| The ability to detect the presence of certain chemical compounds at low concentrations is important on many levels including, but not limited to, healthcare, industrial process control, environmental testing, and military operations. Fluorescence-based chemical sensing is an important and promising means of doing this because it offers a quantitative, visual response with exceptional sensitivity for various analytes. There are several known fluorescence sensors shown to work well in solution phase. However, solid-state analogues are often more desirable due to the fact that they minimize sample contamination, and perhaps more importantly, they can be recovered and used again after regeneration of the sensing element. Solid-state fluorescent chemical sensors based on nanoporous inorganic supports such as zeolites and mesoporous sieves have recently been of interest because these systems have shown enhanced sensing performance due to their nanostructures. Herein, the development of unprecedented lyotropic liquid crystal (LLC) monomers containing fluorescent headgroups and ordered nanoporous LLC polymers with chemosensing capabilities are discussed. |
