Abstract
Abstract Six multi-branched compounds (1–6) were conveniently synthesized through condensation reaction, and characterized by 1H NMR, 13C NMR, MS and single crystal X-ray diffraction. One-, two-photon absorption and emission properties were studied and theoretical calculations were applied to investigate the structure–property relationships, which showed that all the six compounds possessed good two photon absorption (2PA) properties. Their 2PA cross sections increased with the isophorone's branch number, the highest 2PA cross-section was 9398.23 GM for 6 in 1, 4-dioxane. Cytotoxicity tests indicated that all these compounds had good biocompatibility for living cells, bio-imaging studies highlighted the potential application of compounds 1, 2, 4 and 6 in both one- and two-photon fluorescence microscopy imaging domains.
