Solution and solid dual photoluminescence (PL) molecules fill the substantial gap between ACQ and AIE molecules to explore the mechanism of molecular luminescence in greater detail and to facilitate practical applications. A unique arch-bridge-like thiazolo[5,4-]thieno[3,2-]pyridine moiety is obtained as a stator after the rigidification of rotor 1 by intramolecular H-bonding of -OH or -NH to afford two classes of solid and solution dual PL molecules. As a typical example, is dual PL active. Moreover, the large Stokes shift with high dual PL efficiency ( up to 51% in the solid state, 80% in DMF, 74% in DMSO, and 100% in water), together with the good thermal stability ( > 200 °C and > 200 °C), make it more practical for promising optoelectronic and biological applications.
溶液态和固态双光致发光（PL）分子填补了聚集猝灭（ACQ）和聚集诱导发光（AIE）分子之间的巨大空白，以便更详细地探索分子发光机制并促进实际应用。通过 -OH 或 -NH 的分子内氢键作用使转子 1 刚性化后，得到了一种独特的类拱桥状噻唑并[5,4-]噻吩并[3,2-]吡啶部分作为定子，从而得到两类固态和溶液态双 PL 分子。作为一个典型例子， 具有双 PL 活性。此外，大斯托克斯位移和高双 PL 效率（固态高达 51%，DMF 中为 80%，DMSO 中为 74%，水中为 100%），以及良好的热稳定性（>200 °C 和 >200 °C），使其在有前景的光电和生物应用中更具实用性。
