Bis-1,4-(<i>p</i>-diarylaminostryl)-2,5-dicyanobenzene Derivatives with Large Two-Photon Absorption Cross-Sections

Abstract

Synthesis and physical properties of novel multibranched two-photon materials are reported. The compound with three units of 4-(p-diphenylaminostyryl)-2,5-dicyanostyryl moieties attached to the central triphenylamine core exhibits a very large two-photon absorption cross-section.
