The ability to control self-assembly in nano-structured materials plays a prevalent role towards the development of highly optimal electronic devices.  As such, the self-assembled components can strongly affect the internal processes associated with energy transfer and conversion in semiconductor devices.   In addressing this issue, directed self-assembly can provide a route to well-organized structures with high molecular level precision and minimal structural defects that have been proven detrimental to organic electronic applications.  Controlling the supramolecular self-assembly via molecular composition and functionality offers a unique strategy to provide targeted functional patterns in a reproducibly controlled fashion. As such, the incorporation of other polymers or end groups via copolymerization and/or organic syntheses to induce various idealized morphologies towards the design of efficient and high-performance electronic devices will be investigated.  Herein, I demonstrate the use of copolymerization and end group functionalization procedures to influence the intrinsic properties poly-3-alkylthiophenes. P3HT block copolymers consisting of various units will be discussed in terms of their structure-property relationships with distinct focus on the influence on self-assembly and electronic properties of P3HTs.
