Two types of aggregation−induced emission (AIE) stereolithography resins have been prepared. The AIE thermoset photocurable resin is made by covalently crosslinking of tetrakis (4–aminophenyl) ethene, bisphenol F epoxy resin (BPF) and methylacrylic acid (MAA). However, the AIE thermoplastic photocurable resin with “OFF–ON” fluorescence response is prepared by doping the AIE luminogens to the polymers rather than covalently crosslinking. The 3D printing process of these photopolymers can be continuously monitored according to the change of the fluorescence intensity for the first time. Before printing, the solution is non−fluorescent, during the printing process, fluorescence appears because aggregation of AIE moieties, and the printed objects are highly fluorescent after photosetting. So, this work offers an important tool for measuring printing and photo−curing processes. Furthermore, the colorful models can be obtained by mixing and curing them in different proportions just like mixing pigments and the fluorescence has also been found sensitive to the phase transitions (e.g., glass transition temperature, T_g) of materials. Finally, the curing process of the prepared AIE stereolithography resins is helpful to understand the AIE mechanism and have a potential to expand the application of the AIE molecules.

已经制备了两种类型的聚集诱导发射（AIE）立体光刻树脂。AIE热固性光固化树脂是通过四（4-氨基苯基）乙烯，双酚F环氧树脂（BPF）和甲基丙烯酸（MAA）共价交联而成的。但是，具有“ OFF-ON”荧光响应的AIE热塑性光固化树脂是通过将AIE发光剂掺杂到聚合物中而不是共价交联制备的。这些光敏聚合物的3D打印过程可以首次根据荧光强度的变化进行连续监控。在打印之前，溶液是非荧光的，在打印过程中，由于AIE部分的聚集而出现了荧光，并且在光固化后，打印的对象是高度荧光的。所以，这项工作为测量打印和光固化过程提供了重要的工具。此外，可以通过以不同比例混合和固化它们来获得彩色模型，就像混合颜料一样，而且还发现荧光对相变（例如玻璃化转变温度，T_g）材料。最后，所制备的AIE立体光刻树脂的固化过程有助于理解AIE机理，并具有扩大AIE分子应用的潜力。
