Interestingly, the U87 glioblastoma cell line showed inherent resistance to growth inhibition by all analogues (GI50 32 to >50 μM) while the A2780 cells were highly sensitive (GI50 3.8–0.34 μM), suggesting that the analogues developed herein may be valuable lead compounds for the development of ovarian carcinoma specific cytotoxic agents. The differences in amide versus ester cytotoxicity was consitent with esterase cleaveage to release the cytotoxic warhead.]]> Wed 11 Apr 2018 11:15:48 AEST ]]> Roll coated large area ITO- and vacuum-free all organic solar cells from diketopyrrolopyrrole based non-fullerene acceptors with molecular geometry effects https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:29615 (P3HT:Ph(DPP)₂, 0.48%) > (P3HT:Ph(DPP)₃, 0.31%). All devices present an open circuit voltage (Voc) higher than 1.0 V. For the roll-coated devices, the PCEs were found to fall in another order and with lower values (P3HT:Ph(DPP)₃, 0.54%) > (P3HT:Ph(DPP)2, 0.43%) > (P3HT:PhDMe(DPP)₂, 0.04%) and the highest Voc was 0.82 V. Our preliminary results highlight the influence of geometry, structure and processing on the performance of non-fullerene acceptors.]]> Sat 24 Mar 2018 07:32:06 AEDT ]]>
