The Uses of 3-Thiopheneacetic acid
3-Thiopheneacetic acid was used in:
- one-step, size control synthesis of gold nanoparticles
- in the preparation of gold nanoparticles capped with 3-thiopheneacetic acid (3-TAA) via borohydride reduction
The Uses of 3-Thiopheneacetic acid
3-Thiopheneacetic acid was used in one-step, size control synthesis of gold nanoparticles. It was also used in the preparation of gold nanoparticles capped with 3-thiopheneacetic acid (3-TAA) via borohydride reduction.
General Description
3-Thiopheneacetic acid acts as monocarboxylate ligand and forms oxo-carboxylate bridged digadolinium(III) complexes. Electrochemical oxidation of 3-thiopheneacetic acid in dry acetonitrile leads to the formation of a conducting polymeric film of poly (3-thiopheneacetic acid).
Purification Methods
Crystallise the acid from ligroin or H2O. [Beilstein 18 III/IV 4066.]
