Themed collection Organic Electronics – Ecofriendly and/or sustainable materials, processes, devices, and applications

Professor Gregory C. Welch introduces the Journal of Materials Chemistry C and Materials Advances joint themed collection on Organic Electronics – Ecofriendly and/or sustainable materials, processes, devices, and applications.

This article provides a review of various types of self-rechargeable batteries powered by ubiquitous clean and sustainable energy sources.

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.

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.

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.

Design, synthesis, and characterization of an electron deficient N-H functionalized perylene diimide, with halogen-free solvent solubility, for air-stable transistor operation.

Phosphorus-modified Pt@Cu (Pt/P@Cu) was fabricated through a one-step method as a self-standing electrocatalyst, leading to increased surface activity sites, reduced charge transfer resistance and enhanced HER performance in neutral medium.

Study of the photophysical, electrochemical and photoconductive properties of SPS-PY-PT and a comparative analysis with PY-PT-Un. In addition, the ACQ and AIE phenomena and time-resolved microwave conductivity (TRMC) are analysed.

In order to develop more atom-economical deposition methods for polymer semiconductors, we investigated physical supercritical fluid deposition (p-SFD) to form thin films of a popular bithiophene semiconducting polymer (PBTTT).

We investigate the effect of the polyelectrolyte lithium poly(styrene sulfonate) (Li:PSS) on the electronic band structure of organic solar cells and find that it functions as a hole transport layer, allowing improved efficiency and device stability.

Chalcogen-substituted PCBM derivatives are a promising approach to enhance power efficiency in ternary organic solar cells (TOSCs).

Light-emitting transistors (LETs) couple the switching function of a transistor with the light-emitting function of LEDs. We demonstrate improved light out-coupling efficiency in LETs using oxide – metal – oxide type semitransparent electrodes.

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.

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).

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.

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.

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.

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.
