  Organic surface modification using stable conducting materials

  摘要：

  通过使用稳定导电材料，如经OBT功能化的聚噻吩，实现了氨基酸和有机分子在导电表面上的高效固定化方法，这种方法便于在导电和半导电表面上引入特定结构基元。通过保护羧酸、接着进行Stille交叉偶联反应、酸脱保护及利用HOBT（羟基苯并三唑）和EDC酯化，完成了电聚合单体的合成。该单体对应的聚合物5（聚合物5–铂）在铂电极上表现出优异的稳定性，如循环伏安法所示，允许在功能化聚合物表面引入多种氨基酸和有机分子。经修饰的表面（聚合物6–铂）通过ATR红外光谱表征，显示出对应于氨基酸酰胺的羰基伸缩振动。

  2′′-terthiophene (TBA) and 3′-(carboxylic acid)-2,2′:5′,2′′-terthiophene (TCA) were synthesized and polymerized with as-prepared GO to form complexes by a potential cycling method. The aminopyrimidyl groups on the poly(APT) backbone served as effective functional groups in the oxygen reduction reaction. The APT–GO complex was formed through hydrogen bonding and a ring-opening reaction of the epoxide group with

• Thiophene-Based Conjugated Polymers with Photolabile Solubilizing Side Chains

  This paper describes a series of thiophene-based conjugated polymers that become insoluble upon irradiation with ultraviolet light. Stille or Suzuki reactions of appropriately substituted 2,5-bromothiophene derivatives yielded terthiophene and polythiophene derivatives with either o-nitrobenzyl (ONB) ester or ONB ether photolabile side chains with n-octyl substituents. Light-induced cleavage of these ONB side chains with ultraviolet light at 365 nm cleaves the octyl chains responsible for solubilization of the polymers away from the conjugated main chains, rendering them insoluble. Consistent with the accepted mechanism of ONB photolysis, those structural modifications that would yield a more stable benzylic radicalmethyl substitution on the benzylic position, replacement of the ester with an ether, or bothyielded more efficient photolyses as determined by (i) quantum yields of photolysis of ONB-substituted terthiophenes, and (ii) the percentage of polymer that persists in UV-irradiated thin films upon rinsing with chloroform. These polymers behave as negative-tone photoresists, enabling both direct photopatterning of conjugated polymers, and fabrication of multilayer conjugated polymer films by irradiating with UV light after each spin-casting step. Although hole-mobility values of these polymers in thin film transistors were only similar to 10(-5) cm(2) V-1 s(-1), photolysis and rinsing did not cause significant degradation in performance.

  Disclosed herein is a method of (and a sensor for) determining the presence of and/or concentration of superoxide anions in a sample of interest, the method comprising: • (a) providing an electrically conducting substrate having on a surface thereof a paste comprising an organic liquid binder and electrically conductive particles dispersed in the binder, contacting the paste with the sample of interest, wherein, if superoxide anions are present in the sample of interest, at least some of the superoxide anions are incorporated within the paste, wherein a first species is present within the paste at the time of contacting the paste with the sample of interest or a first species is incorporated into the paste after the contacting of the paste with the sample of interest, the superoxide anions then reacting with the first species to form a second species, • (b) using the electrically conducting substrate, having on a surface thereof the paste, produced in step (a) as a working electrode in an electrochemical test that involves altering the potential at a working electrode to a potential at which the first and/or second species is oxidised or reduced and obtaining electrochemical information, • (c) using the electrochemical information to determine the presence of and/or concentration of superoxide anions in the sample of interest.
