This award, made in the Special Projects Office of the Chemistry Division and the Polymers Program in the Division of Materials Research continues support for the research of Professors Reynolds and Katritzky at the University of Florida. The goal of the research is to design, synthesize and characterize electron-rich conducting polymers prepared from substituted condensed heterocycles including indolocarbazoles, bis(thieno)-benzenes, bis(pyrrolo)naphthalenes and bisindoles. These selected monomers lend themselves to facile electropolymerization. The planarity induced within the repeat unit and the low redox switching potentials will make the polymers quite stable when oxidatively doped and highly conducting. Pendant substituents will be incorporated onto the polymers to control polymer physical properties. Alkyl substitution will facilitate solubility and processibility. Polar substituents will be incorporated to enhance polymer interactions with electrolyte and ion-transport during redox switching. Alkyl sulfonate substitution will be used to induce water solubility and will lead to a new family of self-doped conducting polymers. Electropolymerized polymers formed on conducting surfaces can be easily switched between redox states resulting in highly controllable physical and electonic properties such as conductivity, ion content, volume and color. These materials are likely to find application in electrochromic devices, ion release electrodes, biosensors and transducers. The design, synthesis and characterization of new structures will advance the fundamental understanding of structure-property relationships in conducting polymers.

该奖项由化学部特别项目办公室和材料研究部聚合物项目颁发，继续支持佛罗里达大学雷诺兹和卡特里茨基教授的研究。该研究的目标是设计、合成和表征由取代稠合杂环（包括吲哚并咔唑、双（噻吩）苯、双（吡咯）萘和双吲哚）制备的富电子导电聚合物。这些选定的单体有助于容易的电聚合。 重复单元内诱导的平面性和低氧化还原转换电位将使聚合物在氧化掺杂和高导电性时相当稳定。侧链取代基将被结合到聚合物上以控制聚合物的物理性质。烷基取代将有利于溶解性和加工性。将加入极性取代基以增强聚合物与电解质的相互作用以及氧化还原切换过程中的离子传输。 烷基磺酸盐取代将用于诱导水溶性，并将产生一类新的自掺杂导电聚合物。 在导电表面上形成的电聚合聚合物可以在氧化还原态之间轻松切换，从而产生高度可控的物理和电子特性，例如电导率、离子含量、体积和颜色。这些材料可能在电致变色器件、离子释放电极、生物传感器和传感器中得到应用。新结构的设计、合成和表征将增进对导电聚合物结构-性能关系的基本理解。
