Abstract

Provided is a stilbazolium derivative represented by the general formula (I):

wherein R 1 , R 2 , R 3 , and R 4 independently represent hydrogen, halogen, alkyl, hydroxyl, carboxyl, or amino; R 5 represents hydrogen or alkyl; X represents oxygen or NR 6 (R 6 is hydrogen or alkyl); and Y − represents an anion. In the general formula (I), some or all of hydrogens maybe deuterium.
