We apply two three-element arrays consisting either of different GFPs or of charged fluorescent poly(p-aryleneethynylene)s as a successful, hypothesis-free tongue that discriminates more than 30 whiskies according to their country of origin, brand, blend status, and taste. The underlying mechanism is the modulation of the fluorescence intensity of the elements of the sensor array by the different whiskies. Age, country of origin, blend status, and elements of taste were discriminated by the two very different tongues.

Lignin and plant oils—two highly available renewable feedstocks—are cured via olefin metathesis to produce thermosetting polymer films with tunable mechanical properties. Therefore, an organosolv lignin, allylated in a recently described sustainable approach, is used. For the first time, unmodified plant oils are reacted with a lignin derivative. An increasing lignin content as well as an increasing amount of polyunsaturated fatty acids in the plant oil structure lead to higher Young's moduli and higher cross‐linking density. Stress–strain measurements reveal ductile behavior of the prepared films. Only a lignin content over 70% leads to brittle materials. To improve the overall sustainability of this approach, dimethyl carbonate is investigated as sustainable solvent for film formation, leading to materials with similar Young's moduli and tensile strength, but lower degree of cross‐linking if compared to the more volatile solvent dichloromethane.

The synthesis and quenching behavior of a series of water-soluble, carboxylate-carrying phenyleneethynylene oligomers-monomer to tetramer-and their polymers are reported; their quenching behavior with different test analytes (paraquat, lead salts, mercury salts, picric acid, methylpyridinium iodide) in water were investigated, and the results were compared to that of the conjugated polymer. Significant but analyte-dependent enhancement effects were found. For monovalent quenchers, only the molecular wire effect applies, but for divalent quenchers multivalency effects are also important.

Front Cover: Lignin and plant oils – two highly available renewable feedstocks – are cured via olefin metathesis to produce thermosetting polymer films with tunable mechanical and thermal properties. An increasing lignin content as well as an increasing amount of polyunsaturated fatty acids in the plant oil structure leads to higher material strength, higher cross‐linking density and lower glass transition temperature.
