2,6-Bis(trimethyltin)-4,8-bis(2-ethylhexyloxy)benzo[1,2-b:4,5-b′]dithiophene,the monomer of a polymer solar cells material,was synthesized from 4,8-dihydrobenzo[1,2-b:4,5-b′]dithiophen-4,8-dione.The structure of the compound was determined by multinuclear NMR spectroscopy,including 1H,13C,119Sn,117Sn NMR,DEPT,selective 1D TOCSY and 2D NMR techniques including 1H-1H COSY,gHSQC and gHMBC.The 1H,13C,119Sn,117Sn NMR chemical shifts were assigned and the spectral features of the compound were discussed.
