The major thrust of this proposal is the implementation of a small molecule approach as well as an oligomer approach towards self-ordering / self-assembling semiconducting nanocarbons (i.e., 1-dimensional carbon nanotubes and 2-dimensional graphene) to realize functioning charge transfer materials that unify light harvesting, charge separation, and catalysis. We propose in two different work packages several interlocking approaches involving design, materials, characterization, advanced measurements, and device fabrication. All of them are based on a broad range of spectroscopic and microscopic techniques and are meant to address a series of milestones that relate to tuning the electronic structure of functional nanocarbons by means of charge transfer / doping interactions. The self-ordering / self-assembling principles should be as simple as possible and, thus, several suitable functional building blocks will be utilized with a common denominator, namely photo- and redoxactivity. The composite nature of the resulting functional nanocarbons raises the exciting possibility of nanoscale charge transfer material having a tunable structure that can be tailored to a particular electronic functionality.

这一提议的主要目的是采用小分子方法以及低聚物方法来实现自排序/自组装半导体纳米碳(即一维碳纳米管和二维石墨烯)，以实现将光捕获、电荷分离和催化统一的功能电荷转移材料。我们在两个不同的工作包中提出了几种相互关联的方法，涉及设计、材料、表征、先进测量和器件制造。所有这些都基于广泛的光谱和显微技术，旨在解决与通过电荷转移/掺杂相互作用来调节功能纳米碳的电子结构有关的一系列里程碑。自排序/自组装原则应该尽可能简单，因此，几个合适的功能构建块将以一个共同的分母，即光和氧化还原活性来使用。由此产生的功能纳米碳的复合性质提高了纳米级电荷转移材料具有可调节结构的令人兴奋的可能性，该结构可以根据特定的电子功能进行定制。
