Synthesis and Self-Assembly of Conjugated Block Copolymers

Abstract: 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 h… Show more

“…Poly(4-vinylpyridine) (PVP) is a linear polymer with pendant pyridine groups that can be used in a variety of applications, such as surface modification, by immobilizing atoms or particles, electrochemical sensors [ 20 ], fabrication of antibacterial surfaces, development of pH sensitive systems, 3D molecular level ordering systems, anti-corrosive coatings and even dye sensitized solar cells (DSSCs) and light-emitting diodes [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. Positively charged polypyridines constitute a unique class of compounds in which quaternization enables the introduction of permanent positive charges into the backbone, resulting in electron delocalization phenomena that are attributed to the existence of electron-rich pyridines and electron-poor pyridiniums [ 30 , 31 , 32 , 33 ].…”

“…Despite their outstanding performance in optoelectronic applications, CPs nonetheless are limited by several challenges . While approaches have recently been developed to overcome some of these challenges, notably CPs still lack effective synthetic methods to make narrow dispersity and high molecular weight polymers, which are crucial for the fabrication of efficient optoelectronic devices and the development of advanced architectures such as block copolymers. , Poor environmental stability and restricted mechanical properties are also limitations of CPs. , …”

“…For the rod−coil block copolymers, however, because of the strong π−π interchain interaction as well as the more stretched, rigid chains of conjugated polymers that tend to firmly pack into crystalline nanofibrils, the microphase separated structure is dominated by rod blocks. 40,41 Despite this, the microstructures of rod−coil block copolymer thin films can still be fine-tuned to optimize their morphologies and corresponding mechanical and electrical properties by applying various combinations of rod and coil blocks. 42 Recently, several published reports have applied poly(3hexylthiophene) (P3HT)-based rod−coil block copolymers to the fabrication of stretchable organic transistors.…”
