We use a cocrystal with components arranged in a 1D hydrogen-bonded chain as a pseudoseed to template the components of a cocrystal that otherwise forms a photoactive 0D assembly to form a photostable 1D chain structure.rnCocrystal formation is a highly-effective means to construct organic solid-state materials that exhibit tailorable properties (e.g. optical, photo, electrical, mechanical, pharmaceutical). The success of cocrystallization in the synthesis of functional materials is based on the modularity of cocrystal design; specifically, the ability to exchange components with an intention to fine-tune a property of a solid. A major area of focus in the design of cocrystals is control of topology. One-dimensional- (1D), 2D-, and 3D-architectures, as well as 0D assemblies, with components that form functional porous and condensed frameworks have been reported. Indeed, the field of network and assembly design via cocrystals, and related metal-organic frameworks, is now at a stage where steric and electronic properties of the components can be fine tuned to impart systematic changes to the topology.
