A novel cruciform oligo(phenylene vinylene) chromophore has been designed and emits green–blue light with high photoluminescence (PL) efficiency both in solution and in the solid state, as shown in the figure. The cruciform shape impedes crystallization and allows amorphous films of the molecule to be produced by spin-coating. The high PL efficiency, strong two-photon-excited fluorescence, and good film-forming abilities make this molecule a promising candidate for use in solid-state optical devices.
