The concept of splayed, hyperthin polyelectrolyte multilayers (PEMs) is introduced in which a bulky, hydrophilic and charged pendant group is used to increase the gas permeability of a PEM without reducing its permeation selectivity. Proof of principle studies are reported using nm-thick PEMs made from poly(sodium 4-styrene sulfonate) () and poly(allylamine hydrochloride) () bearing bulky cobal...

The title compound, C(16)H(12)O(2), was synthesized from naphthalene-2,7-diol and prop-2-ynyl 4-methyl-benzene-sulfonate in the presence of sodium hydride. The crystal packing exhibits inter-molecular non-classical C-H⋯O hydrogen bonds and C-H⋯π inter-actions.

The title compound, [Na(4)(CH(2)O(6)S(2))(2)(H(2)O)(5)](n), was crystallized from an aqueous solution. The sodium ions are surrounded and bridged by O atoms from coordinated water mol-ecules and sulfonate ions in a three-dimensional neutral network. The crystal structure is also stabilized by an intricate system of hydrogen bonds.

The aerobic organocatalytic oxidation of alcohols was achieved by using water-soluble sodium anthraquinone sulfonate. Under visible-light activation, this catalyst mediated the aerobic oxidation of alcohols to aldehydes and ketones. The photo-oxyfunctionalization of alkanes was also possible under these conditions.
