Metal-free synthesis of bisthiophene-core donor acceptor organic photosensitizers for dye-sensitized solar cells
摘要:
Three novel donor-it-acceptor molecules with a bis-thiophene core have been synthesized through a simple and versatile metal-free synthetic procedure. Study of their optical and electrochemical properties, and a preliminary evaluation of their use as dyes in dye sensitized solar cells (DSSC) are presented. The proposed synthetic protocol results in a drastic reduction of the size and complexity of the sensitizer molecule, possibly enabling cost decrease by overall yield improvement and easy scalability. Particular attention has been paid to limit the environmental impact by reducing the number of synthetic steps and especially avoiding the use of organometallic reactions. (C) 2015 Elsevier Ltd.

modifications suggested by the molecular modelling were verified by the synthesis of the designed molecules and by the evaluation of their in vitro activities against two lung tumour cell lines, A549 and H226. 2-(E)-2-[5′-(Dibutylamino)-2,2′-bithien-5-yl]vinyl}-1-methylquinoliniumiodide exhibited in vitro antiproliferative activity two orders of magnitude higher than that of the most active compound
