| Gels derived from low-molecular-mass organic gelators (LMOGs) with π-conjugated molecular structure have attracted considerable interest in recent years due to their special properties of organogel networks for thier potential applications in optoelectronic fields, including enhanced charge transport, fluorescence and sensing abilities. Especially, a smart gel can be rendered sensitive to external stimuli such as light or chemicals, which makes it possible to utilize the gel as potential candidate for delivery system, device, sensors, chemical valve and switches. In this work, we have designed and synthesized a photo-responsive fluorescent organogel system, which demonstrates pattern-wised UV-triggered gel-to-sol transition. It was found that the fluorescent intensity in the gel state with remarkable fluorescence change is enhanced over several hundreds times compared to that in the solution state. This is clearly due to the principle of the aggregation-induced enhanced emission demonstrated early by us (JACS, 2002, 124, 14410). |
