Cocrystal engineering is gaining interest across various disciplines since it can effectively tune the properties of solid substances via noncovalent synthesis by introducing new components into the lattice. Mechanochemistry is without a doubt the most valuable tool for the research of cocrystals, which combines the pursuit of efficient and sustainable process pathways with the exploration of supramolecular synthons that cannot be discovered using solution methods. In this review, concerning the significance of the mechanochemical synthesis of cocrystals, we begin by outlining the strategies for mechanochemical preparation of cocrystals. We then elaborate on the theoretical mechanisms of the mechanochemically induced formation of cocrystals and their polymorphs. On this foundation, several cross-fields in which mechanochemistry enhances the application value of cocrystal engineering are shown to overcome existing limitations, which are difficult or impossible to access using conventional solution methods. More importantly, we demonstrate that the introduction of new methods, such as cultivating single crystals from melt microdroplets, and new techniques, such as microelectron diffraction (Micro-ED), has harmoniously united the fields of cocrystal engineering and mechanochemistry. Finally, a brief conclusion and outlook are presented, including current challenges and future opportunities for the cooperation of mechanochemistry and cocrystal engineering.

Due to the poor efficacy and environmental contamination caused by ease leaching, highly water-soluble herbicides have raised considerable attention. For example, metamitron (MET), a herbicide which used for controlling grass...

Achieving rapid global agricultural development while maintaining ecological harmony is a major challenge of the new millennium. Meeting this challenge requires the development of efficient and environmentally friendly agrochemicals, including pesticides and fertilizers. Molecular assembly, as a promising strategy, has garnered significant attention in recent years for the development of advanced solid-state forms of agrochemicals. In this review, we present the potential and recent advancements of solid-state forms, such as polymorphs, cocrystals/salts, solvates, inclusion compounds, and the amorphous state, for the production of high-efficiency and low-polluting agrochemical products. We provide an overview of the concepts and preparation methods of these solid-state forms, followed by an exploration of their applications in sustainable agriculture. Specifically, we highlight their value in enhancing pesticide solubility, enabling controlled release of chemical fertilizers, and reducing off-target risks. Lastly, we discuss the challenges and prospects associated with the utilization of solid-state forms for the advancement of environmentally friendly and efficient agriculture.
