Development of Versatile Building Blocks for Stepwise Synthesis of Multi-function Integrated Macromolecules

Abstract

We have been developing step-wise synthetic protocols for mono-molecular integration technology, which integrates the quantum dots, tunnel junctions, and the required passive elements of quantum device on a single macromolecule. In this line, we devised a library of versatile building blocks. The functionality of these blocks is based on the chemical reactivity of 3,4-diaminothiophene component, which can be easily modified to tune the structural and electronic properties of the main p-conjugated chain. It is facile to access to various series of p-conjugated macromolecules using Pd-catalyzed cross-coupling or Ni-induced biaryl coupling reactions of these building blocks. Some typical examples of our step-wise bottom-up architecture will be demonstrated in the presentation.
