A New Phase of Oriented Mesoporous Silicate Thin Films. -Silicate/surfactant thin films of P63/mmc structure are grown either on mica or at air-water interface using a double-headed quaternary amine surfactant. Characterization by XRD and TEM shows that these films, which are stable to calcination,

q m = 0.0224 ±1 , which gives the domain [9] center-to-center spacing of 280 (D = 2p/q m ). A number of additional broad scattering maxima were also observed at higher q, but the positions are somewhat unclear for this sample due to the noise in the data. Figure shows a SAXS profile of porous MSSQ
