Functional Nanoparticles-driven Self-assembled Diblock Copolymer Hybrid Nano-Patterns

Herein, we report how functional gold nanoparticles can drive the block copolymer BCP thin film morphologies of polystyrene-block-poly(vinylbenzyl-3-(2-(2-(2-methoxyethoxy)ethoxy)ethoxy)prop-1-yne (PS-b-PVBEG). PS-b-PVBEG was obtained via Nitroxide Mediated Polymerization and two consecutive post-polymerization...

Synthesis and Self-Assembly of Conjugated Block Copolymers

In the past two decades, conjugated polymers (CPs) have drawn great attention due to their excellent conductivity and charge mobility, rendering them broad applications in organic electronics. Controlling over the morphologies and nanostructures of CPs is very important to improve the performance of CP-based devices, which is still a tremendously difficult task. Conjugated block copolymers (cBCPs), composed of different CP blocks or CP coupled with coiled polymeric blocks, not only maintain the advantages of high conductivity and mobility but also demonstrate features of morphological versatility and tunability. Due to the strong π-π interaction and crystallinity of the conjugated backbones, the self-assembly behaviors of cBCPs are very complicated and largely remain to be explored. In this tutorial review, we first summarize the general synthetic methods for different types of cBCPs. Then, recent studies on the self-assembly behaviors of cBCPs are discussed, with an emphasis on the structural factors that affect the morphologies of cBCPs both in bulk and thin film states. Finally, we briefly provide our outlook on the future research of the self-assembly of cBCPs.
