Effect of methylene spacers on the spectral, electrochemical, and structural properties of bis(4,4′-disubstituted-2,2′-bipyridyl) ruthenium(ii) dye analogues†
Abstract
Two new ruthenium complexes, [Ru(L1OMe)2(NCS)2] and [Ru(L2OMe)2(NCS)2] (where L1OMe = 2,2′-bipyridine-4,4′-di(methyl ethanoate) and L2OMe = 2,2′-bipyridine-4,4′-di(methyl propionate)), have been synthesized and characterized using spectroscopic and electrochemical techniques. The [Ru(L2OMe)2(NCS)2] complex has also been characterized by
