A solid-solution approach for controllable photomechanical crystalline materials.

ABSTRACT: Solid solutions are a unique and elegant crystal engineering strategy to control the properties of crystalline materials, and the tunability of physicochemical properties it provides has a wide scope of applications. In this research, we bring this strategy to the realm of smart molecular crystals and explore solid solutions of organic photomechanical crystals to create flexible structures that exhibit a gradient of predetermined emissive, mechanical, and reactive properties. Specifically, we demonstrate that fluorescence, mechanical properties, and solid-state photoreactivity in a binary mixed crystal system of 9-anthraldehyde (9AA) and 9-methylanthracene (9MA) can be simultaneously and precisely tuned simply by changing the composition. The statistical distribution of the two components
