✦ Synopsis

Quaternary superionic conducting AgI-Ag20-(MoO3+As2Os) glasses with different dopant salt (Agl) contents were prepared by fast quenching of the melt into liquid nitrogen, and characterized by X-ray diffraction. Electrical conductivity studies on pressed pellets are reported. At room temperature (303 K), the highest conductivity, o = 1.65 x 10-2 S cmwas obtained for the glass with 60 mol.% of AgI. The Ag + ion concentration and the packing density for glasses were calculated. The conductivity variation with dopant salt is discussed based on the diffusion path model.

## Abstract We have prepared photoresponsive oligomers that have molecular weights of ca. 4500, 8000, and 16 000 g mol^–1^ via the free‐radical polymerization of 4‐[4‐alkylphenylazo]phenoxyalkyl acrylates. All of the oligomers possess bilayer smectic A (SmA) and smectic B (SmB) phases. Increasing t
