AB  - The synthesis of mesostructured silica from a tetrahydrofuran (THF)-based sol gel 
      was carried out in the channels of an anodic alumina membrane (AAM) using the 
      evaporation-induced self-assembly (EISA) method. Two different nonionic 
      surfactants were used as structure-directing agents, the triblock copolymer 
      Pluronic P123 and the oligomer surfactant Brij56. The effect of the relative 
      humidity and surfactant concentration on the type of mesophase and orientation of 
      the in-channel mesostructures was studied using transmission electron microscopy 
      (TEM) and grazing incidence small angel X-ray scattering (GISAXS). The in-channel 
      structures obtained in this study were primarily of the 2D hexagonal phase with a 
      circular orientation in which the hexagonally packed cylinders form a spiral-like 
      shape from the channel wall inward. In addition, a columnar orientation of the 
      hexagonal phase, in which the axes of the hexagonally packed cylinders are 
      oriented parallel to the channel axes, was also observed. Finally, the use of the 
      THF-based synthesis allowed the in situ incorporation of the highly hydrophobic 
      yellow-emitting conjugated polymer poly[9,9-dioctylfluorene-co-benzothiadiazole] 
      into the in-channel mesostructure upon its formation. The conjugated polymer was 
      well distributed within the mesostructure and maintained its optical properties.
