Triphenylamine derivatives bridged by methylene units afford a near planar molecular platform In a series of one dimer and two oligomers exhibiting Increased structural rigidity compared to that of their parent triphenylamines. This series of dendrimers show significantly enhanced two-photon absorptions that are up to 3-fold that of triphenylamines with similar molecular size and structure.
