Preparation of Rubrene Nanomaterials and Their Sensing Effect on n-butylamine
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.
