Tunable Quantum Photoinitiators for Radical Photopolymerization

Abstract

This review describes the use of nanocrystal-based photocatalysts as quantum photoinitiators, including semiconductor nanocrystals (e.g., metal oxides, metal sulfides, quantum dots), carbon dots, graphene-based nanohybrids, plasmonic nanocomposites with organic photoinitiators, and tunable upconverting nanocomposites. The optoelectronic properties, cross-linking behavior, and mechanism of action of quantum photoinitiators are considered. The challenges and prospects associated with the use of quantum photoinitiators for processes such as radical polymerization, reversible deactivation radical polymerization, and photoinduced atom transfer radical polymerization are reviewed. Due to their unique capabilities, we forsee a growing role for quantum photoinitiators over the coming years.

Progress of Nanomaterials in Photodynamic Therapy Against Tumor

“…Metal sulfides are often used as photothermal agents for photothermal therapy, among which Ni 3 S 2 , CuS and Co 3 S 4 nanoparticles can be used to synthesize semiconductor PSs, which is an effective way to combine PTT/CDT/PDT ( Shukla et al, 2021 ).…”

Cationic and radical polymerization using a boron–thienothiophene–triphenylamine based D–π–A type photosensitizer under white LED irradiation

“…One of the most important examples are the molecules having donor–π–acceptor (D–π–A) units with pull–push interactions to provide charge generation, mobility and stability for visible light photoinduced polymerization. 14–18…”
