Abstract:
A highly efficient fluorescent probe, thiosemicarbazone-triphenylacetylene (1) has
been designed and synthesized containing triphenylacetylene as fluorophore and
thiosemicarbazone as Hg2+ and Cu2+ probe via sonograsira coupling and Knoevenagel
condensation reaction in 3 step with good % yield of confirmed by using 1H, 13C NMR, IR,
HRMS. The photophysical properties of fluorophore, the maximum absorbance wavelength
(λabs) was 385 nm and the maximum fluorescent emission wavelength (λem) was 490 nm in
propylene glycol 40 % (v/v) mixed 10 mM PBS buffer pH 7.4. Additionally, the potential
application of thiosemicarbazone-triphenylacetylene fluorophore exhibited highly selective
detection of Hg2+ and Cu2+ ions based fluorescent turn-off mode. We also investigated the
fluorogenic behaviors of 1 in the presence of metal ions such as Na+, K+, Mg2+, Ca2+, Mn2+,
Fe2+, Co2+, Ni2+, Ag+, Zn2+, Al3+, Sn2+ and Pb2+. The fluorescence signal of 1 can be
quenched by Hg2+ and Cu2+ ions, whereas there are no significant effects on the other 13
cation ions
