摘　　要：以红荧烯(Rubrene,简称RBE)为原料,采用真空气相沉积—分子自组装法制备了RBE有机纳米材料。通过电镜(SEM)、荧光光谱、紫外光谱及傅立叶变换红外光谱对纳米材料RBE进行表征。利用超声-乙醇溶解得到纳米溶液,用荧光测定有机小分子乙酸、甲苯、甲醇、正丁胺、三乙胺、硝基苯、甲酰胺、苯、乙醇、乙酸乙酯、丙酮、乙醇胺、乙腈、四氢呋喃对RBE纳米材料的猝灭作用,发现正丁胺对该纳米结构具有较强的猝灭作用,以此建立了测定正丁胺蒸汽分子的RBE荧光传感新方法。Rubrene(RBE)was used as the raw material to prepare RBE organic nanomaterials using vacuum vapor deposition and molecular self-assembly method.Characterizied of RBE nanomaterials by using electron microscopy(SEM),fluorescence spectroscopy,ultraviolet spectroscopy,and fourier transform infrared spectroscopy.A nano solution was obtained by ultrasound ethanol dissolution,the fluorescence quenching effect on RBE nanomaterials were determined by organic small molecules,i.e.,acetic acid,toluene,methanol,n-butylamine,triethylamine,nitrobenzene,formamide,benzene,ethanol,ethyl acetate,acetone,ethanolamine,acetonitrile,and tetrahydrofuran.It was found that n-butylamine has a strong quenching effect on the RBE nanostructure,and a new RBE fluorescence sensing method was established for measuring n-butylamine vapor molecule.
