【摘要】 本文报道了多氧化还原中心的含硫族元素紫罗精,并对电致变色器件(ECD)的光电特性和原位电化学光谱进行了研究。具有多组可逆氧化还原状态的含硫族元素紫罗精聚合物被用作有机锂离子电池(OLIBs)的负极材料。通过将主族元素引入到紫罗精支架中,提高了OLIBs的容量和循环能力。具有较好的导电性和不溶性的聚Te-Bn V可以插入多个锂离子,从而提高了OLIBs的性能。该文还基于含硫族元素紫罗精独特的电致变色和氧化还原特性,制备了一种柔性电致变色电池,为柔性可视电子学提供了一种很有前景的方法。更多还原

【Abstract】 A series of electron-accepting poly(chalcogenoviologens) with multiple redox centers are reported,and the photoelectric properties and in-situ electrochemical spectroscopies of electrochromic devices(ECD) are investigated. Chalcogenoviologens and poly(chalcogenoviologens) with stable and multiply reversible redox states were used as anodic materials in organic Li-ion batteries(OLIBs). The capacity and cycling stabilities of OLIBs enhanced by introduction of heavy atoms(S, Se and Te) into viologen scaffolds. The poly(Te-BnV) with better conductivity and insolubility could insert multiple Li ions, led to the higher performance of OLIBs.Based on the unique electrochromic and redox properties of poly(chalcogenoviologens), a flexible cell and electrochromic batteries were fabricated, which provided a promising strategy for flexible visual electronics.更多还原
