由于大多数CP的水不溶性，在导电水凝胶中使用π-共轭聚合物（CP）仍然具有挑战性。共轭聚电解质（CPE）是有前途的替代品，因为它们具有可调的电子性质和高水溶性，但它们通常难以合成，因此没有被广泛采用。在此，我们报告的合成阴离子聚（环戊二烯基亚乙烯基）（aPCPV）从绝缘前体在温和的条件下，高产率。官能化aPCPV是一种高度水溶性的CPE，表现出低细胞毒性，我们发现，掺杂aPCPV的水凝胶赋予导电性。我们还预计，这种前体合成策略，由于其简单和高效，将被广泛用于创建尚未开发的π-共轭亚乙烯基聚合物的家庭。
The use of π-conjugated polymers (CPs) in conductive hydrogels remains challenging due to the water-insoluble nature of most CPs. Conjugated polyelectrolytes (CPEs) are promising alternatives because they have tunable electronic properties and high water-solubility, but they are often difficult to synthesize and thus have not been widely adopted. Herein, we report the synthesis of an anionic poly(cyclopentadienylene vinylene) (aPCPV) from an insulating precursor under mild conditions and in high yield. Functionalized aPCPV is a highly water-soluble CPE that exhibits low cytotoxicity, and we found that doping hydrogels with aPCPV imparts conductivity. We also anticipate that this precursor synthetic strategy, due to its ease and high efficiency, will be widely used to create families of not-yet-explored π-conjugated vinylene polymers.
