User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a member of the class of quinomethanes that is 3-methylidene-6-oxocyclohexa-1,4-diene-1-carboxylic acid in which the methylidene hydrogens are replaced by 4-carboxy-3-hydroxyphenyl groups. The trisodium salt is the biological stain 'chrome violet CG' while the triammonium salt is 'aluminon'. It has a role as a histological dye, an insulin-like growth factor receptor 1 antagonist and a fluorochrome. It is a monohydroxybenzoic acid, a member of quinomethanes and a tricarboxylic acid. It is a conjugate acid of an aurintricarboxylate.
Assistant: This is a molecule that fits this description: O=C(O)C1=CC(=C(c2ccc(O)c(C(=O)O)c2)c2ccc(O)c(C(=O)O)c2)C=CC1=O
