(Figure Presented) Gelling together: Merocyanine dyes possessing a cholesterol group as a gelforming auxiliary self-assemble into nanoscopic fibers in apolar cyclohexane and polar acetone to form organogels, showing dramatically distinct optical properties through exciton coupling. This dramatic change is a result of different chromophore packing arrangements within the nanoscopic fibers (see fluorescence microscopy images with photographs of the gels as insets). 2007 Wiley-VCH Verlag GmbH & Co.
