Article Abstract

The design of new generation light-harvesting systems based on conjugated polymer nanoparticles (PNPs) is an emerging field of research to convert solar energy into renewable energy. In this Perspective, we focus on the understanding of the light harvesting processes like exciton dynamics, energy transfer, antenna effect, charge carrier dynamics, and other related processes of conjugated polymer-based functional nanomaterials. Spectroscopic investigations unveil the rotational dynamics of the dye molecules inside of PNPs and exciton dynamics of the self-assembled structures. A detailed understanding of the cascade energy transfer for white light and singlet oxygen generation in multiple fluorophores containing a PNP system by time-resolved spectroscopy is highlighted. Finally, ultrafast spectroscopic investigations provide direct insight into the impacts of electron and hole transfer at the interface in the hybrid materials for photocatalysis and photocurrent generation to construct efficient light-harvesting systems.

The construction of single-component, white-light-emitting, conjugated polymers always utilizes fluorescence resonance energy transfer (FRET) for efficient emission. However, the main challenges in developing such materials primarily come from the effects of aggregation states during solution processing and the precise structural control required for the synthesis of compounds. Both aspects can affect the FRET between different lumophores in white-light-emitting materials.

This study introduces a flexible and scalable charge-trapping intermediate layer of conjugated polymeric film comprising [PANI/PEDOT:PSS] between the [PVA/PDDA] triboelectric layer and graphene-based [PVA/GNP-PSS] electrode using the layer-by-layer (LbL) assembly method. By varying the deposition layers, the optimal coating layout was identified as 2 and 8 bilayers of intermediate and triboelectric layers, respectively. The triboelectric nanogenerator (TENG) fabricated with this optimal configuration achieved peak output voltage and current of 180 V and 9 μA, respectively, at 3 Hz and 5 N against PDMS.

Interconnecting EDOT-Based Polymers with Native Lignin toward Enhanced Charge Storage in Conductive Wood.

ACS Appl Mater Interfaces

December 2024

Laboratory of Organic Electronics, Department of Science and Technology, Linköping University, SE-601 74, Norrköping, Sweden.

The 3D micro- and nanostructure of wood has extensively been employed as a template for cost-effective and renewable electronic technologies. However, other electroactive components, in particular native lignin, have been overlooked due to the absence of an approach that allows access of the lignin through the cell wall. In this study, we introduce an approach that focuses on establishing conjugated-polymer-based electrical connections at various length scales within the wood structure, aiming to leverage the charge storage capacity of native lignin in wood-based energy storage electrodes.

N-nitrosodimethylamine (NDMA) was determined using a molecularly imprinted polymer (MIP)-based electrochemical sensor. Green-synthesized silver nanoparticles were functionalized with cysteamine to enhance their integration into the electrode surface, which was used to modify a glassy carbon electrode (GCE). Furthermore, a MIP-based electrochemical sensor was constructed via electropolymerization of 3-aminophenyl boronic acid (3-APBA) as a conjugated functional monomer in the presence of lithium perchlorate (LiClO) solution as a dopant, chitosan as a carrier natural polymer, and NDMA as a template/target molecule.
