Organic solid-state lasers composed of π-conjugated compounds are expected to be high-brightness light sources with solvent processability and easy wavelength tunability through chemical structure designing. Organic solid-state lasers are preferably made of materials that have both high solvent processability and high luminescence, but there is no design method that can simultaneously satisfy both of the properties. In this work, we discovered that it is possible to improve the solubility and luminescence of molecules that become organic single crystal lasers not only by conventional molecular design but also from the standpoint of crystal engineering, which suppresses intermolecular CH-π interactions.
