Space- and time-resolved emission features of micro- and nano-sized perylene-based Zr metal-organic frameworks (dataset)

While many photoresponsive metal‒organic frameworks (MOFs) have been reported to date, finding applications in several technologically relevant fields such as photocatalysis, sensors, and light-emitting devices, significantly scarcer are the reports addressing the relationship between the MOFs emissive features and their crystalline domain size (i.e., micro- and nano-sized materials). Herein, a valuable contribution is offered to this issue which consists of the use of reticular chemistry to prepare a Zr-MOF featuring spatially separated tetracarboxylated-functionalized perylenes as ligand. Single crystal X-ray analysis of such Zr-MOF revealed the formation of micro- and meso-porous channels. The perylene-based Zr-MOF exhibited notable optoelectronic features, including a relatively small optical bandgap of 1.82 eV and emission features different from that of the constituting perylene ligand in the solid state. Additionally, local probe techniques are used to unveil the emission properties of isolated Zr-MOF crystals. Space- and time-resolved fluorescence studies revealed a strong dependence of the emissive features of the Zr-MOF, both in terms of its intensity and lifetime, to the crystalline domain size.

迄今为止，尽管报道了众多光响应金属-有机框架（MOFs）在光催化、传感器和发光器件等众多技术相关领域的应用，但关于MOFs发射特性与其晶体域尺寸（即微纳米尺寸材料）之间关系的报道却相对罕见。本文对此问题作出了宝贵贡献，其中采用网状化学方法制备了一种含有空间分离的四羧基化功能化芘作为配体的Zr-MOF。通过单晶X射线分析，揭示了该Zr-MOF形成了微孔和中孔通道。基于芘的Zr-MOF展现出显著的光电特性，包括相对较小的光学带隙1.82 eV以及与固态中构成配体的芘不同的发射特性。此外，通过局部探针技术揭示了孤立Zr-MOF晶体的发射性质。空间和时间分辨荧光研究表明，Zr-MOF的发射特性，无论是其强度还是寿命，均强烈依赖于晶体域尺寸。化合物表征（原始数据）。本文的补充材料可参考doi:10.1002/adom.202402127。
