Pyrene-Derived Novel One- and Two-Component Organogelators
2003 / Chemistry A European JournalA new class of alkyl-chain-appended pyrene derivatives 4–14 were synthesized and evaluated for their gelation abilities. Depending on the nature of the linking group, these compounds gelated a number of organic solvents, either in the presence or in the absence of the acceptor molecule 2,4,7-trinitrofluorenone (TNF). Compounds with ester, ether, or alkyl link...

Optical characteristics of PtOEP and Ir(ppy) triplet-exciton materials for 3 organic electroluminescence devices
2003 / Thin Solid FilmsAbsorption and magnetic circular dichroism spectra of PtOEP and Ir(ppy)3 films evaporated on fused silica substrate are studied at 13–320 K. The characteristics of absorption bands related with the spin triplet and singlet states are clarified. The energy states of the absorption bands are identified, e.g. relatively weak absorption bands at 485 and 452 nm of...

Supramolecular GAG-like Self-Assembled Glycopeptide Nanofibers Induce Chondrogenesis and Cartilage Regeneration
2016 / BiomacromoleculesGlycosaminoglycans (GAGs) and glycoproteins are vital components of the extracellular matrix, directing cell proliferation, differentiation, and migration and tissue homeostasis. Here, we demonstrate supramolecular GAG-like glycopeptide nanofibers mimicking bioactive functions of natural hyaluronic acid molecules. Self-assembly of the glycopeptide amphiphile molecu...

New Red-Emitting Conjugated Polyelectrolyte: Stabilization by Interaction with Biomolecules and Potential Use as Drug Carriers and Bioimaging Probes
2016 / ACS Applied Materials and InterfacesThe design and development of fluorescent conjugated polyelectrolytes (CPEs) emitting in the red region of the visible spectrum is at present of great interest for bioimaging studies. However, despite the wide variety of CPEs available, stable bright red-emitters remain scarce due to their low solubility and instability in aqueous media, consequently limiting their...
