Task: Please give me a SMILES based on the text description below.
Description: The molecule is a nitroarene that is pyrene substituted at the 1-position by a nitro group. A by-product of combustion, it is the predominant nitrated polycyclic aromatic hydrocarbon emitted in a diesel engine. It has a role as a carcinogenic agent. It derives from a hydride of a pyrene.
Result: O=[N+]([O-])c1ccc2ccc3cccc4ccc1c2c34
