Abstract
Environmentally friendly hydrophilic polymer materials are easily affected by air humidity at room temperature, which weakens their quantum yield and lifetime. Based on the advantages of polymer hydrogen bonds and host–guest limits in the preparation of phosphorescent materials, we prepared a series of flexible dual-network films with high tensile strength and moisture resistance by using the properties of cucurbit[8]uril that can encapsulate bimolecularly at the same time, achieving color-tunable RTP from green to warm white after turning off the UV. These flexible and processable films had broad application prospects for multicolor afterglow displays, UV detection, and multilevel information encryption activities. In the meantime, due to their excellent moisture resistance and tensile properties, the service lifetimes of the phosphorescent films were greatly extended.
期刊介绍：
Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
