Crosslinked compositions comprising a poly(arylene ether) and a nonlinear optical chromophore, and devices incorporating same

An electro-optic device comprising a composition made by a process comprising:

• a) providing precursor composition comprising a nonlinear optical chromophore having the structure D-π-A and a polymer comprising units having the formula
• and b) crosslinking the polymer, wherein:
• D is a donor;
• π is a π-bridge;
• A is an acceptor;
• Q1 comprises at least one aryl or heteroaryl group;
• Q2 comprises at least one aryl or heteroaryl group;
• X1 is O bonded directly to an aryl carbon of Q1;
• X2 is O bonded directly to an aryl carbon of Q2;
• Z is a linker comprising at least one —(C(R2)2)— group;
• Y is a single bond or a linker group;
• R1 is independently at each occurrence H, a halogen, an alkyl group, a heteroalkyl group, an aryl group, or a heteroaryl group;
• R2 is independently at each occurrence H, an alkyl group, or a heteroalkyl group;
• and
• R3 is H or a crosslinkable group.
