However, conventional solution-based crystallization methods often result in polymorphic mixtures and lack precise control over product composition. Herein, we report a comparative investigation of solution crystallization <em>versus</em> mechanochemical synthesis for constructing MOSs from 9-anthracenecarboxylic acid (ACA) and 4,4′-bipyridine (BPY). Solution-based approaches consistently yielded concomitant formation of neutral cocrystal (CC) and ionic cocrystal (ICC) forms, regardless of the solvent used. The resulting multicomponent solids were comprehensively characterized using a combination of single crystal X-ray diffraction, powder X-ray diffraction, Fourier-transform infrared spectroscopy, differential thermal analysis, and thermogravimetric analysis. In contrast, mechanochemical methods, including neat grinding (without solvent) and liquid-assisted grinding (with minimum solvent), enabled selective formation of either a phase pure CC or ICC form. Less polar and nonpolar organic solvents favor the kinetic CC, while polar water promotes formation of the thermodynamically stable ICC. Time-resolved <em>in situ</em> powder X-ray diffraction (TRIS-PXRD) captures the dynamic evolution of solid-state phases and reveals the complete transformation of the CC into ICC under neat grinding or water-assisted conditions.

The transition from form 1 to form 4 at 268 K exemplifies a first-order solid-state phase transition, marked by a significant enthalpy difference between the polymorphs, suggesting a relatively low kinetic barrier for this transition.

However, the process of growing SiC is intricate, involving multiple physical and chemical interactions such as heat and mass transfer. The closed-system nature of crystal growth presents challenges in monitoring the thermal and flow fields. To elucidate the molten flow dynamics during SiC crystallization and optimize growth rate uniformity <em>via</em> thermal system engineering, this study first validated the numerical simulation methodology through small-scale crystal growth experiments. Subsequently, an orthogonal experimental design was implemented to systematically investigate the effects of the heating configuration, crystal rotation rate, and crucible rotation direction on temperature uniformity, flow field characteristics, crystal growth kinetics, and carbon distribution homogeneity in a large-scale SiC growth system. The results indicate that the centrifugal force generated by the rotation of the crystal and crucible during the growth process has the most significant effect on the flow, followed by the Lorentz force from electromagnetic induction heating, while the buoyancy force caused by temperature gradients has the least effect. The order of factors affecting the average crystal growth rate during the SiC growth process is the heating mode, crystal rotation speed, and crucible rotation speed. However, the effects of these factors on the uniformity of grown crystals exhibit an inverse trend. This study suggests that the most effective combination of factors for achieving the desired outcome would be simultaneous electromagnetic induction and resistive heating, a rotation speed of 30 rpm for the crystal and a rotation speed of −10 rpm for the crucible.
