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.

该提案的主要目的是实施一种小分子方法以及用于自我排序 /自组装的半导体纳米碳（即1维碳纳米管和2二维石墨烯）的低聚方法，以实现实现功能传递的电荷传递材料，以统一光收获光收获，电荷分离，猫分离和猫分离和猫分离。 我们在两个不同的工作包中提出了涉及设计，材料，表征，高级测量和设备制造的几种互锁方法。 所有这些都基于广泛的光谱和微观技术，旨在解决与通过电荷传递 /掺杂相互作用来调整功能性纳米碳的电子结构有关的一系列里程碑。 自我排序 /自组装原理应尽可能简单，因此，将使用一个共同的分母（即照片和氧化还原性）使用几个合适的功能构建块。 所得功能性纳米碳的复合性质提高了具有可调结构的纳米级电荷转移材料的令人兴奋的可能性，可以根据特定的电子功能量身定制可调结构。
