“…A sealed reaction chamber was used for I 2 vapor adsorption on ZIF‐8. [ 55–57 ] Briefly, the sheets and rods were put into 1.5 mL micro‐centrifuge tubes (Eppendorf) and the discs were placed into 50 mL centrifuge tubes (Corning). 9/15/26 mg of crystalline iodine were placed in the bottom of tube in MAO+Z Group and 15 mg iodine in MAO Group.…”

Iodine has been known as an effective disinfectant with broad‐spectrum antimicrobial potency yet without drug resistance risk when used in clinic. However, the exploration of iodine for antibacterial therapy in orthopedics remains sparse due to its volatile nature and poor solubility. Herein, leveraging the superior absorption capability of metal–organic frameworks (MOFs) and their inherent photocatalytic properties, iodine‐loaded MOF surface is presented to realize responsive iodine release along with intracellular reactive oxygen species(ROS) oxidation under near‐infrared (NIR) exposure to achieve synergistic antibacterial effect. Iodine is successfully loaded using vapor deposition process onto zeolitic imidazolate framework‐8(ZIF‐8), which is immobilized onto micro arc oxidized titanium via a hydrothermal approach. The combination of NIR‐triggered iodine release and ZIF‐8 mediated ROS oxidative stress substantially augments the antibacterial efficacy of this approach both in vitro and in vivo. Furthermore, this composite coating also supported osteogenic differentiation of bone marrow stromal cells, as well as improved osseointegration of coated implants using an intramedullary rat model, suggesting improvement of antibacterial efficacy does not impair osteogenic potential of the implants. Altogether, immobilization of iodine via MOF on orthopedic implants with synergistic antibacterial effect can be a promising strategy to combat bacterial infections.

“…Recently, various organic and inorganic adsorbents have been used in the field of iodine capture, including activated carbon (AC), [12,13] inorganic porous materials, [14,15] and metal organic frameworks (MOFs). [16,17] However, their low efficiency, poor moisture stabilities, and high cost still limit these materials from practical iodine capture.…”

Capturing volatile radioactive nuclides including iodine (I129 or I131) is one of the major problems to be solved for environmental sustainability. Multiple types of functional microporous materials such as metal organic frameworks and covalent organic frameworks have been constructed for iodine emission control. However, most of the microporous materials are limited by their weak binding force with iodine and low stability, leading to low capture efficiencies. Herein, the synthesis of pyridyl conjugated microporous polymer networks with large surface areas (PCMP‐Y) up to 1304 m2 g−1 and high yields up to 95% via a simple Yamamoto cross‐coupling reaction, is reported. The PCMP‐Y carries amine and pyridine N groups which have stronger interactions with iodine molecules. The high specific surface areas and porosities of PCMP‐Y facilitate iodine capture, delivering a maximum adsorption capacity of 4.75 g g−1 in a short time (3 h), which is superior to a majority of porous materials reported. Moreover, the reversible desorption nature of PCMP‐Y capturing iodine imparts a platform for metal‐free heterogeneous catalyst, which can be applied to synthesize aminobenzothiazole medicines via O2‐promoted cascade reactions.
