Abstract
NIR‐sensitized cationic polymerization proceeded with good efficiency, as was demonstrated with epoxides, vinyl ether, and oxetane. A heptacyanine functioned as sensitizer while iodonium salt served as coinitiator. The anion adopts a special function in a series selected from fluorinated phosphates (a: [PF6]−, b: [PF3(C2F5)3]−, c: [PF3(n‐C4F9)3]−), aluminates (d: [Al(O‐t‐C4F9)4]−, e: [Al(O(C3F6)CH3)4]−), and methide [C(O‐SO2CF3)3]− (f). Vinyl ether showed the best cationic polymerization efficiency followed by oxetanes and oxiranes. DFT calculations provided a rough pattern regarding the electrostatic potential of each anion where d showed a better reactivity than e and b. Formation of interpenetrating polymer networks (IPNs) using trimethylpropane triacrylate and epoxides proceeded in the case of NIR‐sensitized polymerization where anion d served as counter ion in the initiator system. No IPN was formed by UV‐LED initiation using the same monomers but thioxanthone/iodonium salt as photoinitiator. Exposure was carried out with new NIR‐LED devices emitting at either 805 or 870 nm.

Abstract
In this work, a high performance LED photoinitiator, 1,3-bis(1-methyl-1H-pyrrol-2-yl)prop-2-en-1-one (BMO), without a benzene ring was synthesized through a one-step aldehyde–ketone condensation reaction.
