We report a light‐irradiation method to control the synchronous nucleation of a donor‐acceptor (D‐A) fluorophore for growing highly uniform single‐crystalline microrods, which is in sharp contrast to the prevailing methods of inhibiting spontaneous nucleation and additionally adding seeds. The D‐A fluorophore was observed to undergo photoinduced electron transfer to CrCl3, leading to the generation of HCl and the subsequent protonation of the D‐A fluorophore. By intensifying photoirradiation or prolonging its duration, the concentration of protonated D‐A fluorophores can be rapidly increased to a high supersaturation level. This results in the formation of a controlled number of nuclei in a synchronous manner, which in turn kickstart the epitaxial growth of protonated D‐A fluorophores towards uniform single‐crystalline microrods of controlled sizes. The light‐regulated synchronous nucleation and uniform growth of microrods are a unique phenomenon that can only be achieved by specific Lewis acids, making it a novel probing method for sensitively detecting strong Lewis acids such as chromium chloride.

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.

“…[2b-c] Although this coassembly approach represents a leap in constructing small molecule-based 2D structures via living self-assembly, the coformer (alcohols) incorporated is disadvantageous to certain optoelectronic properties such as photostability. [6] Therefore, developing new living self-assembly methodology to construct uniform and size-controlled 2D structures from single functional small molecules is highly desired but remains a great challenge.…”

This study reports the design of a donor‐acceptor (D‐A) molecule with two fluorene units on each side of a benzothiadiazole moiety, which allows multiple intermolecular interactions to compete with one another so as to induce the evolution of the metastable 2D platelets to the stable 2D platelets during the self‐assembly of the D‐A molecule. Importantly, the living seeded self‐assembly of metastable and stable 2D structures with precisely controlled sizes can be conveniently achieved using an appropriate supersaturated level of a solution of the D‐A molecule as the seeded growth medium that can temporarily hold the almost‐proceeding spontaneous nucleation from competing with the seeded growth. The stable 2D platelets with smaller area sizes exhibit higher sensitivity to gaseous dimethyl sulfide, illustrating that the novel living self‐assembly method provides more available functional structures with controlled sizes for practical applications. The key finding of this study is that the new living methodology is separated into two independent processes: the elaborate molecular design for various crystalline structures as seeds and the application of a supersaturated solution with appropriate levels as the growth medium to grow the uniform structures with controlled sizes; this would make convenient and possible the living seeded self‐assembly of rich 1D, 2D, and 3D architectures.
