Two pyridone derivatives, bearing the pyridinium moiety (1), or dimethylpyridinium (2), have been synthesized and their crystal structures determined. The compounds crystalize in hydrated zwitterionic forms with either two (1·2H2O) four (2·4H2O) water molecules. networks contain different types of clusters, generated into channels, incorporating them network by sandwiching. type channel depends...

Liposomes (lipid vesicles) are often considered to be a versatile tool for the synthesis of advanced materials, as they allow various control mechanisms tune materials’ properties. Among diverse calcium phosphates (CaPs) and carbonates (CaCO3) using liposomes has attracted particular attention in development novel (bio)materials biomineralization research. However, preparation materials not yet...

Electron transfer and delocalization of the pi systems were investigated in mono- and dinuclear Ru complexes with the zwitterionic ligand L = N,N'-diisopropyl-2-amino-5-alcoholate-1,4-benzoquinonemonoiminium.

A new and stable zwitterionic (neutral) radical and its perchlorate salts exist as diamagnetic pi-dimers in solution, and pi-stacking 1D chains with interesting magnetic and luminescent properties in solid state.

A new water-soluble receptor 1 has been synthesized and it showed selective recognition of zwitterionic arginine in aqueous media. Moreover, the receptor 1 could be regard as a facile tool for protein labeling and quantitative determination (LOD = 15 nM).

We report a versatile approach for the design of substrate-independent low-fouling surfaces via mussel-inspired immobilisation of zwitterionic peptides. Using mussel-inspired polydopamine (PDA) coatings, zwitterionic glutamic acid- and lysine-based peptides were immobilised on various substrates, including noble metals, metal oxides, polymers, and semiconductors. The variation of surface chemis...

In the title compound, [Zn(C(14)H(17)N(5)O(3))(C(9)H(4)O(6))(H(2)O)(2)]·H(2)O, the complex mol-ecule exists in a zwitterionic form. The Zn(II) ion exhibits a distorted tetra-gonal-pyramidal geometry, being coordinated by two O atoms from the zwitterionic 8-ethyl-5-oxo-2-(piperazin-4-ium-1-yl)-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxyl-ate (L) ligand, one O atom from the 5-carb-oxy-benzene-1...
