Host–guest Metal–Organic Frameworks-Based Long-Afterglow Luminescence Materials

Molecules, Год журнала: 2024, Номер 29(13), С. 2989 - 2989

Опубликована: Июнь 23, 2024

Long-afterglow materials have a broad of applications in optoelectronic devices, sensors, medicine and other fields due to their excellent luminescent properties. The host-guest long-afterglow MOFs material combines the advantages multi-component characteristics stability MOFs, which improves its luminous performance expands This review introduces classification, synthesis application with long afterglow. Due rigid frames multi-channel characteristics, can load common guest including rare earth metals, organic dyes, carbon dots, etc. methods loading into include solvothermal synthesis, post-encapsulation, post-modification, Those wide range information security biological imaging.

Wide-Range Excitation-Dependent Phosphorescence of Coordination Polymers Exhibiting Dynamic Anticounterfeiting, White-Light Emission, and Antibacterial Performance

Inorganic Chemistry, Год журнала: 2024, Номер 63(35), С. 16284 - 16292

Multicolor-tunable room-temperature phosphorescence (RTP) is attracting wide attention in optoelectronic applications. Here, we propose a coordination-oriented assembly approach to achieve wide-range RTP with benzimidazole derivative (2,7-diazabenzimidazole, DZBIM) as luminogen. These two compounds exhibit unexpected excitation-responsive emission, and the emission nearly covers entire visible region change of excitation wavelength from 360 620 nm. To best our knowledge, this first report coordination polymers such full-color-tunable RTP. Compound 1 also shows white-light upon at 280 Experimental theoretical results demonstrate that multiple intermolecular interactions centers different aggregates are responsible for generation multicolor emission. The anticounterfeiting explored. Besides, compound exhibits high antibacterial activity benefiting efficient 1O2 generation. This work provides an way prepare color-tunable
