Preparation of porous boehmite nanosolid and its composite fluorescent materials by a novel hydrothermal hot-press method

Boehmite (AlO(OH)) porous nanosolid has been successfully prepared by a novel hydrothermal hot-press (HHP) method, using Al2O3 nanoparticles as the starting material. Furthermore, a new organic fluorescent material (E,E)-4-{2-[P′-(N,N-di-n-butylamino)stilben-p-yl]vinyl}pyridine (DBASVP) was assembled into the pores of the boehmite porous nanosolid, thus a DBASVP/boehmite porous nanocomposite was obtained. Because of the interaction between DBASVP molecules and the surface of boehmite porous nanosolid, a red-shift of the fluorescent peak was observed in boehmite/DBASVP composite by comparing with that of DBASVP.
