Based on a supramolecular assembly strategy, Yan and co-workers obtain two-component molecular solid-state materials of diphenyloxazole (DPO) through a solution-growth process. On page 587, the DPO-based high-quality single crystals display tunable luminescence properties (such as emissive wavelength, color, and fluorescence lifetime) as well as multicolor polarized emission in the UV/blue/green region. This is similar to, in a macroscopic scenario, the variable light emitted from Canton tower (the highest tower in China, shown here) at the side of the Zhujiang river.
