Advances in applying C–H functionalization and naturally sourced building blocks in organic semiconductor synthesis
This review presents the recent advances in the synthesis of organic semiconductors using C–H functionalization and naturally sourced building blocks to facilitate the large-scale production and commercialization of organic semiconductors.
Low-cost materials for organic solar cells
This review summarizes the recent advances in low-cost materials for OSCs from the aspects of the synthetic method, active materials, interfacial materials and processing solution.
Peptide-based novel small molecules and polymers: unexplored optoelectronic materials
Optoelectronic devices such as photovoltaics (solar cells), organic light-emitting diodes (OLEDs), thin-film transistors, and electrochromism based on peptide molecular/materials and their strategic design.
An air-stable n-type bay-and-headland substituted bis-cyano N–H functionalized perylene diimide for printed electronics
Design, synthesis, and characterization of an electron deficient N-H functionalized perylene diimide, with halogen-free solvent solubility, for air-stable transistor operation.
Improving the charge transport performance of solution-processed organic field-effect transistors using green solvent additives
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.
2,9-Dibenzo[b,def]chrysene as a building block for organic electronics
A new series of three donor–acceptor conjugated polymers based on a low-cost, easily accessible vat dye called Vat orange 1 have been prepared. The polymers have bandgap values ranging from 1.61 to 1.86 eV.
Chalcogen-substituted PCBM derivatives as ternary component in PM6:Y6 solar cells
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.
Temperature-dependent morphology-electron mobility correlations of naphthalene diimide-indacenodithiophene copolymers prepared via direct arylation polymerization
A series of defect-free n-type copolymers poly(naphthalene diimide-alt-indacenodithiophene) P(NDI-IDT) comprising alternating naphthalene diimide (NDI) and indacenodithiophene (IDT) units is prepared using atom-economic direct arylation polycondensation (DAP).
Fabrication of an autonomously self-healing flexible thin-film capacitor by slot-die coating
Flexible self-healing pressure sensors were prepared by slot-die onto a flexible substrate, and were characterized using multiple tools to investigate their response to mechanical deformation and their properties before and after self-healing.
Impact of subtle change in branched amino acid on the assembly and properties of perylene bisimides hydrogels
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.
