Green solvent additives were employed as non-solvents in binary solvent systems to enable the pre-aggregation of organic semiconductors and enhance the electrical performance of organic field-effect transistors and complementary-like inverters.
Synthesis of push–pull triarylamine dyes containing 5,6-difluoro-2,1,3-benzothiadiazole units by direct arylation and their evaluation as active material for organic photovoltaics
Direct (hetero)-arylation was used to prepare two push–pull molecules. Optimization of the experimental coupling conditions and their preliminary evaluation as active materials in simple air-processed organic solar cells are reported herein.

We investigate how apparent slight changes to the chemical structure of amino acid-functionalised perylene bisimides (PBIs) affect the self-assembled aggregates formed and their resulting physical and optical properties.
