Optimizing the vectorial component of first hyperpolarizabilities of push–pull chromophores to boost the electro-optic activities of poled polymers over broad telecom wavelength bands

Abstract

Alternating the sequence of thiophene-based π-conjugation bridge of push–pull chromophores significantly improves the vectorial component of first hyperpolarizabilities and polar order of molecules for large electro-optic activities of poled films.
