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.
本发明提供了一种由下式(1)表示的新型含磺酸基的二胺化合物,以及生产该化合物的方法。这种化合物的芴骨架带有磺酸基团或其衍生物。在该化合物中,具有氨基的取代基分别键合在骨架中 2 位和 7 位的碳原子上,没有取代基键合在骨架中 9 位的碳原子上。例如,式(1)中的 A 表示任选取代的二价脂肪族基团(碳数为 10 或以下)或任选取代的二价芳香族基团(环数为 4 或以下)。
