聚合型荧光增白剂

聚合型荧光增白剂是由荧光单体与其他单体聚合而成，可解决传统荧光增白剂耐光性差等缺点.简要介绍了聚合型荧光增白剂的分类，讨论了二苯乙烯、萘酰亚胺、芘类聚合型荧光增白剂的合成、结构、性能及应用.聚合型荧光增白剂中基本发色团的结构不变，具有传统荧光增白剂的光学性能；发色团与高分子链间的共价键使其光化学稳定性大大增强，增白性能和荧光量子产率显著提高.聚合型荧光增白剂可应用于纺织品、聚合物材料和洗涤剂，还可用于液晶显示器、荧光探针等高科技领域.开发环保型高性能新产品、不同类型增白剂共混与复配以及多个含不同发色团单体间的聚合有可能成为新的研究热点.

Polymeric fluorescent brighteners

Polymeric fluorescent brighteners (PFBs) which are polymerized by fluorescent monomer and other monomers can solve poor photostability of traditional FBs.Classification of the PFBs is briefly introduced.The synthesis, structure, properties and application of stilbene, naphthalimide and pyrene FBs are discussed. The basic structure of chromogen in PFBs remains the same,so PFBs have fluorescent properties of traditional FBs.Covalent bonds between chromogen and macromolecule chains enhance their photochemical stability,increase their whitening performance and fluorescence quantum yield. PFBs can be used not only for textile, polymeric materials and detergents,but also for high technology fields,such as liquid crystal displays,fluorescent probes, etc.Developing environmentally friendly high performance new products, mixing different PFBs and polymerizing more monomers with different chromogens are likely to be new areas of research.
