Thermally stable poled polyquinoline thin film with very large electro-optic response

Abstract

Poled guest-host polyquinoline thin films are shown to demonstrate both exceptionally large electro-optic activity and long-term stability. After an initial drop from 45 to 26 pm/V in the first 100 h, the electro-optic coefficient r33 at 26 pm/V remained for more than 2000 h.
