The demands for alternative power sources have drawn attentions to a variety of light-harvesting devices. Among these, dye sensitized solar cells (DSSCs) have attracted a large number of research groups in two decades. In recent years, many numbers of chromophores with insulating alkyl chains, either on the bridge or the donor units, have been published. It has been shown that the efficiencies and stabilities of the sensitizers are strongly dependent on the position of these insulating alkyl chains. It is well-established that electron-donating groups at the para-position of the triphenylamine phenyls, e.g. alkoxy groups, red-shift the absorption spectrum and increase efficiency, where the degree of red-shift is dependent on the electron-donating strength of the substituent. We have designed and synthesized a sensitizer based on donor group using Fluorene moiety which 5,7-positions are substituted with hexyloxy chains. This dye can be used to study the impact of structural modification on the optical and electrochemical properties.
