User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an arenesulfonic acid, the disodium salt of which is the histological dye 'methyl blue' (used for staining collagen in Masson's trichrome and Mallory's method for connective tissue). It is an arenesulfonic acid, an imine, an aromatic amine and a secondary amino compound. It is a conjugate acid of a methyl blue(2-).
Assistant: This is a molecule that fits this description: O=S(=O)(O)c1ccc(N=C2C=CC(=C(c3ccc(Nc4ccc(S(=O)(=O)O)cc4)cc3)c3ccc(Nc4ccc(S(=O)(=O)O)cc4)cc3)C=C2)cc1
