In continuation of the first funding phase, this project aims at combining synthetic and electrochemical expertise to drive the development of new small redox-active organic molecules based on squaric acid amide derivatives and their incorporation within polymers. Yet, to improve the performance and in particular their energy density, new types of condensed redox-active squaric acid quinoxaline (SQX) molecules will be investigated to extend the class of redox-active polymers suitable as materials for electrochemical energy storage. This will include: (i) introducing more sophisticated 2D or even 3D architectures into the SQX molecules, (ii) gaining deeper insights into the effects of π stacking by designing novel extended aromatic SQX molecules, (iii) investigating the effect of Lewis acid coordination to the carbonyl groups of SQX, (iv) dehydrogenative oxidation of SQX to form squaric acid quinoxaline derived anode materials, (v) expanding the structural motif of squaric acids by one or two (CO) units and investigate the corresponding amides of croconic and rhodizonic acid, (vi) subsequent design of monomers and their polymerization, (vii) synthesis of redox-active molecules suitable for post-polymerization modification, (viii) synthesis of redox-active molecules suitable for cross-linked films, (ix) the careful electrochemical evaluation of the redox-active molecules, (x) optimization of the electrolyte composition for the most promising active materials, (xi) development of advanced electrode architectures, (xii) realization of electrodes with an increased active material mass loading, and (xiii) the assembly of fully organic battery cells.

在第一个资助阶段的延续中，该项目旨在结合合成和电化学专业知识，以推动基于方酸酰胺衍生物的新型小氧化还原活性有机分子的开发及其在聚合物中的结合。然而，为了提高性能，特别是它们的能量密度，将研究新型的缩合氧化还原活性方酸喹喔啉（SQX）分子以扩展适合作为电化学能量存储材料的氧化还原活性聚合物的类别。这将包括：（i）在SQX分子中引入更复杂的2D或甚至3D结构，（ii）通过设计新的扩展芳族SQX分子获得对π堆积效应的更深入了解，（iii）研究刘易斯酸配位对SQX的羰基的影响，（iv）SQX的还原氧化以形成方酸喹喔啉衍生的阳极材料，（v）通过一个或两个（CO）单元扩展方酸的结构基序，并研究相应的克酮酸和玫棕酸的酰胺，（vi）单体的后续设计及其聚合，（vii）适合于聚合后改性的氧化还原活性分子的合成，（viii）适合于交联膜的氧化还原活性分子的合成，（ix）氧化还原活性分子的仔细电化学评价，（x）最优化电解质组合物以获得最有希望的活性材料，（xi）先进电极结构的开发，（xii）实现具有增加的活性材料质量负载的电极，和（xiii）组装全有机电池组电池。
