Abstract
The present invention is directed, in general, to nonlinear optical chromophores having a Michler's base-type group. Various embodiments of the present invention include nonlinear optical chromophores with Michler's base-type group having a Michler's base donor group connected to a Π-bridge group. Various embodiments of the present invention include nonlinear optical chromophores with Michler's base-type group having high photostability, which chromophores can reduce the percentage of being deactivated by molecular oxygen under illumination.
Claims10
A nonlinear optical chromophore of the general formula (I):
- D-Π-A (I)
- wherein D represents an organic electron-donating group;
- A represents an organic electron-accepting group;
- and Π represents a Π-bridge between A and D, wherein the Π-bridge comprises a carbon chain covalently bound to and separating A and D;
- wherein D comprises one Michler's base-type donor group, wherein the Michler's base-type donor group comprises a symmetric Michler's base-type donor, wherein the Michler's base-type donor group represents the symmetric Michler's base-type donor of the general formula (Da):
- wherein R1 and R2 each independently represents a moiety selected from the group consisting of H, unsubstituted C3-C10 alkyl, substituted C1-C10 alkyl, substituted or unsubstituted C2-C10 alkenyl, substituted or unsubstituted C2-C10 alkynyl, substituted or unsubstituted aryl, substituted or unsubstituted alkylaryl, substituted or unsubstituted carbocyclic, substituted or unsubstituted heterocyclic, substituted or unsubstituted cyclohexyl, and (CH2)n—O—(CH2)n where n is 1-10.
