  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.
