Four isostructural coordination polymer crystals having different metal ions were synthesized and studied for ball milling-induced glass formation. Distinct glass formation was discussed from crystal structures. Doping of molecules for CP glass during the milling was demonstrated, and it resulted in tunable glass properties (Tg and Tc) and enhancement of anhydrous H+ conductivity.
A new design strategy for the high-performance organic cathode-active materials of lithium-ion batteries is presented, which involves the assembly of redox-active organic molecules with a crystalline porous structure.
Hexaazatriphenylene (HAT) derivatives have attracted wide attention because of their electron‐deficient nature and unique self‐assembly properties. In this work, a facile synthesis method for obtaining HAT derivatives with alternating electron‐withdrawing nitrile and electron‐donating alkoxy groups (HATCNOCn) is proposed. Crystal structure analysis indicated that HATCNOCn forms a one‐dimensional columnar structure via strong π–π interactions. Density functional theory calculations revealed that the edge of HATCNOCn is divided into positively and negatively charged sites owing to the presence of alternating nitrile and alkoxy groups, which would induce strong π–π interactions. Thermal analysis and polarizing optical microscopy revealed that HATCNOCn exhibits columnar liquid‐crystal phases. Time‐resolved microwave conductivity measurements further demonstrated the photoconductive nature of HATCNOCn. The proposed strategy could provide a new strategy for the design of novel organic semiconductive materials.
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.
