Zeolites and related substances, such as aluminophosphates with periodic three-dimensional framework structures which contain pores, have attracted much scientific interest for applications in chemical separation, shape-selective catalysis, host/guest chemistry, and low dielectric constant (low-κ) materials preparation, etc. The recent interest in organically functionalized mesoporous and microporous inorganic materials arises from the advantages that the disparate moieties bring to the system. Although the synthesis of organically functionalized periodic mesoporous organosilicas has been extensively reported, there has been limited success in the functionalization of microporous materials. Herein, we describe the preparation of phenyl-functionalized AlPO4-H1 (VPI-5). The functionalization of AlPO4-H1 with phenylphosphonic acid was investigated by solid state 13C and 31P NMR, BET, XRD, FTIR, EDX, and TGA.
