N2 - Hybrid organic-inorganic nanocomposites have attracted considerable attention for developing advanced multifunctional materials in optics, electronics, energy, membranes, catalysts, and sensors [1]. In particular, confinement of one-dimensional (1D) molecular assembly in the channels of thermally stable inorganic mesoporous silica can enhance physical and chemical properties of organic motifs due to site-isolation or long-range molecular ordering [2]. For immobilization, amphiphilic organic motifs as a template have been utilized in the sol-gel synthesis because this method guarantee dense filling of functional groups in the silicate nanochannels [3, 4]. The resulting mesoporous nanocomposites are promising materials in optoelectronic applications for high temperature operation and stability of future light sources and displays using in phosphorescent organic light emitting devices (PHOLEDs) with a longer lifetime and higher luminescence quantum yield [5]. However, no example of 1D molecular assembly in the silicate nanochannels has yet been reported so far for addressing this challenging issue.
