Аннотация:A new star-shaped D-[small pi]-A small molecule, 2,2[prime or minute],2[prime or minute][prime or minute]-nitrilotris[(3-methoxy-4,1-phenylene)-2,2[prime or minute]-bithiene-5[prime or minute],5-diyleth-1-yl-1-ylidene]trimalononitrile N(Ph(OMe)-2T-DCN-Me)3, with high efficiency potential for photovoltaic applications was synthesized. Introducing a soluble tris(2-methoxyphenyl)amine (TPA-MeO) core unit can significantly improve the solubility of star-shaped small molecules without negatively impacting intramolecular conjugation and intermolecular solid state arrangements. Solution-processed organic solar cells based on a blend of N(Ph(OMe)-2T-DCN-Me)3 and PC70BM show an initially high power conversion efficiency of over 4% under simulated AM 1.5.
