Synthesis, Optical and Singlet Oxygen Generation Properties of Phenazinone‐Based Photosensitizer with 5‐Formyl‐2‐Thienyl Substituents

Asian Journal of Organic Chemistry, EarlyView.
Phenazinone chromophore incorporating a carbonyl group into the skeleton is recently found to be a new‐type halogen‐atom‐free‐photosensitizer possessing superior ability in singlet oxygen (1O2) generation. In this work, we have designed and developed the derivative with two 5‐formyl‐2‐thienyl substituents which is expected to lead to improvement of the

Synthesis of a Molecular Tweezer Based on Norbornadiene Framework: Unexpected Stereoselectivity

Asian Journal of Organic Chemistry, EarlyView.
A new type of Klarner's molecular tweezer was synthesized through annulation of an α‐amino ketone. Surprisingly, the reaction takes place stereoselectivity though the initial amino ketone is racemic. This tweezer comprises two near‐parallel flat aromatic rings as pincers, each bearing two methyl ester groups, and a pyrazine unit as the tether ...

Design Strategies Based on Electronic Interactions for Effective Catalysts in Lithium–Sulfur Batteries

Angewandte Chemie, EarlyView.
Design of effective bidirectional electrocatalyst focused on electronic interactions in lithium–sulfur batteries. Development of effective bidirectional catalyst is essential for high‐energy density and long‐life lithium–sulfur batteries. The catalytic activity of catalyst is directly related to the degree of the interaction between the catalysts and ...

Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis

Asian Journal of Organic Chemistry, EarlyView.
This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.

Pyrazine‐Embedded 2D Conjugated Metal–Organic Framework with Quasi‐Honeycomb Lattice for High‐Capacitance Lithium‐Ion Storage

Angewandte Chemie, EarlyView.
A Cu‐OHDDQP 2D conjugated metal–organic framework (2D c‐MOF) was synthesized possessing a unique quasi‐honeycomb topology, from a pyrazine‐fused, D2‐symmetric ligand. The achieved 2D c‐MOF electrode displayed a remarkable gravimetric capacitance up to 452 A g−1 for electrochemical lithium storage.

Diglycerides of Natural Phenols and Organic Acids for Enhanced Biological Activities

Asian Journal of Organic Chemistry, EarlyView.
Diglycerides of natural organic acids and phenols were synthesized regio‐selectively. Diglycerides are structurally similar to cell membranes and are expected to exhibit cell affinity and permeability. The flexible glycerol linkers allow the diglycerides to exhibit not only the physiological activities of each constituent organic acid but also the ...
