Holographic characterization of chain photopolymerization [PDF]
A holographic characterization technique is developed in accordance with a general photopolymerization model. The technique allows detailed quantification of the chemical parameters, including their variation from the Trommsdorff effect.

Upconversion Nanoparticle‐Assisted Photopolymerization [PDF]
Abstract Near‐infrared (NIR) laser has deeper penetration and lower thermal effect compared with ultraviolet–visible (UV/vis) laser. NIR laser can stimulate upconversion nanoparticles (UCNPs) to emit UV/vis light efficiently. Therefore, the UCNPs become an important kind of materials to produce upconversion luminescence through NIR laser.

Photopolymerization of electroactive film applied to full polymer electrochromic device
Electroactive films of thiophene-acrylate polymers were simultaneously photopolymerized by means of ultraviolet (UV) irradiation using diphenyliodonium hexafluorophosphate and acrylate special photoinitiators (PIs) as a mixed photoinitiator.

Design of Iodonium Salts for UV or Near-UV LEDs for Photoacid Generator and Polymerization Purposes
Iodonium salts are well established photoacid generators, cationic photoinitiators, as well as additives commonly used in photoredox catalytic cycles. However, as a strong limitation, iodonium salts are characterized by low light absorption properties ...
