Special Issue Information

Dear Colleagues,

Luminescent materials and their application in optoelectronic devices are drawing significant research interest owing to their wide application purpose and promising performance. In addition to the traditional luminescent materials such as pure organic dyes, transition metal complexes and rare-earth complexes, many novel luminescent materials have been developed and explored for applications in device construction and sensing, among other applications. For example, metal–organic frameworks (MOFs), covalent organic frameworks (COFs) and porous aromatic frameworks (POFs) have been widely reported. Their large conjugation structure endows them with luminescence features. In addition, their porous structure makes them excellent supporting hosts for other probes and nanoreactors, meaning that these framework materials can be widely developed and explored for versatile purposes. Further research attention has been localized on device construction in order to develop their practical applications, such as optical sensing, phototherapy, molecular sieving, catalysis and photovoltaics.

This Special Issue focuses on novel advances in luminescent materials and devices, including both synthesis and application. The main objective is to highlight the recent progress in luminescent materials and devices with an impact on the design of novel emitters, novel device structures, performance improvement and structural optimization, along with novel applications of these emitters and devices, as well as other relevant topics. Close attention in this Special Issue is paid to reports of novel luminescent materials used for optoelectronic devices and related applications such as optical sensing.

Research and long review papers containing new findings and perspectives on the intriguing field of luminescent materials and devices and their recent applications are welcomed for this Special Issue.

Covalent organic frameworks (COFs) have shown virtues of well-defined and uniform pores with structural diversity, including the shape, size and even chemical nature of pores. These features are excellent for the application of O2 gas optical sensors. In this paper, two oxygen probes based on halogen-bridged Cu cluster were in-situ synthesized in the micropores of COFs, to allow a uniform distribution. The resulting composite samples were characterized in detail to confirm the successful probe loading. The doping level was determined as ~22%. The halogen-bridged Cu clusters showed blue emission peaking at ~440 nm, while COF host showed red emission peaking at 630 nm. These halogen-bridged Cu clusters had long emissive lifetime of ~6.7 μs and high emission quantum yield of 0.30 in pure N2 atmosphere. Given pure O2 atmosphere, lifetime and quantum yield were quenched to 2.5 μs and 0.11, showing oxygen-sensing possibility. A linear oxygen-sensing calibration curve was observed, with sensitivity of 12.25, response time of 13 s and recovery time of 38 s. Sample emission color was changed from blue to red when testing atmosphere was changed from pure N2 to pure O2, which was detectable by eyes. Full article
