Dicyanobenzothiadiazole Derivatives Possessing Switchable Dielectric Permittivities [PDF]

ACS Applied Materials & Interfaces, 2017
Benzothiadiazoles are important electron acceptors and are frequently employed as electron-deficient components of donor-acceptor polymers. We report the effect of nitrile functionalities on the reactivity, steric hindrance, optoelectronic properties, and dielectric permittivity in dicyanobenzothioadiazole (DCNBT).
