Triphenylamine-thiophene organic dyestuff as well as preparation method and application thereof

The invention provides a triphenylamine-thiophene organic dyestuff. The structural general formula of the triphenylamine-thiophene organic dyestuff is as shown in a formula (I), wherein in the formula (I), R1 is C1-C6 alkoxy, the structural formula of Ar is as shown in a formula (II) or a formula (III), and R2 in the formulas (II) and (III) is C1-C6 alkyls. A preparation method of the triphenylamine-thiophene organic dyestuff comprises the following steps: sequentially carrying out Suzuki coupled reaction and Knoevenagel condensation reaction by using aryl bromal, tetrakis(triphenylphosphine)palladium(0), potassium carbonate and alkoxy substituted triphenylamine boron ester as raw materials, thus obtaining a target product. The triphenylamine-thiophene organic dyestuff can serve as a photosensitizer of a dye-sensitized solar cell. The triphenylamine-thiophene organic dyestuff has the advantages that the distortion spatial structure of alkyl triphenylamine is capable of effectively suppressing the electron recombination and increasing the open-circuit voltage; a thiophene derivative serving as a dyestuff molecule conjugated bridge is capable of ensuring the high molar absorption coefficient and has relatively strong power supply performance, so that the ideal photoelectric conversion efficiency is ensured.
