  • Patent number: 10018623
    Abstract: Described are metal complexes for the selective detection of ascorbic acid or ascorbate. The metal complexes act as molecular sensors, and are useful in detecting ascorbate in live biological samples, commercial samples, or both. The selective ascorbate sensing involves an ascorbate-selective bond cleavage reaction. The bond cleavage is not limited to the construction of molecular sensors, but also includes other stimuli-responsive materials, i.e., materials that adopt a physical state, such as gel formation, upon ascorbate-selective bond cleavage of the metal complexes.

It is disclosed that significant electronic effect of different substituted 2-alkoxybenzylidene ligands on the catalytic activity and stability of corresponding carbene ruthenium complexes, some of novel ruthenium complexes in the invention can be broadly used as catalysts highly efficient for olefin metathesis reactions, particularly in ring-closing (RCM), ring-opening (ROM), ring-opening metathesis polymerization (ROMP) and cross metathesis (CM) in high yield. The invention also relates to preparation of new ruthenium complexes and the use in metathesis.
