The compound 2-naphthol and surfactant AOT have been found to form gels in nonpolar solvents via self-assembly. The gel can be applied to an emitting organogel upon UV excitation. NAIR spectroscopy revealed that 2-naphthol has a stacked structure in which naphthyl pi-pi overlap is maximized, and the exterior of this structure is surrounded by AOT. This organogel emits blue light under UV excitation because of dense stacking of the 2-naphthol framework. When a Eu3+ complex exhibiting orange emission was dispersed in the gel, pinkish-white emission was observed because of an additive color-tuning of the gel body and the Eu3+ complex dispersed in it.
