  聚钴肟/碳纳米管电极：具有聚合物增强析氢性能的独立式巴基纸

  摘要：

  报道了一种独立式 H 2析出电极，该电极由通过 π-π 相互作用集成到多壁碳纳米管基质中的共聚物嵌入钴肟组成。该电极组装简单，在惰性和有氧条件下，在接近中性 pH 值的溶液中表现出高析氢活性，钴基周转数 (TON Co ) 高达 420。具有单体钴肟的类似电极显示出更少的析氢活性。 TON Co仅为 80 时的活性。这些结果表明，除了巴基纸多孔网络的高表面积之外，聚合物支架还为催化剂提供了稳定的环境，从而进一步提高了催化性能。因此，我们确定使用多功能共聚物结构是增强分子电催化剂性能的可行策略。

  (2-(dimethylamino)ethyl methacrylate) polymer was synthesized through a controlled radical RAFT polymerisation approach. An average pyrene content of 3.65% was determined by UV/Vis and 1H NMR measurements. DLS measurements reveal the formation of polymer aggregates with an average size of 172 nm in aqueous phosphate buffer indicating the presence of hydrophobic interactions between pyrene and/or DMAEMA moieties of

  Terpolymers of 50 mol % sodium 2-(acrylamido)-2-methylpropanesulfonate (AMPS), 1 mol % 1-(pyrenylmethyl)methacrylamide (PyMAm), and 49 mol % lauryl- or cyclododecyl- or adamantylmethacrylamide units were synthesized. A copolymer of 99 mol % AMPS and 1 mol % PyMAm units was also prepared as a reference polymer. Charge-transfer (CT) complexation, fluorescence quenching, and photoinduced electron transfer (ET) were studied, using methylviologen (MV2+) as an acceptor. In the terpolymers, the polymer-bound pyrene (Py) chromophores are compartmentalized in hydrophobic microdomains of a micellelike microphase structure formed by the terpolymers in aqueous solution, while the chromophores are exposed to the aqueous phase in the reference copolymer. In the compartmentalized systems, the CT complexation of Py with MV2+ was suppressed, but the fluorescence quenching was enhanced. Charge recombination (CR) of the primary ion pair generated by laser excitation was slowed by an order of magnitude as compared to that in the reference copolymer system, while very fast photoinduced forward ET occurred (within ca. 20 ps). Thus, the terpolymer systems showed charge separation that persisted for hundreds of microseconds. These findings were qualitatively interpreted in terms of sterical protection of the Py chromophore from a close contact with MV2+, although MV2+ is highly concentrated on the surface of the hydrophobic microdomain of the terpolymers. A sterically hindered primary ion pair of a looser structure with a longer lifetime may be formed in the compartmentalized systems. The lauryl group was significantly less effective in protecting Py than were the cyclododecyl and adamantyl groups. A judicious choice of the hydrophobic group is suggested to achieve an optimal compartmentalization of Py, which will lead to an optimal efficiency for charge separation.
