Abstract

A highly fluorescent (ΦF =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 >500 nm in diameter, 1.7 nm in thickness, and 3.9 nm in the honeycomb pore diameter. This 2D SOF holds potential as a new all-organic photosensitizer template for photocatalytic H2 evolution from pure water.
