Answer
![N,N,N',N',N'',N'',N''',N'''-Octakis(4-methoxyphenyl)-9,9'-spirobi[fluorene]-2,2',7,7'-tetramine](https://static.chemtradehub.com/structs/207/207739-72-8-f8d3.webp "N,N,N',N',N'',N'',N''',N'''-Octakis(4-methoxyphenyl)-9,9'-spirobi[fluorene]-2,2',7,7'-tetramine")
The compound is synthesized through the condensation reaction of 4-methoxyphenyl isocyanates with 9,9'-spirobi[fluorene]-2,7-dione. The synthesis involves multiple steps and typically requires catalysts such as 4-(N,N-dimethylamino)pyridine (DMAP) and triethylamine (TEA) to enhance the efficiency. The overall yield is moderate, and the process requires careful control of reaction conditions to achieve high purity.
