Abstract
Disclosed are organic electrooptic materials. The electrooptic materials are functionalized by novel methods and structures. The electrooptic materials are structured with a head and a tail where the head and tail sequentially assemble into a non-centrosymmetric ordered array. The electrooptic materials are further structured in covalently bonded dimer pairs where one of the pairs is zwitterionic. The non-centrosymmetric ordered array bonds directly to electrodes which allows for efficient application of the electric field. The organic electrooptic materials disclosed offer greater hyperpolarizability, greater bandwidth, reduced operating voltage with less optical loss.
