| 1 | Recent progress in organic color-tunable phosphorescent materials显示文摘Organic color-tunable phosphorescent materials depend upon multiple emission centers to achieve colortunable phosphorescence with changes in excitation wavelength,temperature,time,and other external factors.Organic color-tunable phosphorescent materials are becoming increasingly popular due to their potential applications in anticounterfeiting,encryption and sensing.This brief review focuses on the formation of multiple emission centers in organic color-tunable phosphorescent materials and how to ensure that these multiple emission centers can simultaneously emit.In the future,materials with a large color tunable ranges,increased efficiency,and relatively long lives will be developed. | Zhengshuo Wang Hua Yuan Yongzhi Zhang Dandan Wang Junping Ju Yeqiang Tan | 2022 | Journal of Materials Science & Technology2022，，6： | 1 |
| 2 | Research progress on the luminescence of biomacromolecules显示文摘Luminescent materials show great potential in various applications.Traditional aggregation-induced emission(AIE)luminogens are mostly produced by complex organic synthesis and have poor hydrophilicity and biocompatibility,which limit their practical applications.Therefore,it is of great significance to develop fluorescent materials with good hydrophilicity and biocompatibility,and biomacromolecules with these properties have attracted our attention.Partial biomacromolecules can generate unique new fluorophores during the gelation process to obtain hydrogels with good fluorescence properties.In addition,biomacromolecules can be modified with fluorescent groups to obtain fluorescent materials with excellent performance,thus improving the hydrophilicity and biocompatibility of fluorophore.In particular,grafting aggregation-caused quenching(ACQ)luminogens onto biomacromolecules can even effectively inhibit the aggregation and self-quenching of luminogens.It is well known that aromatic biological macromolecules such as green fluorescent protein have intrinsic fluorescence.Intrinsic fluorescence is also observed in nonaromatic biological macromolecules without traditional chromophores such as chitosan,cellulose and sodium alginate.The luminescence of nonaromatic biomacromolecule can be rationalized by the clustering-triggered emission(CTE)mechanism,namely,clustering of nonconventional chromophores and subsequent electron overlap and conformation rigidification are accountable for the emssion.In this review,fluorescence gels obtained from biomacromolecules,biomacromolecules modified with fluorophores,and the intrinsic luminescence of biomacromolecular luminogens are assessed.This review will help to develop low-cost,biocompatible luminescent materials and has great significance for comprehending the luminescence of nonconventional luminophores and expanding the application of luminescent compounds. | Dandan Wang Junping Ju Shuang Wang Yeqiang Tan | 2021 | Journal of Materials Science & Technology2021，，17： | 0 |
| 3 | Seaweed polysaccharide fibers:Solution properties,processing and applications显示文摘Seaweed polysaccharides with abundantly renewable sources and charming properties have attracted arising attention.Alginate,carrageenan and agar with the largest are the most predominant species of common seaweed polysaccharides.This review will first provide a comprehensive overview of general information on seaweed polysaccharides regarding solubility,multilevel structure,viscoelasticity,and gelation.Then we summarize preparation methods of seaweed polysaccharides fibers including wet-spinning technique,electrospinning technique and microfluidic spinning.The applications of seaweed polysaccha-rides fibers,based on many excellent inherent properties,including biocompatibility,suitable microstruc-ture,nontoxicity,potential bioactivity,good intrinsic flame retardancy and thermal stability,are described in detail. | Junping Ju Jinzhu Yang Wenchao Zhang Yuting Wei Hua Yuan Yeqiang Tan | 2023 | Journal of Materials Science & Technology2023，，9： | 0 |
