Document Type and Number:
WIPO Patent Application WO/2012/132269
Kind Code:
A1
Abstract:
The present invention provides a novel diamine compound that contains a sulfonic acid group and is represented by formula (1), and a method for producing the same. This compound has a fluorene backbone including a sulfonic acid group or a derivative thereof. In this compound, a substituent having an amino group is bonded to the 2- or 7-position carbon atom in the backbone, and no substituent is bonded to the 9-position carbon atom in the backbone. In formula (1), A represents, for example, an optionally substituted divalent aliphatic group (C10 or less) and an aromatic group (number of rings being four or less).
