Organic compound and electrochromic element including the same

An organic compound represented by Formula [1]:

• wherein, A1 to A6 each independently represent a substituent selected from a hydrogen atom, alkyl groups having 1 to 20 carbon atoms, alkoxy groups having 1 to 20 carbon atoms, and optionally substituted aryl groups, wherein a substituent of the optionally substituted aryl group is selected from halogen atoms, alkyl groups having 1 to 4 carbon atoms, alkoxy groups having 1 to 4 carbon atoms, aryl groups, aralkyl groups, substituted amino groups, and substituted silyl groups;
• n is an integer of 1 to 4;
• B's each independently represent a hydrogen atom or a substituent represented by Formula [2], provided that at least one of four B's represents a substituent represented by Formula [2]:
• wherein X− represents an anion, and R2 represents an optionally substituted alkyl group having 1 to 20 carbon atoms or an optionally substituted aryl group;
• Y represents a structure represented by any one of Formulae [3] to [6], provided that when n represents a number of 2 or more, Y's are each independently selected from Formulae [3] to [6]:
• wherein R3 represents an alkylene group having 1 to 20 carbon atoms, and R4 to R9 are each independently selected from a hydrogen atom, halogen atoms, alkyl groups having 1 to 20 carbon atoms, alkoxy groups having 1 to 20 carbon atoms, optionally substituted aryl groups, alkyl ester groups having 1 to 20 carbon atoms, optionally substituted amino groups, and a cyano group.
