Butterfly-like molecules of oxacalix[2]arene[2]pyrazine (OAP) are reported, which exhibit the typical characteristics of aggregation-induced emission (AIE) via the restriction of intramolecular vibration (RIV) mechanism. Unlike any of the reported RIV-type AIE molecules, the synthetic procedures of which are complicated and have associated high costs, OAP AIEgens can be synthesized in a facile manner by a one-step catalyst-free reaction using commercially available materials. Notably, OAP AIEgens are ideal ligands for constructing metal–organic frameworks (MOFs) due to their built-in pyrazine coordination sites. OAP-based MOFs exhibit multiple potential applications in reversible gas response, encrypted information storage, and construction of white light-emitting devices. This work builds on RIV-type AIEgens, offers additional selections of bridging ligands for constructing luminescent MOFs and provides a visualized prototype to understand the effect of the RIV process on the luminescence properties of MOFs.

聚集诱导发光发光原中分子内振动的限制：在多功能发光金属-有机框架中的应用

报道了类似蝴蝶的氧杂杯[2]芳烃[2]吡嗪( OAP )分子，其通过限制分子内振动(RIV)机制表现出聚集诱导发射(AIE)的典型特征。与任何报道的 RIV 型 AIE 分子不同，其合成程序复杂且成本高，OAP AIEgens 可以使用市售材料通过一步无催化剂反应以简便的方式合成。值得注意的是，由于其内置的吡嗪配位位点，OAP AIEgens 是构建金属有机框架 (MOF) 的理想配体。行动纲领基于 MOF 的 MOF 在可逆气体响应、加密信息存储和白光发光器件的构建方面具有多种潜在应用。这项工作建立在 RIV 型 AIEgens 的基础上，为构建发光 MOF 提供了额外的桥接配体选择，并提供了一个可视化原型，以了解 RIV 过程对 MOF 发光特性的影响。
