氧化偶联共聚合制备主链含β-萘烷基醚的红色发光聚合物

用氧化偶联聚合法合成了主链上含β-萘烷基醚和吡啶、二烷基芴、二苯乙烯和均四甲苯的聚合物.用FT-IR和1H NMR表征了聚合物的结构.广角X射线衍射表明共聚物的结构都是非晶态的.用UV-V is表征了共聚物的吸收特征.聚合物的荧光光谱表明,含有β-萘烷基醚和吡啶的聚合物在溶液中表现为红光发射材料.含有β-萘甲醚和二苯乙烯的共聚物为黄橙光发射,通过改变单体含量也可实现红光发射.含有β-萘甲醚和二烷基芴的聚合物固体有望成为白光发射材料.

Red Light-Emitting Polymers Containing β-Alkyloxynaphthalene in the Main-chain Prepared by Oxidative-coupling Copolymerization

The copolymers incorporated β-alkyloxynaphthalene with pyridine,stilbene,9,9-di(2-ethylhexyl)fluorene and 1,2,4,5-tetramethylbenzene were prepared by oxidative coupling copolymerization.The structure of polymers was characterized by ~(1)H NMR and FT-IR.The copolymers are all amorphous.The light absorbance of the polymers were characterized by UV-Vis spectroscopy.The fluorescence spectra of polymers in chloroform solution display that the copolymers of β-alkyloxynaphthalene and pyridine are red light emitting materials.The copolymer of β-methyloxynaphthalene and stilbene displays orange light emission,and can display red light emission by changing the moieties contents.The fluorescence spectrum of the copolymer of β-methyloxynaphthalene and 9,9-di(2-ethylhexyl)fluorene in solid film displays a hopeful white light emission.
