Amphiphilic bidentate structure directing agents (SDAs) were prepared through condensation between salicyldehyde and long chain primary amines followed by reduction of the imines with NaBH4. These SDAs were used to synthesize novel mesoporous titanium based composite materials under mild hydrothermal conditions. Powder XRD, TEM-EDS, FE-SEM, CHN chemical analysis, N2-sorption, 1H and 13C NMR, HR MS, FT-IR, UV–visible absorption and emission spectroscopic tools were employed to characterize the SDAs and the novel materials. XRD and TEM image analysis suggested the mesophase with wormhole-like disordered structure in these samples. These mesostructured titanium-composites showed good photoluminescence properties at room temperature, which could be utilized for the fabrication of novel optoelectronic materials.
