title: Photoresponsive multilayer spiral nanotubes: intercalation of polyfluorinated cationic azobenzene surfactant into potassium niobate.
abstract: The first successful synthesis of photoresponsive multilayer spiral nanotubes by the introduction of polyfluorinate cationic azobenzene derivative, trans-[2-(2,2,3,3,4,4,4-heptafluorobutylamino)ethyl]-{2-[4-(4-hexyphenylazo)-phenoxy]ethyl}dimethylammonium (abbreviated as C3F7-Azo+), into layered niobate interlayer I by a two-step guest-guest exchange method using the intercalation compound, methyl viologen (MV2+)-K4Nb6O17, as precursor is reported.
