BENZALDEHYDE AMIDINOHYDRAZONE-7,7,8,8-TETRACYANOQUINODIMETHANE SALT AND ITS PRODUCTION

摘要

PURPOSE:To provide the title new compound useful as an organic semiconductor to be used in the electronic equipment or electronic material fields. CONSTITUTION:The objective compound, benzaldehyde amidinohydrazone-7,7,8,8- tetracyanoquinodimethane salt of formula I. The present compound can be obtained by reaction between (A) benzaldehyde amidinohydrazone hydrochloride of formula II and (B) lithium salt of 7,7,8,8-tetracyanoquinodimethane into benzaldehyde amidinohydrazone-7,7,8,8-tetracyanoquinodimethane salt (single salt) of formula III, which is, in turn, reacted with 7,7,8,8- tetracyanoquinodimethane.
