Porres, Laurent published the artcileEnhanced two-photon absorption with novel octupolar propeller-shaped fluorophores derived from triphenylamine, HPLC of Formula: 21101-63-3, the publication is Organic Letters (2004), 6(1), 47-50, database is CAplus and MEDLINE.
Novel octupolar fluorophores derived from the sym. functionalization of a triphenylamine core with strong acceptor peripheral groups via phenylene-ethynylene linkers have been synthesized and shown to exhibit high fluorescence quantum yields, very large two-photon-absorption cross-sections in the red-NIR region, and suitable photostability.
