Abstract: | In this paper, we have presented a range of new nitro-stilbene derivatives with benzophenones via ether or ester bridged bond.
These nitro-stilbene derivatives with benzophenones have been conveniently obtained by condensation reaction. The linked benzophenones
were efficiently introduced to nitro-stilbene dyes. The structures of these compounds have been characterized with NMR and
element analysis. The single crystals of two target compounds (11 and 12) have been obtained, and their X-ray crystallographic data have been determined and discussed. Remarkably different absorption
and fluorescence spectroscopy was observed for nitro-stilbene derivatives with benzophenones via different linked bonds. The
results show that electron-donating or electron withdrawing bridged bonds have significant influence on the absorption and
fluorescence spectroscopy, which makes it possible for the development of ideal nitro-stilbene dyes with benzophenones through
chemical strategy. |
