dimerize into tetrathiafulvalene vinylogues (TTFVs). These systems, in turn, exhibit a reversible redox-driven conformational switching between a charge neutral cisoid and a dicationic transoid form. Both types of dyes have already been utilized, as organic sensitizers, in dye-sensitized solar cells (DSSCs). A series of DTF- and TTFV-bearing Ru(II) bis-terpyridyl complexes has been prepared and characterized

染料已被用作
染料敏化太阳能电池(DSSC)中的有机敏化剂。已经制备了一系列带有DTF和
