Abstract
According to an embodiment, a nonlinear optical chromophore includes the structure D-π-A, wherein D is a donor, π is a π-bridge, and A is an acceptor, and wherein at least one of D, π, or A is covalently attached to a substituent group including a substituent center that is directly bonded to at least three aryl groups.
Claims25
A nonlinear optical chromophore comprising:
- the structure D-π-A;
- wherein D is a donor, π is a π-bridge, and A is an acceptor;
- and
- a substituent group covalently attached to at least one of D, π, or A, and including a substituent center atom directly bonded to at least three aryl groups.
A nonlinear optical chromophore, comprising:
- the structure D-π-A;
- wherein D is a donor, π is a π-bridge, and A is an acceptor, and
- wherein at least one of D, π, or A is covalently attached to a substituent group including the structure
- wherein X is C or Si;
- wherein Y3 is N or P;
- and
- wherein Ar1, Ar2, and Ar3 are aryl groups.
An electro-optic polymer including a nonlinear optical chromophore having the structure D-π-A, wherein D is a donor, π is a π-bridge, A is an acceptor, and at least one of D, π, or A is covalently attached to a substituent group including a substituent center that is directly bonded to at least one aryl group, and wherein the electro-optic polymer has greater temporal stability than when an alkyl group is substituted for the aryl group.
A method, comprising:
- a) providing a polymer including a nonlinear optical chromophore having the structure D-π-A;
