Attributing to the advantages of high theoretical specific capacity, good structural designability and environmental friendliness, organic quinone electrode materials have been applied in secondary batteries to achieve great electrochemical performances. At present, a series of researches about secondary batteries with quinone‐based compounds calix[4]quinone (C4Q), pillar[5]quinone (P5Q) and calix[6]quinone (C6Q) as cathodes have been carried out. In this review, we systematically summarize the applications of these three types of quinone compounds in lithium‐ion batteries (LIBs), sodium‐ion batteries (SIBs), zinc‐ion batteries (ZIBs), and magnesium‐ion batteries (Mg‐ion batteries). The optimizing methods for suppressing the dissolution of organic electrode materials such as quasi‐solid‐state electrolytes, all‐solid‐state electrolytes, ionic liquid electrolytes, aqueous electrolytes and carbon immobilization are concluded. This review could provide a good guideline to improve the electrochemical performances of secondary batteries using quinone compounds as cathodes in the future.
A selective
and efficient synthesis of diaryl 1,3,5-oxadiazines
was established for the first time from simple and readily available
amidines in wet DMSO. DMSO was employed as a dual carbon synthon and
water offered the oxygen atom to construct the oxadiazine ring. The
reaction involved two new C–N and two new C–O bond formations.
Herein, the design, synthesis,and characterization of an unprecedented copolymer consisting of alternating linear and dendritic segments is described. First, a4 th-generation Hawker-type dendron with two azide groups was synthesized, followed by as tep-growth azide-alkyne "click"r eaction between the 4th-generation diazido dendron and poly(ethylene glycol) diacetylene to create the target polymers.U nequal reactivity of the functional groups was observed in the stepgrowth polymerization. The resulting copolymers,w ith alternating hydrophilic linear and hydrophobic dendritic segments, can spontaneously associate into aunique type of microphasesegregated nanorods in water.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
