enhance the thermoelectric performance of n-type materials include optimizing the electron affinity (EA) with respect to the dopant to improve the doping process and increasing the charge carrier mobility through enhanced molecular packing. Here, we report the design, synthesis and characterization of fused electron-deficient n-type copolymers incorporating the electron withdrawing lactone unit along the
N型半导体聚合物近来已用于热电器件中,但是与性能高得多的p型半导体相反,它们通常表现出低电导率和差的器件稳定性。这尤其是由于n型半导体的低掺杂效率和较差的电荷载流子迁移率。增强n型材料热电性能的策略包括针对掺杂剂优化电子亲和力(EA),以改善掺杂过程并通过增强分子堆积来提高电荷载流子迁移率。在这里,我们报告了融合,缺乏电子的n型共聚物的设计,合成和表征结合沿骨架的吸电子内酯单元。使用无金属的醛醇缩合条件合成了聚合物,以探索将中心苯环扩大为萘环对电导率的影响。当n掺杂N-DMBI时,电导率高达0.28 S cm从具有-4.68eV的最大电子亲和力的聚合物中观察到-1的塞贝克系数为-75μVK -1和最大功率因数为0.16μWm -1 K -2。延伸芳环降低了电子亲和力,这是因为降低了吸电子基团的密度,随后电导率降低了近两个数量级。

Investigating the backbone conformation and configuration effects for donor–acceptor conjugated polymers with ladder-type structures synthesized through Aldol polycondensation
and P3 with low surface roughness and high brittleness. The combined low conformation and configuration regularity account for the inferior mobility of P1. On the contrary, P2–P4 exhibit comparable hole mobility ranging from 10−2–10−3 cm2 V−1 s−1 and up to 0.011 cm2 V−1 s−1 (P2), due to their better regularity in both conformation and configuration. Collectively, our results provide a new perspective

N‐typeconjugatedpolymers as the semiconducting component of organic electrochemical transistors (OECTs) are still undeveloped with respect to their p‐type counterparts. Herein, we report two rigidn‐typeconjugatedpolymers bearing oligo(ethylene glycol) (OEG) side chains, PgNaN and PgNgN, which demonstrated an essentially torsion‐free π‐conjugatedbackbone. The planarity and electron‐deficient rigid
相对于p型对应物,作为有机电化学晶体管(OECT)的半导体成分的N型共轭聚合物仍未开发。在这里,我们报道了两个带有寡聚乙二醇(OEG)侧链的刚性n型共轭聚合物PgNaN和PgNgN,它们证明了基本无扭转的π共轭骨架。平面性和电子不足的刚性结构使所得的聚合物能够在高达10 -3 cm 2 V -1 s -1范围的OECT装置中实现高电子迁移率,而深层的LUMO能级低于-4.0 eV。突出地,聚合物表现出高器件性能,最大尺寸归一化跨导为0.212 S cm -1电荷载流子迁移率μ与体积电容C *的乘积为0.662±0.113 F cm -1 V -1 s -1,是迄今为止报道的n型共轭聚合物中最高的。此外,这些聚合物是通过无金属的醛醇缩合聚合反应合成的,这有利于它们在生物电子学中的应用。
