| Abstract: | A new organic dye(named L1)containing butoxy group as donor was designed and synthesized. Treatment of 4-bromophenol with n-BuI and B(OCH_3)_3 gave the boronic acid.The intermediate aldehyde was prepared from bis-thiophene via bromonation reaction with N-bromosuccinimide(NBS)and Vilsmeier -Haack reaction.The dye was synthesized from the Suzuki coupling reaction of the boronic acid with the aldehyde,followed by Knoevenagel condensation reaction with cyanoacetic acid.The dye was applied to nanocrystalline TiO... |
