User: Can you generate the SMILES of a molecule based in this description:
The molecule is a cyclic tetrapyrrole anion that is the carbanion obtained by removal of the acidic proton from position 21 of pheophytin a. Major species at pH 7.3 It is a conjugate base of a pheophytin a.
Assistant: Of course, here you go: C=CC1=C(C)c2cc3[nH]c(c4c5[nH]c(cc6nc(cc1n2)C(C)=C6CC)c(C)c5C([O-])=C4C(=O)OC)[C@@H](CCC(=O)OC/C=C(\C)CCC[C@H](C)CCC[C@H](C)CCCC(C)C)[C@@H]3C
