Multi‐N‐Heterocycle Donor‐Acceptor Conjugated Amphoteric Organic Superstructures for Superior Zinc Batteries

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 5, 2024

Abstract Multiple redox‐active amphoteric organics with more n‐p fused electron transfer is an ongoing pursuit for superior zinc–organic batteries (ZOBs). Here we report multi‐heterocycle‐site donor‐acceptor conjugated organic superstructures (AOSs) by integrating three‐electron‐accepting n‐type triazine motifs and dual‐electron‐donating p‐type piperazine units via H‐bonding π–π stacking. AOSs expose flower‐shaped N‐heteromacrocyclic delocalization topologies to promise full accessibility of built‐in ultralow activation energy, thus liberating capacity (465 mAh g −1 ) Zn||AOSs battery. More importantly, the extended multiple donor‐acceptor‐fused feature satisfied discharge voltage anti‐dissolution in electrolytes, pushing both energy density cycle life ZOBs a new level (412 Wh kg 70,000 cycles@10 A ). An anion–cation hybrid 18 e − charge storage mechanism rationalized heteromacrocyclic modules cathode, entailing six tert‐N coupling CF 3 SO ions at high potential twelve imine sites coordinating Zn 2+ low potential. These findings constitute major advance multielectron materials stand good starting point advanced ZOBs.
