Abstract

We present here a convenient synthesis of the landmark dye-sensitized solar cell dye [Bu₄N]₂[Ru(4-carboxy-4-carboxylate-2,2′-bipyridine)₂(NCS)₂] (N719). Key to this synthetic procedure is the protection of the carboxyl functionalities with iso-butyl ester groups. This strategy allows the use of silica chromatography to remove the less efficient S-bound isomers and significantly reduces the time and difficulty of the synthesis.
