Amplified circularly polarized phosphorescence from co-assemblies of platinum(ii) complexes

Autor: Youngmin You, Hoichang Yang, Hyungchae Kim, Kyung Ryoul Park, Joon Hak Oh, Changsoon Kim, Inho Song, Gyurim Park

Publikováno v: Chemical Science. 10:1294-1301

Molecules capable of producing zero-field circularly polarized phosphorescence (CPP) are highly valuable for chiroptoelectronic applications that rely on triplet exciton. However, the paucity of tractable molecular design rules for obtaining CPP emis

Publikováno v: Chemical Science

Polymer electroluminescence devices producing circularly polarized luminescence (CP PLEDs) have valuable photonic applications. The fabrication of a CP PLED requires a polymer host that provides the appropriate chiral environment around the emitting

Monocycloplatinated Solvento Complex Displays Turn-on Ratiometric Phosphorescence Responses to Histamine

Autor: Youngmin You, Ahjeong Son, Yoonseo Nah, Sinheui Kim, Gyurim Park, Seungyeon Yu

Publikováno v: Inorganic Chemistry. 57:13985-13997

The study of biological histamine (HA) requires probes capable of ratiometric photoluminescence detection of HA. We discovered that a monocycloplatinated complex having two solvento ligands ([Pt(2-(2-naphthyl)quinolinate)(NCCH

Photocatalytic function of the B12 complex with the cyclometalated iridium(iii) complex as a photosensitizer under visible light irradiation

Autor: Gyurim Park, Youngmin You, Hisashi Shimakoshi, Sinheui Kim, Hui Tian, Yoshio Hisaeda

Publikováno v: Dalton Transactions. 47:675-683

A visible light induced three-component catalytic system with the cobalamin derivative (B12) as a catalyst, the cyclometalated iridium(iii) complex (Irdfppy, Irppy, Irpbt and [Ir{dF(CF3)ppy}2(dtbpy)]PF6) as a photosensitizer and triethanolamine as an

Mechanism and Applications of the Photoredox Catalytic Coupling of Benzyl Bromides

Autor: Eun Jin Cho, Youngmin You, Gyurim Park, Seung Yeon Yi, Jaehun Jung

Publikováno v: Chemistry - A European Journal. 22:17790-17799

The photoredox catalytic coupling of halomethyl arenes to bibenzyl derivatives has been demonstrated. The catalytic protocol employed the Hantzsch ester, potassium phosphate, and a photoactive cyclometalated IrIII complex catalyst. A photochemical qu

Coreactant Strategy for the Photoredox Catalytic Generation of Trifluoromethyl Radicals under Low-Energy Photoirradiation

Autor: Eun Jin Cho, Gyurim Park, Youngmin You, Sinheui Kim

Publikováno v: The Journal of Organic Chemistry. 81:7072-7079

Photoredox catalysis has emerged as a valuable alternative to dark-state catalysis. For the full potential of photoredox catalysis to be utilized, it is imperative to make use of low-energy photons in photoinduced radical processes. We have demonstra

Selective Debromination and α-Hydroxylation of α-Bromo Ketones Using Hantzsch Esters as Photoreductants

Autor: Youngmin You, Eun Jin Cho, Gyurim Park, Jaehun Jung, Jun Kim

Publikováno v: Advanced Synthesis & Catalysis. 358:74-80

Two transformations initiated by photoinduced one-electron transfer to α-bromo ketones have been demonstrated. Hantzsch esters donate one electron to α-bromo ketones under photoirradiation, promoting reductive debromination. Subsequent reactions of
