Facile synthesis of urea containing thiophene monomer and its application in the field of D-A conjugated polymer
Keywords:Conjugation Break Spacer, Monomer, D-A conjugated polymers, H-bonding, Urea polymer, urea-thiophene conjugate
Conjugation Break Spacer “CBS” methodology has proved to be an efficient tool to introduce the flexibility and stretchability into the otherwise known rigid polymeric backbone. CBS monomers with H-bonding unit are widely used in conjugated polymer to make electronic device intrinsically stretchable and self-healable. However, dealing with strong h-bonding system like urea, it always associate with an uphill task of purification of monomer in each step. Here, we report an efficient method of purification of urea based thiophene monomer in both of its synthetic steps into a single crystal and its application as CBS in the i-indigo D-A conjugated polymer.
