光致产酸剂 (PAG) 是一种有机化合物，在特定波长的光照射下可以产生质子 (H+)。在这项工作中，我们设计并合成了第一个基于BODIPY的具有D-A和D-pi-A共轭结构的PAG，并实现了绿色和红色LED光诱导产酸。通过使用红光吸光度，红色 LED 触发的阳离子聚合被证明是这些 PAG 的概念验证应用。
Photoacid generators (PAGs) are organic compounds that can generate protons (H+) upon irradiation with certain wavelengths of light. In this work, we designed and synthesized the first BODIPY-based PAGs with D-A and D-pi-A conjugation structures and achieved green and red LED light-induced acid generation. By the use of red-light absorbance, red-LED-triggered cationic polymerization was demonstrated as a proof-of-concept application of these PAGs.
