In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called BODIPY-based photoacid generators for light-induced cationic polymerization, published in 2020-02-07, which mentions a compound: 625-82-1, mainly applied to photoacid generator cationic photopolymerization bodipy ROMP, Recommanded Product: 2,4-Dimethyl-1H-pyrrole.
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-π-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.
There are many compounds similar to this compound(625-82-1)Recommanded Product: 2,4-Dimethyl-1H-pyrrole. if you want to know more, you can check out my other articles. I hope it will help you，maybe you’ll find some useful information.
