Efficient Light Harvesters Based on the 10-(1,3-Dithiol-2-ylidene)anthracene Core


Solar energy represents nowadays one of the most realistic alternatives to the use of fossil fuels. Photovoltaic devices based on organic compounds (OPV) have experienced a tremendous development in the last years, 1 and recently efficiencies around 8-10% have been 1 (a) Thompson, B.

Rev. 2012, 41, 4245-4272. reported. 2 One of the crucial points to understand this improvement is the careful election of suitable organic materials able to fulfill some energetic and electronic requirements. Among these requisites, the ability of the material to harvest sunlight in a broad range of the visible and NIR spectrum is decisive in order to obtain a suitable photoresponse. In this regard, organic chromophores such as push-pull systems, displaying outstanding absorption 2 (a) Huo, L.; Zhang, S.; Guo, X.; Xu, F.; Li, Y.; Hou, J. Angew. Three new push-pull chromophores based on the 10-(1,3-dithiol-2-ylidene)anthracene core were synthesized and fully characterized. The new chromophores display broad absorption spectra, nearly covering the whole visible region, with high extinction coefficients. Electrochemistry and theoretical calculations allowed the understanding of these singular electronic properties. The molecular structures were unambiguously confirmed by X-ray diffraction. Slow evap
