In this work, a kind of chiral helical polymer PDTDH of 9,9-dipropynylfluorene skeleton structure were prepared. The structure and chiral properties of the obtained polymer were characterized by Nuclear Magnetic Resonance (NMR) and Circular Dichroism (CD) Spectroscopy. These chiral PDTDH polymers were used to fabricate chiral sensors and to investigate the enantioselective recognition of D−/L- tartaric acid enatiomer. The results indicated that the (S)-PDTDH/GCE sensor showed obvious response toward the tested tartaric acid enantiomer, which was confirmed by two parameters: Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) tests. These findings expand the scope for the application of chiral polymer as electrode modification material in the electrochemical chiral recognition field.

在这项工作中，制备了一种9,9-二丙炔基芴骨架结构的手性螺旋聚合物PDDTH。通过核磁共振（NMR）和圆二色性（CD）光谱表征了所得聚合物的结构和手性。这些手性PDDTH聚合物用于制造手性传感器，并研究D- / L-酒石酸对映体的对映选择性识别。结果表明，（S）-PDTDH / GCE传感器对所测试的酒石酸对映体表现出明显的响应，这可以通过两个参数来证实：循环伏安法（CV）和微分脉冲伏安法（DPV）测试。这些发现扩大了手性聚合物在电化学手性识别领域中作为电极改性材料的应用范围。
