The results showed that 8% SDS-BiOI microspheres possessed the homogeneous morphology, larger specific surface area and more oxygen vacancies compared with the pure BiOl. Moreover, the adsorption efficiency of rhodamine B (RhB) and methyl orange (MO) for 8% SDS-BiOI reached almost 96.4% and 79.4%, respectively. It was found that the oxygen vacancy induced by SDS improved adsorption performance of BiOI due to the enhanced electrostatic interaction.展开更多

By precisely controlling the participation of donor and acceptor units, a highly soluble organic cage with delayed fluorescence was obtained for the first time. More interestingly, due to the restriction of intramolecular flipping by locking the building blocks within a rigid framework, this emissive organic cage further showed narrowband ultra-deep blue electroluminescence emission at 413 nm with a full-width at half-maximum of 35 nm. This finding not only expands the family of electroluminescent organic cages, but also opens up a new platform for delayed fluorescence materials with high solubility and color purity.展开更多
