  Tri-Diketopyrrolopyrrole Molecular Donor Materials for High-Performance Solution-Processed Bulk Heterojunction Solar Cells

  摘要：

  Two new high-performance DPP-containing donor molecules employing a molecular architecture with three DPP chromorphores (tri-DPP) in conjugated backbones are synthesized and characterized. The two tri-DPP molecules with only a structural difference on alkyl substitutions, when blended with PC71 BM, lead to power conversion efficiencies up to 4.8 and 5.5%, respectively.

  Red Emitting N-Functionalized Poly(1,4-diketo-3,6-diphenylpyrrolo[3,4-c]pyrrole) (Poly-DPP):  A Deeply Colored Polymer with Unusually Large Stokes Shift

  摘要：

  New pi-conjugated polymers are described, which entirely consist of aryl-aryl-coupled 1,4-diketo-2,5-dialkyl-3,6-diphenylpyrrolo[3,4-c]pyrrole (DPP) units. The alkyl groups are n-hexyl (4a) or 2-ethylhexyl (4b) groups. The polymers are synthesized using nickel-promoted and palladium-catalyzed one-pot coupling reactions starting from 1,4-diketo-2,5-dialkyl-3,6-di(4-bromophenyl)pyrrolo[3,4-c]pyrrole (dibromo-DPP) as monomer, or conventional palladium-catalyzed coupling of dibromo-DPP and the 3,6-bis(pinacolato)boronester derivative of DPP. Polymers exhibit molecular weights up to 33 000 and are excellently soluble in chloroform and toluene. Deep red solutions (lambda(max) of 4b: 525 nm) with intense red photoemission (lambda(max) of 4b: 632 nm) and unusually large Stokes shift up to 107 nm are obtained. Cyclic voltammetry indicates quasi-reversible oxidation and reduction behavior, the onset potentials of 4b are +1.03 and -0.74 V vs SCE, respectively. From these potentials, HOMO/LUMO levels of -5.47 and -3.70 eV, respectively, can be calculated. Good solubility and processability into thin films render the compounds suitable for electronic applications.

  diketopyrrolopyrrole core as the central acceptor unit, two oligomeric benzene or thiophene as the donor, and two isoindigo or benzothienoisoindigo as the weaker acceptor, were synthesized. The influence of the number of thiophene on optical physical, crystallinity, charge carrier mobility, the morphologies of blend films, electrochemical and photovoltaic properties was investigated.
