TL;DR: The syntheses and comprehensive characterization of 14 organic semiconductors based on perylene bisimide (PBI) dyes that are equipped with up to four halogen substituent in the bay area of the perylene core and five different highly fluorinated imide substituents are described, making them suitable for a wide range of practical applications.

TL;DR: D–A dyes with flat structures that undoubtedly form centrosymmetric dimers with perfectly cancelled dipole moments in the solid state are introduced, clearly placing D– A dyes now among the top-performing small molecules in the field of organic photovoltaics.

TL;DR: Traditional low-molecular weight colorants that are widely applied in textile coloration, for printing purposes and nonlinear optics, now afford bulk heterojunction solar cells in combination with soluble C(60) fullerene derivative PCBM with power conversion efficiencies up to 1.7% under standard solar radiation.

TL;DR: In this article, a solution-processed bulk-heterojunction solar cells based on the merocyanine dye MD304 as a donor in combination with the soluble fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) as acceptor are presented.

TL;DR: In this paper, a newly synthesized series of bis(merocyanine) dyes bearing alkyl substituents of different chain lengths and branching further reveals that small structural changes of the monomeric building blocks have a considerable impact on the stability and structure of the aggregates.
