There is still an urgent demand for novel smart materials that can achieve a diverse range of practical applications in the synthetic material area. Herein, we developed a simple but versatile aggregation-induced emission luminogen (AIEgen, 1). Compound 1 was sensitive to an electric stimulus and displayed reversibly three-color switched electrochromism and on-to-off electroluminochromism. Such properties allowed the fabrication of high-performance non-doped OLEDs with a high external quantum efficiency of 5.22%. Due to its AIE property and remarkable sensitive color change in response to polarity change, it can serve as a unique imaging probe for detecting environmental polarity in cells and selective visualization of lipid droplets in live tissues. More impressively, compound 1 exhibited a wide range of thermoresponsive behaviors with a ratiometric luminescence change and noticeable fluorescence color switching. As another remarkable feature, it can respond to anisotropic shearing force and isotropic hydrostatic pressure with prominent and contrasting luminescence conversion due to the distinct disturbance of the weak intermolecular interactions and charge transfer process. The present results may offer an important guideline for multifunctional molecular design and provide an important step forward to expand the real-life applications of smart materials.

具有多种刺激反应行为的“简单”供体-受体AIEgen †
仍然迫切需要能够在合成材料领域实现多种实际应用的新型智能材料。在本文中，我们开发了一种简单而通用的聚集诱导发射发光素（AIEgen，1）。化合物1对电刺激敏感，并显示可逆的三色切换电致变色和开-关电致发光。这样的特性允许制造具有5.22％的高外部量子效率的高性能非掺杂OLED。由于其AIE特性和响应极性变化的显着敏感颜色变化，它可以用作检测细胞中环境极性和选择性观察活组织中脂质滴的独特成像探针。更令人印象深刻的是图1显示了具有比例发光变化和显着的荧光颜色切换的多种热响应行为。另一个显着特征是，由于弱分子间相互作用和电荷转移过程的明显扰动，它可以以显着的对比发光响应来响应各向异性的剪切力和各向同性的静水压力。目前的结果可能为多功能分子设计提供重要指导，并为扩展智能材料的实际应用提供了重要的一步。
