Abstract: In this article the smart window application of a new type of thienylpyrrole derivative is presented. For this purpose, the new type of 2,5-di(2-thienyl)pyrrole derivative, which is named N-(2,5-di(thiophen-2-yl)-1H-pyrrol-1-yl)-4-(vinyloxy)benzamide (TPVB), has been prepared by the reaction of 1,4-di(2-thienyl)-1,4-butanedione and 4-(vinyloxy)benzohydrazide. Using hydrazine instead of amine in the synthesis process has significantly improved the related polymer's optical properties. Spectroelectrochemical investigations revealed that P(TPVB) is more durable with better long-term stability and has the lowest band gap compared with the other SNS derivatives. A chronoamperometry experiment showed that the P(TPVB) polymer film has excellent redox stability, moderate switching time and high optical contrast. So it is possible to use this polymer with superior optical properties in smart window applications. A smart window based on P(TPVB) and poly(3,4-ethylenedioxythiophene) (P(EDOT)) was set up in a sandwich configuration. Optoelectrochemical investigations displayed that the reduced state of the device displays an orange color whereas it is blue for the oxidized state. The switching time and optical contrast (?T%) of the device at 625 nm are 1.0 s and 43%, respectively.
