Benefiting from the diversity and subjective design feasibility of molecular structure, flexibility,lightweight, molecular level controllability, resource renewability and relatively low cost, polymeric electrode materials are promising candidates for the next generation of sustainable energy resources and have attracted extensive attention for the foreseeable large scale applications. The conductive polymers have been utilized as electrode materials in the pioneer reports, which, however, have the disadvantages of low stability, low reversibility and slope voltage due to the delocalization of charges in the whole conjugated systems. The discovery of carbonyl materials aroused the interest of organic and polymeric materials for batteries again. This review presents the recent progress in carbonyl polymeric electrode materials for lithium-ion batteries, sodium-ion batteries and magnesium-ion batteries. This comprehensive review is expected to be helpful forarousing more interest of organic materials for met

The organic single-crystal field-effect transistors using anthracene derivative, H-Ant as an active layer with source/drain electrodes decorated by metal charge transfer salt(Cu TCNQ) were fabricated. We demonstrated that this bottom-contact structure displayed an obvious improvement in the electrical characteristics relative to their pristine copper and top-contact gold electrode counterparts. This observation could be ascribed to the lower contact resistance resulting from the energetic match between electrodes and semiconductor.
