摘要
以2-(4-(3,6-叔丁基-9咔唑基)苯基)-1氢-嘧唑[4,5-f][1,10]邻菲罗啉(L)为配体合成了一种Re(I)配合物——ReL(CO)_3Br,并应用静电纺丝法将其掺杂到聚苯乙烯(PS)纤维中。在充分分析ReL(CO)_3Br的光物理性质的基础上,对ReL(CO)_3Br/PS纤维的光学氧传感性进行了分析。发现ReL(CO)_3Br位于553nm处的磷光峰对氧气比较敏感,实验研究表明ReL(CO)_3Br/PS纤维的磷光发射可以在10秒钟内对氮氧混合气中氧气浓度的变化产生响应。与在纯氮气中相比,在纯氧中ReL(CO)_3Br/PS纤维的发光强度发生50%淬灭。
A Re（I） complexe of ReL（CO）_3Br,where L is 2-（4-（3,6-tert-butyl-9carbazoly）phenyl）- 1H-imidazo[4,5-f][1,10]phenanthroline,was synthesized and used to prepare ReL（CO）_3Br containing polystyrenefibres by the electrospinning. The photophysical properties and the singlet oxygen sensoring properties of ReL（CO）_3Br,as well as the opticalsinglet oxygen（O_2） sensor properties of ReL（CO）_3Br/PS were fully characterized. It was found that the emission band at 553 nm of ReL（CO）_3Br is sensitive to O_2 and the phosphorescent emission of ReL（CO）_3Br/PS fibres,which could be50% quenched by pure O_2 compared to that in N_2,could respond in 7 s to the changement of N_2 and O_2 atmosphere.
