Low in, high out : Single crystals of a thiomethyl‐terminated oligo(phenylene vinylene) exhibit unique photonic properties including strong anisotropic solid‐state fluorescence (see depicted optical and fluorescence micrographs; arrows: polarization direction), high quantum yield, large two‐photon absorption cross section, and stimulated emission, which make it a candidate for opto‐electronic applications such as upconversion lasing.
