“…In addition, as can be seen from the spectrum of TTD-PDA, there are no saturated C–H bonds in TTD-PDA, which is consistent with our expected result. Also, it is worth mentioning that the position of absorption peak of unsaturated C–H bond in TTD-PDA showed obvious blueshift (2873 cm –1 ) compared with the other two substances, which was probably caused by the adjacent benzene rings that have an electron donating conjugation effect − (Figure a). All of these results indicated that the TTD-PDA, TTD-EDA, and GA-PDA were successfully prepared.…”

In recent years, organic materials have been increasingly studied as anode materials in lithium-ion batteries (LIBs) due to their remarkable advantages, including abundant raw materials, low prices, diverse structures, and high theoretical capacity. In this paper, three types of aromatic Schiff-base polymer materials have been synthesized and examined as anode materials in LIBs. Among them, the polymer [C 6 H 4 N = CHC 6 H 4 CH�N] n (TTD-PDA) has a continuous conjugated backbone (label as conjugated polymer), while polymers [(CH 2 ) 2 N�CHC 6 H 4 CH�N] n (TTD-EDA) and [C 6 H 4 N�CH(CH 2 ) 3 CH�N] n (GA-PDA) have discontinuous conjugated back-bones (label as nonconjugated polymer). The organic anodes based on TTD-PDA, TTD-EDA, and GA-PDA for LIBs are discovered to represent high reversible specific capacities of 651, 492, and 416 mAh g −1 at a current density of 100 mA g −1 as well as satisfactory rate capabilities with high capacities of 210, 90, and 178 mAh g −1 and 105, 57, and 122 mAh g −1 at current densities of 2 and 10 A g −1 , indicating that these Schiff-base polymers are all promising anode materials for LIBs, which broadens the design of organic anode materials with high specific capacity, superior rate performance, and stable cycling stability.
