基于联苯-碳硼烷磷光材料的制备及光学性能
Design,Synthesis and Photophysical Properties of Bibenzene-carborane Phosphorescent Material
摘要
Abstract
The phosphorescent compound o-1 was designed and synthesized by coupling biphenyl and carborane through the reaction of Sonogashira and hybrid Diels-Alder.The molecular structure of o-1 was confirmed by 1H-NMR,13C-NMR and 11B-NMR.The o-1 crystallographic data were obtained by single crystal X-ray diffractometer(XC-XRD).Crystallinity was confirmed by small angle X-ray diffractometer(PXRD).The thermodynamic properties of o-1 were obtained by thermogravimetric analysis(TGA)and differential scanning calorimetry(DSC).The optical properties of o-1 were characterized by constant temperature transient fluorescence and phosphorescence.The results show that the phosphorescence and fluorescence of o-1 are obviously responsive to temperature.With the decrease of temperature,the phosphorescence intensity and lifetime of o-1 increase significantly,and the phosphorescence lifetime of 77 K reaches 120 ms.The color changes from green to blue as the temperature decreases.关键词
