2-Thiopheneethylamine (2-(thiophen-2-yl)ethanamine) is an aromatic amine. It undergoes microwave induced condensation with iminodiacetic acid to form the corresponding piperazine-2,6-dione derivatives. Its effect as a probable substitute to the pyridine ligand on the performance of poly(3-hexylthiophene)/CdSe hybrid solar cells has been investigated.
