TL;DR: In this paper, the authors evaluated donorπ-linker acceptor (D-π-A) dyes experimentally, which either have 1 or 3 triphenylamine (TPA) donor in combination with either pyridine or N -methyl pyridinium ion ion as acceptor.

TL;DR: Two photon absorption (2PA) cross sections of two quasi-octupolar molecules (E, E, E )-2,4,6-tris [2-(4- N, N -diphenylaminophenyl)vinyl]pyridine (DPATSP) and (2, 4, 6-trithm((E )-4-(diphenyl)styryl)-1-methylpyridinium-1-ium iodide, DPATSP-Me) have been estimated as discussed by the authors.
Abstract: Two photon absorption (2PA) cross sections of two quasi-octupolar molecules ( E , E , E )-2,4,6-tris [2-(4- N , N -diphenylaminophenyl)vinyl]pyridine (DPATSP) and (2,4,6-tris(( E )-4-(diphenylamino)styryl)-1-methylpyridine-1-ium iodide, DPATSP-Me) have been estimated. It has been found that by introducing the pyridinium ion, the 2PA cross section of DPATSP-Me increases with respect to the parent molecule, DPATSP. Z-scan experiments on the two samples reveal that DPATSP-Me is a better candidate for optical limiting applications.

Abstract: Towards the synthesis of symmetrical and unsymmetrical β,β-diarylacroleins for assembling diarylmethine fragments present in biologically important molecules, we have developed a new Weinreb amide (WA) based building block, derived from propiolic acid. The WA functionality present in this compound allowed the sequential addition of various arylmagnesium bromide reagents in a controlled manner. The developed methodology for the access to β,β-diarylacroleins has been utilised for the synthesis of biologically important 3-arylindanone molecules.
