Supracluster assembly offers a unique opportunity for the isolation of customized materials using functional cluster precursors. Herein, for the first time, we demonstrate supracluster assembly based on an Al₄⁴⁻ precursor through both non-covalent interactions and coordination bonds. By reacting readily available, ultrastable, and soluble Al₄⁴⁻ as an anionic precursor with a metal center and neutral chelated chromophores, we successfully synthesized an extensive library of supracluster assembled crystalline solids, ranging from ion-pair structures, surface-modified clusters, and chains, to layered compounds. The advantage of this method is that it achieves stepwise performance regulation and enhancement using given functional precursors. These materials from supracluster assembly possess a broad range of tunable photophysical properties, including photoluminescence and third-order nonlinear optical (NLO) properties. Such extraordinary supracluster assembly will be widely applicable for creating a new generation of rationally organized solid materials with tailorable and customized properties.

Al4 前驱体的超团簇组装，用于研究增强的光学性能


超团簇组装为使用功能团簇前体分离定制材料提供了独特的机会。在此，我们首次证明了通过非共价相互作用和配位键基于 Al ₄ ⁴⁻ 前体的超簇组装。通过将容易获得、超稳定且可溶的 Al ₄ ⁴⁻ 作为阴离子前体与金属中心和中性螯合发色团反应，我们成功合成了广泛的超簇组装结晶固体库，范围包括从离子对结构、表面改性簇和链，到层状化合物。该方法的优点是它使用给定的功能前体实现了逐步的性能调节和增强。这些来自超簇组装的材料具有广泛的可调谐光物理性质，包括光致发光和三阶非线性光学（NLO）性质。这种非凡的超簇组装将广泛应用于创造具有可定制和定制特性的新一代合理组织的固体材料。
