Three D−A compounds were designed and synthesized based on a benzothiadiazole acceptor. Azepane (AP), iminodubenzyl (IDB) and iminostilbene (ISB) were used, respectively, as donors and installed on the 5‐position of BTD to afford 1, 2 and 3, respectively. Their photophysical properties in different states (solution, film, crystal, and powder) are systematically investigated. Among them, AIE‐active compounds 2 and 3 were found to have good sensitivity toward viscosity and display quite good linear relationship with an increase in viscosity. Compound 2 displayed dual emission in solutions which largely depended on the polarity of the solvent. Meanwhile, compound 2 exhibits a mechanochromic character with disappearance and reappearance of a dual‐emissive peak induced by mechanical grinding and solvent fuming. Furthermore, these three compounds can be used in the fabrication of blue OLED devices.

三种5-氨基苯并噻二唑（5-amBTDs）的制备及光致发光性能。

基于苯并噻二唑受体设计并合成了三种D-A化合物。氮杂环庚烷（AP），iminodubenzyl（IDB）和氨基芪（ISB）分别使用，作为供体和安装在BTD的5位，得到1，2和3分别。系统地研究了它们在不同状态（溶液，薄膜，晶体和粉末）下的光物理性质。其中，发现AIE活性化合物2和3对粘度具有良好的敏感性，并且随着粘度的增加显示出很好的线性关系。化合物2在溶液中显示双重发射，这在很大程度上取决于溶剂的极性。同时，化合物2表现出机械变色特性，由机械研磨和溶剂发烟引起的双发射峰消失并重新出现。此外，这三种化合物可用于制造蓝色OLED器件。
