<P>PROBLEM TO BE SOLVED: To provide a high-purity diacyl derivative of 1 ppm or less in chlorine ion content. <P>SOLUTION: The high-purity diacyl derivative consisting mainly of a diacyl derivative represented by general formula (1) and containing 1 ppm or less of chlorine ion is provided. In the general formula (1), A is a single bond, CH<SB POS="POST">2</SB>, SO<SB POS="POST">2</SB>, an oxygen atom, a sulfur atom, C(CH<SB POS="POST">3</SB>)<SB POS="POST">2</SB>, C(CF<SB POS="POST">3</SB>)<SB POS="POST">2</SB>or a residue of a fluorene structure; R<SB POS="POST">1</SB>and R<SB POS="POST">2</SB>are each a 1-3C monovalent organic group; R<SB POS="POST">3</SB>is H or methyl; Z is CH or a nitrogen atom; and m, n and p are each an integer of 0-2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
