Bis-1,4(p-diarylaminostryl)-2,5-dicyanobenzene derivatives with large two-photon absorption cross-sections

[GRAPHICS] 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 absorpt ion cross-section.
