Crystalline cluster-assembled materials (CAMs) are emerging as types of exploratory fabrications due to their atomically precise structures and intriguing chemical/physical properties, as well as their luminescent function. However, constructing novel luminescent porous crystalline CAMs present an enduring and significant challenge owing to their instability and poor ambient-temperature photoluminescent quantum yields. In this work, we synthesized successfully, a mesoporous crystalline CAM (1⊃ DMAC), based on silver-chalcogenolate cluster and 1,1,2,2-tetrakis(4- (pyridin-4-yl)phenyl)ethene (TPPE) ligand, with highsymmetry structure and ultralarge pores. 1⊃DMAC exhibited adjustable intense luminescence, originating from aggregation-induced emission (AIE) properties of the TPPE ligand. The diameter of the cubic cage in 1⊃DMAC was as high as 32 Å, which endowed it with satisfactory encapsulation capacity for different guest molecules. Interestingly, by adjusting functionalized guest molecules, circularly polarized luminescence, white-light-emitting, and room-temperature phosphorescence were readily realized. 1⊃ DMAC could enrich limited kinds of mesoporous crystalline CAMs and offers the prospect of application in host–guest chemistry. More importantly, this work provides a strategy, versatile for tailoring luminescence in crystalline porous materials.

具有定制的光致发光特性的介孔晶体硫族硫醇银团簇组装材料

晶体簇组装材料（CAM）由于其原子上精确的结构和令人着迷的化学/物理性质以及其发光功能而成为一种探索性的制造形式。然而，由于其不稳定性和环境温度下的光致发光量子产率不佳，构造新型的发光型多孔晶体CAM面临着持久而重大的挑战。在这项工作中，我们成功地合成了一种介孔晶体CAM（1⊃DMAC），其基于硫属元素化银簇和1,1,2,2-四（4-（吡啶-4-基）苯基）乙烯（TPPE）配体，具有高对称结构和超大孔。1⊃DMAC表现出可调节的强烈发光，这是由于TPPE配体的聚集诱导发射（AIE）特性引起的。1⊃DMAC中立方笼的直径高达32Å，赋予了它对不同客体分子令人满意的包封能力。有趣的是，通过调节功能化的客体分子，圆偏振发光，发白光和室温磷光很容易实现。1⊃DMAC可以丰富有限种类的介孔晶体CAM，并提供在宿主-客体化学中的应用前景。更重要的是，这项工作提供了一种策略，可用于调整结晶金属多孔材料中的发光。1⊃DMAC可以丰富有限种类的介孔晶体CAM，并提供在宿主-客体化学中的应用前景。更重要的是，这项工作提供了一种策略，可用于调整结晶金属多孔材料中的发光。1⊃DMAC可以丰富有限种类的介孔晶体CAM，并提供在宿主-客体化学中的应用前景。更重要的是，这项工作提供了一种策略，可用于调整结晶金属多孔材料中的发光。
