2,2'-Bis[2-(5,2'-bithienyl)]-3,3'-bithianaphthene oligomers are a model case of electroactive films endowed with "inherent chirality", originating from a stereogenic element coinciding with the whole electroactive backbone, thus resulting in impressive manifestations. This study highlights their applicative potentialities as low-cost and easy-to-prepare artificial enantiopure electrode surfaces, which display an unprecedented ability to pronouncedly separate voltammetry peaks of enantiomers of quite different chiral probes of applicative interest, concurrently with linear dynamic ranges for peak currents, affording enantiomer excess determination. Thus inherently chiral enantiopure electrodes can indeed be regarded as a key to chiral voltammetry.
2,2'-双[2-(5,2'-联噻吩)]-3,3'-联噻萘低聚物是具有“固有手性”的电活性薄膜的一个典型例子，其源于与整个电活性主链重合的手性中心，从而产生了令人印象深刻的表现。本研究强调了它们作为低成本且易于制备的人工对映体纯电极表面的应用潜力，这种电极表面具有前所未有的能力，能够显著分离多种具有应用价值的不同手性探针的对映体的伏安峰，同时具有峰电流的线性动态范围，可用于对映体过量的测定。因此，固有手性的对映体纯电极确实可被视为手性伏安法的关键。
