Luminescent multifunctional nanomaterials are important because of their potential impact on the development of key technologies such as smart luminescent sensors and solid-state lightings. To be technologically viable, the luminescent material needs to fulfil a number of requirements such as facile and cost-effective fabrication, a high quantum yield, structural robustness, and long-term material stability. To achieve these requirements, an eco-friendly and scalable synthesis of a highly photoluminescent, multistimuli responsive and electroluminescent silver-based metal-organic framework (Ag-MOF), termed “OX-2” was developed. Its exceptional photophysical and mechanically resilient properties that can be reversibly switched by temperature and pressure make this material stood out over other competing luminescent materials. The potential use of OX-2 MOF as a good electroluminescent material was tested by constructing a proof-of-concept MOF-LED (light emitting diode) device, further contributing to the rare examples of electroluminescent MOFs. The results reveal the huge potential for exploiting the Ag-MOF as a multitasking platform to engineer innovative photonic technologies.

发光多功能纳米材料之所以重要，是因为它们对关键技术（例如智能发光传感器和固态照明）的发展可能产生影响。为了在技术上可行，发光材料需要满足许多要求，例如，简便且经济高效的制造，高量子产率，结构坚固性和长期材料稳定性。为了达到这些要求，开发了一种生态友好且可扩展的高度光致发光，多刺激响应和电致发光的银基金属有机骨架（Ag-MOF）合成，称为“ OX-2”。它具有出色的光物理和机械弹性，可以通过温度和压力进行可逆转换，从而使其在其他竞争性发光材料中脱颖而出。通过构建概念验证的MOF-LED（发光二极管）器件，测试了OX-2 MOF作为良好的电致发光材料的潜在用途，这进一步为电致发光MOF的稀有实例做出了贡献。结果表明，利用Ag-MOF作为多任务平台来设计创新的光子技术具有巨大的潜力。
