User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an N-hydroxysuccinimide ester derived from 6-carboxyfluorescein. A fluorescent cell staining dye, it is cell permeable and covalently couples, via its succinimidyl group, to intracellular molecules, notably to intracellular lysine residues. It has a role as a fluorochrome. It derives from a fluorescein.
Assistant: This is a molecule that fits this description: O=C(ON1C(=O)CCC1=O)c1ccc2c(c1)C1(OC2=O)c2ccc(O)cc2Oc2cc(O)ccc21
