Multi-Step and Switchable Energy Transfer in Photoluminescent Organosilicone Capsules.

Light-harvesting is of vital importance for many events, such as photosynthesis. To efficiently gather and transfer solar energy, delicate antenna is needed, which has been achieved by algae and plants. However, construction of efficient light-harvesting systems using multiple, artificial building blocks is still challenging.

Combination of photosensitizer and immune checkpoint inhibitors for improving the efficacy of tumor immunotherapy.

As a new type of antitumor strategy, the combined application of photodynamic therapy and immunotherapy will be a breakthrough in the field of tumor therapy. In this study, PD-L1McAb&HMME@Clip is used as the carrier to improve the low tumor response rate of immune checkpoint inhibitors. Firstly, by passive targeting technology, the carrier is delivered to the tumor site to increase the local drug concentration.

Artificial Light-Harvesting System with White-Light Emission in a Bicontinuous Ionic Medium.

Artificial light-harvesting systems (ALHSs), which are closely related to Förster resonance energy transfer (FRET), are among the most attractive scientific topics during the past few decades. Specifically, binary ALHSs that are composed of a fluid donor and acceptor have a simplified composition and high number density of the donor units. However, largely due to the difficulty in obtaining a fluid donor, investigation of these systems is still quite limited, especially for the ionic systems.

formation and dispersion of lanthanide complexes in wormlike micelles.

Lanthanide-containing, water-based fluids normally suffer from low photoluminescent (PL) and/or colloidal stability, which greatly hinders their applications. Herein, we report the preparation of PL fluids which contain formed europium complexes in aqueous solution. The strategy first relies on the construction of wormlike micelles by mixing a zwitterionic surfactant (tetradecyldimethylaminoxide, CDMAO) and a tridentate ligand for a lanthanide cation (2,6-dipicolinic acid, DPA) in water.

Metal-Organic Gels from Silver Nanoclusters with Aggregation-Induced Emission and Fluorescence-to-Phosphorescence Switching.

Luminescent metal nanoclusters (NCs) are emerging as a new class of functional materials that have rich physicochemical properties and wide potential applications. In recent years, it has been found that some metal NCs undergo aggregation-induced emission (AIE) and an interesting fluorescence-to-phosphorescence (F-P) switching in solutions. However, insights of both the AIE and the F-P switching remain largely unknown.
