Using 2',7'-dibromo-9,9-dihexyl-9H,9'H-[2,9'-bifluoren]-9'-ol, 9,9-dihexyl-9H-fluorene to produce 2',7'-dibromo-9,9,9'',9''-tetrahexyl-9H,9''H-2,9':9',2''-terfluorene, 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"
    ]
}
