  Synthesis and photophysical properties of two novel branched pyridinium inner salt dyes

  摘要：

  Two new branched pyridinium inner salt dyes, 2,6-di[2-(N-ethyl-carbazole-3-yl)vinyl]-N-(3-sulfonate-propyl)pyridinium, inner salt (2) and 2,4,6-tri[2-(N-ethyl-carbazole-3-yl)vinyl]-N-(3-sulfonatepropyl) pyridinium, inner salt (3), with N-ethyl-carbazolyl as electron donor group and pyridine cation as electron acceptor group have been synthesized. Their single- and two-photon related fluorescence properties in various solvents have also been examined. These dyes exhibit stronger fluorescence emission relative to the corresponding linear counterpart and common pyridinium dyes with discrete cation and anion components. Three-branched organic dye 3 has a high fluorescence quantum yield as 0.12 and exhibits strong orange two-photon excited fluorescence at 608 nm in THF with large two-photon absorption cross-section being 606 GM.
