摘要
合成了一种新的以柔性羧酸为配体的铜配位聚合物,考察了其热稳定性能、荧光性能及储氢能力.结果表明,配体2-硝基-苯-1,4-二(氧乙酸)表现出较好的柔韧性;该结构在温度低于541 K的环境中比较稳定,当温度高于541 K迅速发生分解并伴随着轻微的爆轰.配合物的荧光光谱与配体的相比有所蓝移.与此同时,该配合物的储氢能力随着氢气压力的增加而提高;当氢气压力为5.0 MPa时储氢能力可达0.42%.
A novel copper coordination polymer was constructed based on flexible carboxylate ligand.The thermal stability,photoluminescence property,and hydrogen storage capacity of the complex were investigated.It has been found that ligand 2-nitro-benzene-1,4-di（oxyacetic） acid has good flexibility.Its framework is stable up to 541 K,and above 541 K it decomposes rapidly with a weak detonation.Besides,the photoluminescence spectrum of the complex is slightly blue-shifted as compared to that of the ligand;and its hydrogen storage capacity increases with increasing hydrogen pressure.A hydrogen storage capacity of 0.42% was obtained at a hydrogen pressure of 5.0 MPa.
