Reactions between the ethylene groups in the backbone of conjugated polymers under UV illumination and heat treatment result in the cross-linking of the main polymer chains. The cross-linking leads to two simultaneous results in the polymer: excellent solvent resistance and increased bandgap. Using this reaction, three-color polymer light-emitting diodes (PLEDs) with a multi-layer structure can be easily realized by a dry photo-pattern in an active-gas-free environment. Multi-layer blue devices with dramatically enhanced efficiency can also be achieved conveniently.

Non-viral vectors have gained recognition for their ability to enhance the safety of gene delivery processes. Among these, polyethyleneimine (PEI) stands out as the most widely utilized cationic polymer due to its accessibility. Traditional methods of modifying PEI, such as ligand conjugation, chemical derivatization, and cross-linking, are associated with intricate preparation procedures, limited transfection efficiency, and suboptimal biocompatibility.

Background/objectives: Leukocytes play a significant role in both acute kidney injury (AKI) and chronic kidney disease (CKD), contributing to pathogenesis and tissue damage. The process of leukocyte infiltration into the inflamed tissues is mediated by the interactions between the leukocytes and cell adhesion molecules (CAMs, i.e.

Optically responsive materials are applied in sensing, actuators, and optical devices. One such class of material is dye-doped liquid crystal polymers that self-assemble into cholesteric mesophases that reflect visible light. We report here the synthesis and characterization of a family of linear and mildly crosslinked terpolymers prepared by the ROMP of norbornene-based monomers.
