In 2022,Wu, Yimei; Simpson, M. Cather; Jin, Jianyong published an article in ChemistrySelect. The title of the article was 《A 3D Printing of Thiol-Yne Photoresins through Visible Light Photoredox Catalysis》.Related Products of 94928-86-6 The author mentioned the following in the article:
In this work, we report a visible light active thiol-yne photoresin formulation that is printable with digital light processing (DLP) 3D printer under irradiation of blue-light (λmax=470 nm). The resulting objects have the Z axis resolution of 250μm (layer thickness) and building speed of (5 mm/h). Uniquely, our thiol-yne photoresin contains photoredox catalysts Eosin Y and fac-Ir(ppy)3, which initiate the photopolymerization through a photoredox mechanism. The optimized dual catalysts EY/fac-Ir(ppy)3 system not only facilitate the faster thiol-yne reaction but also potentially enables wider visible light wavelength coverage for 3D printing process. This work illustrates the possibility of replacing traditional photoinitiator with photoredox catalysts in the visible light range, thus, enriching the photoresin formulations for polymer-based 3D printing industry. The experimental part of the paper was very detailed, including the reaction process of fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Related Products of 94928-86-6)
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. Related Products of 94928-86-6
