Designing Nonconventional Luminescent Materials with Efficient Emission in Dilute Solutions via Modulation of Dynamic Hydrogen Bonds

“…Fe 3+ is one of the essential trace elements for human growth and development. At the same time, it is closely related to a range of diseases, such as diabetes, liver and kidney damage, and anemia [ 40 , 41 , 42 , 43 , 44 ]. In other words, the detection of Fe 3+ is important for the early identification and diagnosis of diseases caused by abnormal Fe 3+ concentrations in the human body.…”

Room temperature tunable multicolor phosphorescent polymers for humidity detection and information encryption

“…The past decade has witnessed the extensive investigation of polymer-based RTP materials owing to low cost, easy processing and low toxicity compared with crystalline RTP materials and coordination complexes containing noble metals. [15][16][17][18][19][20][21][22] For example, Kim and co-workers devised Diels-Alder click chemistry as a method to covalent cross-linking between phosphors and polymer matrices to suppress molecular motions for enhanced RTP of metal-free organic materials. 23 Tian and co-workers developed a facile way to construct pure organic amorphous polymers with high phosphorescent quantum yields and ultralong RTP lifetimes by the simple radical binary copolymerization of acrylamide and different phosphors without extra processing.…”

Room-temperature phosphorescent polymers with excitation-wavelength and delay-time emission dependencies

“…[32][33][34] In our previous work, we demonstrated that ionic bonds restricted the molecular motions (rotations and vibrations), thus fabricating polymer materials that contained unconventional chromophores displaying persistent phosphorescent emission behavior at room temperature. 35,36 The presence of ionic bonds, which have shorter bond length and higher bond energy than hydrogen bonds, halogen bonds, and other intermolecular forces, renders them more effective in reducing the molecular motions that, thus, negatively impact the non-irradiation and improve emission efficient. Indeed, the polydispersity of the molecular weight is one of the remarkable characteristics of polymers, which may form multiple emitting centres [37][38][39] and emit multicolor RTP under different excitation wavelengths.…”
