“…Similar to the stacking in the cocrystal of 24FQL/TFPTA , each 24FQL column was separated by four TFBA molecules in the B plane, where 24FQL behaved as a disorder of location (Figure S1b). , Besides, two neighboring 24FQL molecules in the B plane stacked in an antiparallel form with a d value of 3.51 Å and a θ 2 of 100.72° (Figure S1d, Chart S1, Table S3), which meet Schmidt’s criteria, so [2 + 2] cycloaddition might take place.…”

In previous reports, the solid-state photo-induced [2 + 2] cycloaddition of styrylpyridine or styrylquinoline derivatives took place only assisted by templates. Herein, (E)-2-(2,4-difluorostyryl)quinoline (24FQL) and (E)-2-(3,5-difluorostyryl)quinoline (35FQL) have been synthesized and can undergo photodimerization in the pristine crystals. Interestingly, the photomechanical effects of the plate-like crystals are triggered by the photochemical reaction. Furthermore, the cocrystal approach was employed to harmonize the photochemical reactivity of 24FQL and 35FQL as well as the photoactuation performance of the molecular crystals. In the cocrystals of 24FQL/TFBA and 24FQL/TFPTA, the [2 + 2] cycloaddition reactivity of 24FQL decreased compared with that in a one-component crystal. However, the cocrystals showed more significant photoactuation. It was deduced that during the [2 + 2] cycloaddition, more intermolecular interactions would be broken in cocrystals, which might weaken the reactivity but enhance the photomechanical performance due to more strain being accumulated. On the contrary, the photochemical conversion of 35FQL was improved significantly in cocrystals of 35FQL/TFBA and 35FQL/TFPTA, leading to obvious photo-induced movement. Therefore, the cocrystal strategy can be a useful tool to harmonize the photochemical reactivity and photomechanical behaviors of the potentially photoactive molecular crystals.

Comprehensive SummaryThe Haber‐Bosch process, which is used for ammonia (NH3) synthesis, requires vast amounts of energy, accounting for approximately 1%—2% of the world's annual energy consumption. Therefore, researchers in both industry and academia are interested in developing sustainable and environmentally friendly methods for synthesizing nitrogenous compounds at ambient conditions using renewable energy sources such as visible light. While several examples of thermal activation of dinitrogen molecules have been demonstrated using various transition metals and ligand frameworks, the use of light to weaken or split the strong N—N bond has been less explored. This article presents an overview of molecular complexes capable of dinitrogen photocleavage and provides mechanistic insights into the photoactivation process through experimental and theoretical studies. We believe this review will provide readers with an in‐depth understanding of the current state‐of‐the‐art and future research perspectives, particularly in the use of visible light for dinitrogen activation and transformation.
