guest, and stearic acid as an excellent thermal energy guest. Our uniquely constructed MOF-involved PCMs assisted by CQDs effectively preclude conventional aggregation-induced fluorescent quenching during the operation. This novel targeted functional strategy creates an innovative platform for developing advanced multifunctional PCMs with multiple fascinating peculiarities and desired properties, which can be universally applied to other versatile MOF hosts and other functional guests for expanding the applications of MOF-based PCMs and developing modular devices with multiple enhanced functional properties.
