“…Solid-state light emitting materials, especially white light emitting materials, are of particular interest in recent years due to their potential applications in display and lighting. [138][139][140] Li and coworkers designed a ligand H 4 tcbpe 4′,4′′′,4′′′′′,4′′′′′′-(ethene-1,1,2,2-tetrayl)tetrakis ([1,10-biphenyl]-4-carboxylic acid), emitting near 540 nm and coordinated with Zn ion to form LMOFs with high internal and external quantum yields (Figure 13a). [141] The obtained crystals show high surface area and emit near-yellow fluorescence.…”

Inorganic materials functionalized with organic fluorescent molecules combine advantages of them both, showing potential applications in biomedicine, chemosensors, light-emitting, and so on. However, when more traditional organic dyes are doped into the inorganic materials, the emission of resulting hybrid materials may be quenched, which is not conducive to the efficiency and sensitivity of detection. In contrast to the aggregation-caused quenching (ACQ) system, the aggregation-induced emission luminogens (AIEgens) with high solid quantum efficiency, offer new potential for developing highly efficient inorganic-organic hybrid luminescent materials. So far, many AIEgens have been incorporated into inorganic materials through either physical doping caused by aggregation induced emission (AIE) or chemical bonding (e.g., covalent bonding, ionic bonding, and coordination bonding) caused by bonding induced emission (BIE) strategy. The hybrid materials exhibit excellent photoactive properties due to the intramolecular motion of AIEgens is restricted by inorganic matrix. Recent advances in the fabrication of AIEgens-functionalized inorganic-organic hybrid materials and their applications in biomedicine, chemical sensing, and solid-state light emitting are presented.

“…Metal–organic frameworks (MOFs), which are porous materials comprising metal ions and ligands, have attracted much attention for applications such as sensors, crystal sponges, luminescent materials, and soft crystals, and have been also used as cathode active materials in rechargeable batteries . The porous frameworks of MOFs allow one to realize stable battery performances, whereas the dual redox reactions of metal ions and ligands improve the capacity .…”

Porous Metal–Organic Frameworks Containing Reversible Disulfide Linkages as Cathode Materials for Lithium‐Ion Batteries

et al. 2020

Three porous disulfide‐ligand‐containing metal–organic frameworks (DS‐MOFs) and two nonporous coordination polymers with disulfide ligands (DS‐CPs) with various structural dimensionalities were used as cathode active materials in lithium batteries. Charge/discharge performance examinations revealed that only porous DS‐MOF‐based batteries exhibited significant capacities close to the theoretical values, which was ascribed to the insertion of electrolyte ions into the DS‐MOFs. The insolubility of porous 3 D DS‐MOFs in the electrolyte resulted in cycling performances superior to that of their 1 D and 2 D porous counterparts. Battery reactions were probed by instrumental analyses. The dual redox reactions of metal ions and disulfide ligands in the MOFs resulted in higher capacities, and the presence of reversible electrochemically dynamic S−S bonds stabilized the cycling performance. Thus, the strategy of S−S moiety trapping in MOFs and the obtained correlation between the structural features and battery performance could contribute to the design of high‐performance MOF‐based batteries and the practical realization of Li‐S batteries.

“…To achieve the required D–A spectral overlap and study ET processes, we utilized the advantages offered by well‐defined hybrids including modularity and tunability . Based on time‐resolved PL data and theoretical studies of D–A exciton coupling, the ET efficiency and rate, key factors for application development in the field of optoelectronics, were estimated. Thus, the presented studies provide an opportunity to shed light on ET processes in corannulene‐based material for the first time.…”

Hierarchical Corannulene‐Based Materials: Energy Transfer and Solid‐State Photophysics

We report the first example of a donor–acceptor corannulene‐containing hybrid material with rapid ligand‐to‐ligand energy transfer (ET). Additionally, we provide the first time‐resolved photoluminescence (PL) data for any corannulene‐based compounds in the solid state. Comprehensive analysis of PL data in combination with theoretical calculations of donor–acceptor exciton coupling was employed to estimate ET rate and efficiency in the prepared material. The ligand‐to‐ligand ET rate calculated using two models is comparable with that observed in fullerene‐containing materials, which are generally considered for molecular electronics development. Thus, the presented studies not only demonstrate the possibility of merging the intrinsic properties of π‐bowls, specifically corannulene derivatives, with the versatility of crystalline hybrid scaffolds, but could also foreshadow the engineering of a novel class of hierarchical corannulene‐based hybrid materials for optoelectronic devices.
