In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, Kirk S. Schanze of the University of Florida will investigate fundamental properties of carrier transport in conducting polymer molecular wires and thin films. The overall objective of the program is to provide a clear understanding of the structure, energetics and dynamics of triplet exciton states in pi-conjugated, weakly conjugated and non-conjugated model molecular and polymeric chromophore assembliles. The structures that will be the focus of study feature platinum metal units as a primary element. These metal centers serve to enhance triplet spin state generation in the materials and promote room temperature phosphorescence. Understanding the properties of photoexcited states in molecules and polymers with delocalized electronic systems is very important because these materials are receiving a great deal of attention from scientists and engineers for application in a new generation of plastic electronic devices. In particular, the questions addressed in this research program are broadly relevant to applications of organic and organometallic materials in high efficiency light sources (organic light emitting diodes), organic solar cells (light driven electrical power generation), and in control and attenuation of laser light (non-linear optical materials). This research program provides also serves as key training for postdoc, graduate and undergraduate students in the principal investigator's laboratory. These students obtain broad training in skills ranging from synthetic chemistry to the application of physical methods such as optical spectroscopy and materials characterization. In addition, as part of this project the research group will participate in the Student Science Training Program (SSTP) with a seven-week residential program held each summer at the University of Florida for high school students (11th and 12th graders) interested in careers in science, math and engineering. Each summer the Schanze group will host an SSTP student, getting them involved in the research project, as well as interacting with the full group of SSTP students in seminar and workshop settings.

在由化学部的大分子，超分子和纳米化学计划资助的项目中，佛罗里达大学的Kirk S. Schanze将研究载体运输的基本特性在导电聚合物分子线和薄膜中。 该程序的总体目的是清楚地了解PI共轭，弱共轭和非偶联的模型分子和聚合物生色素组合物中三重态激子状态的结构，能量和动力学。 研究重点的结构以铂金属单元作为主要元素。这些金属中心有助于增强材料中的三重态自旋态生成并促进室温磷光。 了解具有离域电子系统的光激发状态在分子和聚合物中的特性非常重要，因为这些材料正在从科学家和工程师那里受到广泛关注，以在新一代的塑料电子设备中应用。特别是，本研究计划中提出的问题与有机和有机金属材料在高效率光源（有机光发射二极管），有机太阳能电池（光驱动电力发电）以及激光（非线性光学材料）的控制和衰减中的应用大致相关。 该研究计划还提供了主要研究人员实验室的博士后，研究生和本科生的关键培训。 这些学生获得了从合成化学到应用物理方法（例如光谱和材料表征）的应用的广泛培训。 此外，作为该项目的一部分，研究小组将参加学生科学培训计划（SSTP），每年夏天在佛罗里达大学为高中生（11年级和12年级）举办的为期7周的住宅计划（11年级和12年级），对科学，数学和工程学的职业感兴趣。 每年夏天，Schanze Group都会接待SSTP学生，让他们参与研究项目，并与整个SSTP学生在研讨会和研讨会环境中进行互动。
