具有荧光性能氧化石墨烯杂化材料的制备及性能研究

Functionalized graphene oxide (GO) materials possess enormous potential applications, and become an active research field in material science. However, fluorescently functionalizing GO is still a difficult task, since GO itself possesses fluorescence quenching ability. In this study, we prepared a kind of functionalized GO hybrid material with fluorescence property, through a "click reaction" between alkynylated small fluorescent organic molecules and GO sheets grafted with azido groups. The resulting fluorescent GO hybrid material was subjected to characterizations including FT-IR, Raman, XRD, HRTEM, fluorescence microscopy, etc. The characterizations in combination identified the success in preparing the target fluorescent hybrid material. Furthermore, we tentatively put forward a possible mechanism for the fluorescence emission of the material.
