摘要：

First application of CARS spectroscopy for visualization of probe liquid crystal (LC) molecules nanoconfined to mesoporous silica host is reported. Mesoporous molecular sieves (Al-MCM-41, KIT-6, and SBA-15) loaded with nematic 5CB as probe molecules were studied using a home-built CARS microscope. The images were registered in a forward mode in 1260-1700 cm(-1)spectral range. It was found that Al-MCM-41 showed the maximum density of the adsorbed species and the best filling uniformity among the studied hosts. The observed differences are explained by different active sites distribution and LC interaction with the host pore surface.
