Ultrafast Dynamics of Diketopyrrolopyrrole Dimers. [PDF]
J Comput ChemDiketopyrrolopyrroles (DPPs) have attracted attention for their potential applications in organic photovoltaics due to their tunable optical properties and charge-carrier mobilities. In this study, we investigate the excited-state dynamics of a DPP dimer using time-dependent density functional theory (TDDFT) and nonadiabatic molecular dynamics ...

Air-Stable n-channel Diketopyrrolopyrrole−Diketopyrrolopyrrole Oligomers for High Performance Ambipolar Organic Transistors [PDF]
ACS Applied Materials & Interfaces, 2016 n-channel organic semiconductors are prone to oxidation upon exposed to ambient conditions. Herein, we report design and synthesis of diketopyrrolopyrrole (DPP)-based oligomers for ambipolar organic thin-film transistors (OFETs) with excellent air and bias stability at ambient conditions.
