Photo-induced cancer therapy,such as photodynamic therapy(PDT) or photothermal therapy(PTT) treatment has shown great promise in precision nanomedicine owing to their selectivity,low systemic toxicity,negligible drug resistance,and non-invasive modality.1-3 In this presentation,we will demonstrate wavelength-dependent photoconversion regulation of Bodipy fluorophores through polymeric vesicles for either PDT or PTT treatment(Scheme 1).Bodipy is assembled with the terpolymer into polymeric vesicles in the conformation of both J-type and H-type aggregates,causing the red-shifted absorption into the near-infrared(NIR) region,low radiative transition,and ideal resistance to *** 660 nm irradiation,the vesicles mainly display remarkable singlet oxygen quantum yield through singlet-to-triplet transition,thereby leading to abundant intracellular singlet oxygen at the tumor for effective ***,under 785 nm irradiation,they primarily possess distinct photothermal conversion efficiency through non-radiative transition together with mild singlet oxygen generation,thus leading to potent hyperthermia at the tumor for robust PDT-synergized ***,the vesicles have preferable cellular uptake,effective cytoplasmic drug translocation through singlet oxygen-mediated lysosomal disruption,and enhanced tumor accumulation,which contribute to the total tumor ablation without any regrowth.4

Special research attention has been paid to phosphorus-containing materials and their corresponding applications. This mini review considers recent publications devoted to the "living"/controlled radical(co)polymerization of phosphorus-containing monomers. In addition, different properties of the polymers involved in the phosphonate group in various chemical environments are demonstrated, and their potential applications are briefly discussed.

We demonstrate here seven pure cyclic samples, which belongs to two series of oligoesters, cyclic oligo(trimethylene terephthalate)s (COTTs) and cyclic oligo(butylene terephthalate)s (COBTs), showing odd-even effect of degree of oligomerization (repeating units number) on properties. The pentamer of COTT and trimer of COBT show much lower melting temperature, and the trimer of COTT and trimer of COBT show significant lower refractive index, which can be ascribed to the low packing density of cyclic oligoesters with odd number of degree of oligomerization. Our results reveal the discrete property change as a function of cyclic size of oligomers, which can be used to design materials with special properties.

Nanostructured polyion complexes (PICs) are appealing in biomaterials applications. Yet, conventional assembly suffers from the weakness in scale‐up and reproducibility. Only a few low‐dimensional PICs are available to date. Herein we report an efficient and scalable strategy to prepare libraries of low‐dimensional PICs. It involves a visible‐light‐mediated RAFT polymerization of ionic monomer in the presence of a polyion of the opposite charge at 5–50 % w/w total solids concentration in water at 25 °C, namely, polymerization‐induced electrostatic self‐assembly (PIESA). A Vesicle, multi‐compartmental vesicle, and large‐area unilamellar nanofilm can be achieved in water. A long nanowire and porous nanofilm can be prepared in methanol/water. An unusual unimolecular polyion complex (uPIC)‐sphere‐branch/network‐film transition is reported. This green chemistry offers a general platform to prepare various low‐dimensional PICs with high reproducibility on a commercially viable scale under eco‐friendly conditions.
