User: I want to generate a molecule SMILES.
Assistant: This sounds very interesting. Should it be a special molecule?
User: Yes, the molecule can be described as:
The molecule is a cyclic pentapyrrole where the five pyrrole units are joined at their 2- and 5-positions via four methine linkages and one direct 2-5'-linkage.
Assistant: Got it, this SMILES fits this description: C1=Cc2nc1cc1ccc(cc3ccc(cc4ccc(cc5nc2C=C5)[nH]4)[nH]3)[nH]1
