Photoactive rosette nanotubes

Abstract

Generation of well-ordered organic photoactive moieties through self-assembled/self-organized systems to improve the electronic and optical properties of materials is an ongoing challenge in supramolecular engineering and material science. Nanowires and nanotubes are one of the most extensively studied supramolecular structures in electronic and photonic applications. Even though self-assembly of various moieties into the desired nanotubes or nanowires can be achieved, controlling uniform size distribution and preventing agglomeration remains a challenge. These non-uniformity and aggregation problems have imposed a challenge of luminescence loss (quenching), which in turn limits incorporation of the systems into devices. This problem imposed performance difference between the individual building units and ensembles. Thus, nanowires or nanotubes, which are operationally simple to prepare, and have built-in optical and electronic properties, are of great interest. This thesis approaches the aforementioned challenges in a different and elegant way by designing photoactive rosette nanotubes.
