Orthogonally Functionalized Naphthodithiophenes: Selective Protection and Borylation
摘要:
Selective functionalization protocols of naphtho[1,2-b;5,6-b']dithiophene (NDT3) by combining protection of the thiophene alpha-positions and direct borylation on the naphthalene core are described, which allows synthesizing a number of new NDT3-based building blocks with various substituents and isomeric NDT3-based polymers with different main chain structures. The same protocol is applicable to other isomeric naphthodithiophenes (NDTs), which affords a set of key building blocks for the development of elaborated functional pi-materials.

set of three donor‐acceptor conjugated (D‐A) copolymers were designed and synthesized via Stille cross‐coupling reactions with the aim of modulating the optical and electronicproperties of a newly emerged naphtho[1,2‐b:5,6‐b′]dithiophenedonorunit for polymer solar cell (PSCs) applications. The PTNDTT‐BT, PTNDTT‐BTz, and PTNDTT‐DPP polymers incorporated naphtho[1,2‐b:5,6‐b′]dithiophene (NDT) as the
