User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an organosulfonate oxoanion obtained by deprotonation of the four sulfo groups of 6,6'-{(3,3'-dimethyl[1,1'-biphenyl]-4,4'-diyl)bis[diazene-2,1-diyl]}bis(4-amino-5-hydroxynaphthalene-1,3-disulfonic acid). It is a conjugate base of an Evans blue free acid.
Assistant: This is a molecule that fits this description: Cc1cc(-c2ccc(N=Nc3ccc4c(S(=O)(=O)[O-])cc(S(=O)(=O)[O-])c(N)c4c3O)c(C)c2)ccc1N=Nc1ccc2c(S(=O)(=O)[O-])cc(S(=O)(=O)[O-])c(N)c2c1O
