We study whether the inflation is realized based on the radion gauge-Higgs potential obtained from the one-loop calculation in the 5-dimensional gravity coupled to a U (1) gauge theory. We show that the gauge-Higgs can give rise to inflation in accord with the astrophysical data and the radion plays a role in fixing the values of physical parameters. We clarify the reason why the radion dominated inflation and the hybrid inflation cannot occur in our framework.

A series of 2,6‐bis[aryl(alkyl)sulfonyl]anilines were synthesized by nucleophilic aromatic substitution of 2,6‐dichloronitrobenzene with various aryl or alkyl thiolates (benzyl‐, phenyl‐, 2‐naphthyl‐, and 2‐aminophenyl thiolate), followed by hydrogenation and subsequent oxidation. All prepared 2,6‐bis[aryl‐(alkyl)sulfonyl]anilines showed high fluorescence emissions in the solid state; X‐ray structures revealed well‐defined intramolecular hydrogen bonds, which served to immobilize the rotatable amino group and generate a fluorescence enhancement in addition to improved photostability. Moreover, absorption and fluorescence spectra showed redshifts in the order of benzyl
