Claims
- 1. A chromophore having the following structural formula (I):
- 2. The chromophore of claim 1 wherein Ar1, Ar2 and Ar3 are single aromatic rings.
- 3. The chromophore of claim 2 wherein Ar1, Ar2 and Ar3 are benzene rings.
- 4. The chromophore of claim 1 wherein Ar2 includes a donor or acceptor group.
- 5. The chromophore of claim 1 wherein Ak1, Ak2, Ak3 and Ak4 are each (CH2)n, where n is from 1 to 10, and R1, R2 and R3 are each CH2)m—H, where m is from 1 to 10.
- 6. A distyrylbenzene chromophore having the following structural formula (II):
- 7. The chromophore of claim 6 in which the donor group is selected from the group consisting of I, Br, Cl, OC(O)R″, SH, OH, SR″, OR″, NHC(O)R″, NH2, NH″R, S−, and O−, where R″ refers to an alkyl group containing 1-50 carbon atoms.
- 8. The chromophore of claim 6 in which the acceptor group is selected from the group consisting of F, C(O)NR″2, C(O)NHR″, C(O)NH2, C(O)OR″, C(O)OH, C(O)R″, C(O)H, CN, S(O2)R″, and NO2, and where R″ refers to an alkyl group containing 1-50 carbon atoms.
- 9. The chromophore of claim 6 in which A1 and A2 are each hydrogen and n=1.
- 10. A distyrylbenzene chromophore having the following structural formula (III):
- 11. A distyrylbenzene chromophore having the following structural formula (IV):
- 12. A method of preparing a distyrylbenzene chromophore, comprising reacting a 1,4-dibenzylphosphonate with a haloalkylamino-benzaldehyde and adding a trialkylamine by condensation to said distyrylbenzene chromophore whereby to provide water solubility to said chromophore.
- 13. The method of claim 12 in which said haloalkylamino-benzaldehyde is a N,N-bis-(6-iodoalkyl)4-amino-benzaldehyde where the alkyl group has from 1 to 10 carbon atoms.
- 14. The method of claim 13 in which said N,N-bis-(6-iodohexyl)-4-amino-benzaldehyde is prepared by reacting N,N-bis-(6-hydroxyhexyl)-benzaldehyde with phosphorous oxychloride.
- 15. The method of claim 14 in which said N,N-bis-(6-hydroxyhexyl)-benzaldehyde is prepared by reacting aniline and 6-chloro-1-hexanol with a carbonate.
- 16. A method of preparing a water-soluble two-photon absorbing distyrylbenzene chromophore, comprising the following reaction:
