@article { , title = {Highly electron deficient diketopyrrolopyrroles}, abstract = {The synthesis, spectroelectrochemical and structural characteristics of highly electron-accepting diketopyrrrolopyrrole (DPP) molecules with adjoining pyridinium rings is reported, along with an assessment of their toxicity, which is apparently low. The compounds show reversible electrochemistry and in one subfamily a massive increase in molar extinction coefficient upon electrochemical reduction.}, doi = {10.1039/d2cc06770f}, eissn = {1364-548X}, issn = {1359-7345}, issue = {12}, journal = {Chemical Communications}, pages = {1613-1616}, publicationstatus = {Published}, publisher = {Royal Society of Chemistry (RSC)}, url = {https://nottingham-repository.worktribe.com/output/15940541}, volume = {59}, keyword = {Materials Chemistry, Metals and Alloys, Surfaces, Coatings and Films, General Chemistry, Ceramics and Composites, Electronic, Optical and Magnetic Materials, Catalysis}, year = {2023}, author = {Humphreys, Joshua and Malagreca, Ferdinando and Hume, Paul A. and Davies, E.
