title: Efficient two- to five-photon excited violet emission of calix[4]arene-based multiple donor-acceptor assembly.
abstract: Remarkably strong multiphoton, from two- to five-photon, upconverted violet fluorescence is first observed on a calix[4]arene-based multi-dipolar assembly which is strongly enhanced as compared to that of the corresponding dipolar counterparts.
