Abstract
According to an embodiment, an electro-optic polymer comprises a host polymer and a guest nonlinear optical chromophore having the structure D-π-A, wherein: D is a donor, π is a π-bridge, and A is an acceptor; a bulky substituent group is covalently attached to at least one of D, π, or A; and the bulky substituent group has at least one non-covalent interaction with part of the host polymer that impedes chromophore depoling.
