Supramolecular synthesis of novel organic and hybrid materials of pi-systems for optoelectronic functions

Abstract

The performance of organic electronic devices not only depends on the chemical structure of organic molecules but also on different hierarchies of their supramolecular organization. Thus, the self-assembly of π-conjugated systems has been a topic of immense interest for supramolecular chemists. In this context, self-assembly of wide variety of π- conjugated molecules have been investigated in detail to control their supramolecular organization. However, these self-assembled structures often showed poor device performance. The first half of this thesis presents our attempts to improve the optoelectronic functions of various self-assembled π-systems. We have mainly employed two strategies, namely, amphiphilic and charge-transfer (CT) approaches, towards this objective. In this section of introduction, we provide an overview on the design principles and optoelectronic functions of various self-assembled π-systems based on amphiphilic and charge-transfer (CT) approaches reported in literature.
