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.
在基于
钙[4]炔的多双极组装体上首次观测到了从双光子到五光子的显著强多光子上转换紫色荧光,与相应的双极对应物相比,这种荧光得到了强烈的增强。
