Facile synthesis of unsymmetrical and π-extended furan-diketopyrrolopyrrole derivatives through C–H direct (hetero)arylation using a heterogeneous catalyst system
studies revealed that the highest occupied molecular orbital/lowest unoccupied molecular orbital energy levels of all the four compounds, CTDP (−5.03/−3.65 eV), BCTDP (−5.03/−3.65 eV), CFDP (−4.94/−3.65 eV), and BCFDP (−4.90/−3.62 eV) are well matched with PCBM and expected to be act as donor materials in small molecule bulk hetero junction organicsolarcells. All the compounds are thermally stable up
Two new conjugated electron-donor molecules employing planar diketopyrrolopyrrole (DPP) as the core building block acceptor unit and phenoxazine-capped acrylonitrile as arms are designed and synthesized. A very high power conversion efficiency (PCE) of 4.8 % is achieved, which is the highest reported so far in DPP–phenoxazine-based systems.
A NIR D–A–D structure of a ferrocene flanked diketopyrrolopyrrole derivative with a tetracyanobutadiene unit is synthesized for photoacoustic imaging-guided amplifying photothermal therapy.
