Three molecular semiconductors are compared and evaluated in organic field-effect transistors solar cells. The molecules constructed from the dyes diketopyrrolopyrrole (DPP), perylene diimide (PDI), N-(alkyl)benzothioxanthene-3,4-dicarboximide (BTXI). compound PDI–DPP–PDI (1) has previously been reported used as a nonfullerene acceptor. compounds PDI–DPP–BTXI (2) BTXI–DPP–BTXI (3) were synthesized using direct (hetero)arylation methods fully identified NMR spectroscopy mass spectrometry. All three characterized UV–visible spectroscopy, cyclic voltammetry, density functional theory calculations. Increasing BTXI content results progressive destabilization of electronic energy levels. For all compounds, no significant changes optical absorption spectra observed when to combination constituent spectra.

Direct (Hetero)Arylation for the Synthesis of Molecular Materials: Coupling Thieno[3,4-c]pyrrole-4,6-dione with Perylene Diimide to Yield Novel Non-Fullerene Acceptors for Organic Solar Cells

Molecules, Journal Year: 2018, Volume and Issue: 23(4), P. 931 - 931

Published: April 17, 2018

Herein we report on the synthesis of an N-annulated perylene diimide (PDI) disubstituted thieno[3,4-c]pyrrole-4,6-dione (TPD) molecular acceptor (PDI–TPD–PDI) by direct heteroarylation (DHA) methods. Three sets DHA conditions that explore effects solvent, temperature, and catalyst were employed to find optimal for two PDI–TPD–PDI derivatives. We then selected one use as a non-fullerene in organic solar cell devices with donor polymer PBDB-T. Active layer bulk-heterojunction blends modified using several post-deposition treatments, including thermal annealing, solvent vapour high boiling additives. It was found active layers cast from o-dichlorobenzene 3% v/v diphenylether additive yielded films adequate phase separation, subsequently gave best performance, power conversion efficiencies greater than 3%.
