Using tetraethyl (5,5''-diiodo-[2,2':5',2''-terthiophene]-3',4'-diyl)bis(phosphonate), tetraethyl (5-(tributylstannyl)-[2,2'-bithiophene]-3,4-diyl)bis(phosphonate) to produce dodecaethyl [2,2':5',2'':5'',2''':5''',2'''':5'''',2''''':5''''',2''''''-septithiophene]-3',3''',3''''',4',4''',4'''''-hexaylhexakis(phosphonate), please predict the condition, including solvent and agent in SMILES notation in json format like:

```JSON
{
    "solvent": [
        "CCN(CC)CC",
        "CCOC(C)=O"
    ],
    "agent": [
        "On1nnc2ccccc21",
        "C(=NC1CCCCC1)=NC1CCCCC1",
        "Cl"
    ]
}
