tert-Butoxyacetylene is shown to undergo Sonogashira coupling with aryl iodides to yield aryl-substituted tert-butyl ynol ethers. These intermediates participate in a [1,5]-hydride shift, which results in the extrusion of isobutylene and the generation of aryl ketenes. The ketenes are trapped

A platinum(II)-based, luminescent, metallo-supramolecular polymer (PolyPtL1) having an inherent dipole moment was synthesized via complexation of Pt(II) ions with an asymmetric ligand L1, containing terpyridyl and pyridyl moieties. The synthesized ligand and polymer were well characterized by various NMR techniques

Four pyrene-vinyl-tetraphenylethylene based conjugated materials were synthesized and characterized by FT-IR, NMR, and mass spectroscopy. The photophysical (including absorption, fluorescence, and fluorescence lifetime) and aggregation properties in tetrahydrofuran were investigated. The photophysical and aggregation behavior depends on the spacer, substituent

In this paper, a pyrene moiety is incorporated into a bolaamphiphile to form a novel molecule denoted PRB. Above the critical micelle concentration, PRB forms nanodisks in the aqueous solution. The addition of acetate ions induces a morphological change in

Phospholipid monomer and aggregation-induced emission (AIE) dye-based dimers are incorporated via reversible addition-fragmentation transfer polymerization to afford cross-linked zwitterionic fluorescent copolymers. Such copolymers are prone to self-assembly into fluorescent polymeric nanoparticles (FPNs) in physiological solution due to their amphiphilic nature.

  6. How should I store ChemDose® tablets?

    1 answer

    1. As with most catalysts and ligands, as a general precaution it is best to store them in a refrigerator and/or under an inert atmosphere to maintain activity. Some catalysts, such as Pd(dppf)Cl2·CH2Cl2, are more robust and can be handled in air without issue. Please refer to the ChemDose® label for specific handling of a given catalyst, ligand, or reagent.

  7. How should I dispose of spent ChemDose® tablets?

    1 answer

    1. They should be treated as solid waste, contaminated with reaction species. The matrix is non-toxic and environmentally benign.
