General description
Diphenylmethane is an aromatic compound used as a key building block in the synthesis of elastase inhibitors.
Application
- Diphenylmethane is widely used in the synthesis of luminogens for aggregation-induced emission (AIE).
- It is used in the preparation of a polymerization initiator, diphenylmethyl potassium (DPMK).
- It is one of the precursors in the synthesis of a dendrimeric polycyclic aromatic hydrocarbon (PAH), hexakis[4-(1,1,2-triphenyl-ethenyl)phenyl]benzene.
