Bridged triphenylamine-based dendrimers: tuning enhanced two-photon absorption performance with locked molecular planarity

Org Lett. 2009 Jan 1;11(1):1-4. doi: 10.1021/ol801238n.

Abstract

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.
