Here, we report a new class of organic sensitizers based on the bi-fluorenylidene moiety as π-linker within the donor–π-linker–acceptor (D–π–A) scheme. The new dyes are endowed with electron donor and electron acceptor units at strategic positions in order to improve their electronic and light-harvesting properties.The comprehensive study of these compounds through the use of different experimental and theoretical techniques, provides an in-depth 15 understanding of their electronic and photophysical properties, and reveal their interest as photovoltaic materials.engjournal articlehttp://pubs.rsc.org/en/content/articlelanding/tc/2016/c5tc03501e#!divAbstractopen access547Chemically modifiedHybrid photovoltaicsIn-depth understandingLight harvesting propertiesOptoelectronic propertiesPhotophysical propertiesPhotovoltaic materialsTheoretical techniqueQuímica orgánica (Química)2306 Química Orgánica
