Multimodality imaging based on multifunctional nanocomposites holds great promise to fundamentally augment the capability of biomedical imaging. Specifically, photoacoustic and fluorescence dual-modality is gaining much interest because their non-invasiveness complementary nature two modalities in terms resolution, depth, sensitivity, speed.

Abstract Two redox‐active porous organic frameworks (POFs) with a built‐in radical moiety (TEMPO) and hierarchical structures were synthesized through facile bottom‐up strategy studied as cathode materials for lithium–sulfur (Li−S) batteries. The sulfur loading in these two POFs reached 61 %, benefitting from their large pore volumes. Owing to the highly dense docking sites of TEMPO, could be covalently immobilized within networks efficiently inhibit shuttle effect, thereby significantly...
Highly efficient triplet photosensitizers (PSs) have attracted increasing attention in cancer photodynamic therapy where photo-induced reactive oxygen species (ROSs, such as singlet oxygen) are produced via singlet-triplet intersystem crossing (ISC) of the excited photosensitizer to kill cells. However, most PSs exhibit fatal defect a generally less-than-1% efficiency ISC and low yield ROSs, this strongly impedes their clinical application. In current work, new strategy enhance high...
