Janus-type diiridium complexes with functional carbene cyclometalates for high-energy phosphorescence

Guowei Ni, Yi Pan, Kai‐Chung Lau, Yün Chi

We synthesized four diiridium Janus carbene complexes, exhibiting emissions ranging from 422 nm to 451 nm with high photoluminescent quantum yields (PLQYs) of 44%–78%. These photophysical characteristics were verified using TD-DFT calculations.

Red and Near Infrared Emissive Bis‐Tridentate Ir(III) Phosphors for Organic Light Emitting Diodes

Jie Yan, Min Song, Dong‐Ying Zhou, Guowei Ni et autres

Abstract Efficient saturated red and near‐infrared (NIR) emissive materials are needed in the development of organic light‐emitting diodes (OLEDs), with applications extending beyond flat panel displays and lighting luminaries. Toward this aim, a series of bis‐tridentate Ir(III) complexes (3a ‒ 3c and …

Asymmetric Synthesis of Florfenicol by Dynamic Reductive Kinetic Resolution with Ketoreductases

Jie Zou, Guowei Ni, Jiawei Tang, Jun Yu et autres

A chemoenzymatic synthesis of the veterinary antibiotic florfenicol is described. The key step involves the dynamic reductive kinetic resolution (DYRKR) of a keto ester by using a ketoreductase‐02 (KRED‐02) to afford the two contiguous stereocenters of the (2S,3R)‐cis‐1,2‐amino alcohol intermediate in >99 …
