Organic semiconductor crystals with long-range order and designable properties are pivotal in optoelectronic devices. Organic crystals bonded by weak intermolecular interactions usually follow non-classical crystallization trajectories, yielding polymorphs with distinctive properties but extremely difficult to control. We present a method for deterministic control of polymorphs, yielding organic microcrystal arrays with distinctive crystal structures and emission spectra. To elucidate the mechanisms of molecular self-assembly, we track the real-time dynamics of molecular nucleation, Ostwald’s ripening, and polymorph formation. Based on this method, we extended our regulation strategy to multiple molecules, achieving programmable polymorphic formation with broadly tunable emission spectra (450–705 nm) and anisotropic polarized emission. On a single substrate, we integrated multidimensional polymorphic information including position, wavelength, intensity, and polarization, constructing a high-density optical information storage platform with an information density of 215 bits/cm2, thereby opening potential technological pathways for future optical information storage technologies.
Understanding the relationship between material properties and supramolecular nanostructures is essential for elucidating how nanoscale molecular organizations govern macroscale photoluminescence (PL) properties. Here, we introduce a novel pyrene-based liquid crystal mesogen (Py-LCM) and systematically investigate how...

Three-dimensional protein crystals are ordered, porous macroscopic materials with potential applications in catalysis, biosensing, and biomedicine. However, most protein crystals are obtained by empirical screening, providing limited control over the lattice architecture, pore geometry or component composition that det...

Soft porous crystals exploit adaptive structural dynamics for molecular recognition, yet their elusive nature hinders the fundamental understanding of rational design and reliable applications. Here, the correlation dynamics intrinsic to layered M(pbe)-α (M = Co2+, Zn2+, Cu2+), transmitting from mono-vertex to strained...

Crystalline self-assembly offers a powerful route to ordered organic materials with well-defined structures and morphologies. Despite substantial advances in controlling crystal habit, organic single crystals with precisely engineered architectures, particularly those with fully enclosed internal cavities, remain exc...

Crystallization-driven self-assembly (CDSA) has emerged as a powerful methodology to precisely control the morphology and size of polymer nanostructures, enabling the formation of 1D and 2D nanomaterials. Yet, the melting behavior of polymer crystals grown in solution using this technique has remained largely unexplo...

Nonlinear optical (NLO) crystals are essential for laser frequency conversion, yet rational crystal design remains challenging due to intrinsic trade-offs among key performance parameters. This review establishes a multi-scale design paradigm to unify fragmented knowledge of NLO materials by correlating microscopic, me...
