A novel reversible-deactivation radical polymerization strategy via near-infrared light-controlled photothermal conversion dividing wall-type heat exchanger

Thermo-sensitive hydrogels for forward osmosis with NIR light-induced freshwater recovery

“…It also has the advantages of flexible structural design and easy synthesis, which makes it a promising photothermal conversion material and has been widely used in many fields. 34,40,41 As mentioned above, the core part of the hybrid hydrogel we synthesized lies in croconaine dye-doped silica nanoparticles (NIR-800@SiO 2 NPs. ), which were prepared with silica as the shell and croconaine dye NIR-800 as the core.…”

Unimolecular micelles from star-shaped block polymers by photocontrolled BIT-RDRP for PTT/PDT synergistic therapy

“…42 A porphyrin-based initiator was also previously designed to systematically explore its regulated photocontrolled polymerization in our group, and a series of porphyrin-based star block polymers with controllable distribution were conveniently yet efficiently prepared. 43 Ketocyanine, a photothermal conversion dye with strong near-infrared (NIR) absorption, 44 can efficiently convert the absorbed light into heat under the irradiation of light at about 810 nm, which has been applied in various fields such as optical devices, 45 infrared imaging, [46][47][48] and photothermal therapy. 49,50 Employing organic photosensitizer is beneficial to overcome the defects of inorganic nanomaterials, which are currently the mainstream materials for optical therapeutic applications, such as poor biocompatibility and metabolism difficulties in vivo.…”

Persistent Radical Anions: Efficient Catalysts for Iodine-Mediated Reversible-Deactivation Radical Polymerization Driven by NIR LED Light

“…Furthermore, PCs with NIR absorption are usually expensive, difficult to synthesize and poor solubility in common solvents. Generally, upconversion and photothermal conversion are other two strategies mainly adopted to realize the behavior of polymerization by converting low-energy NIR light into high-energy heat or photons. − However, these protocols would weaken the advantages of NIR light in terms of safety and spatiotemporal control. Therefore, the selection of PIs that could be activated easily by NIR light with uncontaminated catalysts is the most rewarding also challenging too.…”
