A highly fluorescent (phi(F)=0.60) and water-soluble two-dimensional (2D) honeycomb-shaped supramolecular organic framework (SOF) was successfully synthesized in pure aqueous solution via self-assembly of novel cyanostilbene-functionalized trilateral guest molecules and cucurbit[8]uril hosts. The size of this fluorescent 2D SOF was >500nm in diameter, 1.7nm in thickness, and 3.9nm in the honeycomb pore diameter. This 2D SOF holds potential as a new all-organic photosensitizer template for photocatalytic H-2 evolution from pure water.
