文摘

Two novel D-π-D type triphenylamine chromophores with long π-conjugated bridge and strong electron-donating moiety were reported. The centrosymmetric structures were determined by single crystal X-ray diffraction analysis. Two chromophores both exhibited intense and wide-dispersed one-photon/two-photon excited fluorescence, bear prodigious 2PA cross section (δ). Dye2 could effectively uptake toward living cells and display a uniformly localized in cytosolic space.
