Stilbazolium derivative and nonlinear optical material using the same

摘要

Provided is a stilbazolium derivative represented by the general formula (I):;wherein R1, R2, R3, and R4 independently represent hydrogen, halogen, alkyl, hydroxyl, carboxyl, or amino; R5 represents hydrogen or alkyl; X represents oxygen or NR6 (R6 is hydrogen or alkyl); and Y− represents an anion. In the general formula (I), some or all of hydrogens maybe deuterium.

1. A stilbazolium derivative of formula (I): wherein R1, R2, R3, and R4 independently represent hydrogen, halogen, unsubstituted or substituted alkyl, hydroxyl, carboxyl, or amino; R5 represents hydrogen or unsubstituted or substituted alkyl; X represents oxygen or NR6 (R6 is hydrogen or unsubstituted or substituted alkyl); Y− represents an anion selected from the group consisting of sulfonic acid anions, carboxylic acid anions, hydrogen sulfate ions, nitrate ions, tetrafluoroborate ions, perchlorate ions, perbromate ions, and periodate ions; and in the general formula (I), some or all of hydrogens maybe deuterium wherein said substituted alkyl has a substituent selected from the group consisting of halogen, hydroxyl, ether, carboxyl, nitro, amino, and sulfone.
