- SULFONIC ACID GROUP-CONTAINING DIAMINE COMPOUND AND METHOD FOR PRODUCING THE SAME
-
The present invention provides a novel sulfonic acid group-containing diamine compound represented by formula (1) below, and a method for producing the same. This compound has a fluorene skeleton with sulfonic acid groups or derivatives thereof. In this compound, a substituent having an amino group is bonded to each of carbon atoms at the 2-position and the 7-position in the skeleton, and no substituent is bonded to a carbon atom at the 9-position in the skeleton. A in formula (1) denotes an optionally-substituted divalent aliphatic group (having a carbon number of 10 or less) or an optionally-substituted divalent aromatic group (having the number of rings of 4 or less), for example.
