Abstract
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.
