Abstract
In the past few decades, organosilicon fluorescent materials have attracted great attention in the field of fluorescent materials not only due to their abundant and flexible structures, but also because of their intriguing fluorescence properties, distinct from silicon-free fluorescent materials. Considering their unique properties, they have found broad application prospects in the fields of chemosensor, bioimaging, light-emitting diodes, etc. However, a comprehensive review focusing on this field, from the perspective of their catalogs and applications, is still absent. In this review, organosilicon fluorescent materials are classified into two main types, organosilicon small molecules and polymers. The former includes fluorescent aryl silanes and siloxanes, and the latter are mainly fluorescent polysiloxanes. Their synthesis and applications are summarized. In particular, the function of silicon atoms in fluorescent materials is introduced. Finally, the development trend of organosilicon fluorescent materials is prospected.

Research on the Factors Damaging Hydrogen Peroxide Low-Temperature Plasma Sterile Packaging Bags and the Control of Link Quality. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:4624912. [PMID: 36034945 PMCID: PMC9410775 DOI: 10.1155/2022/4624912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Accepted: 07/29/2022] [Indexed: 11/17/2022]
Abstract
Objective. After discussing the factors damaging hydrogen peroxide low-temperature plasma sterile packaging bags (hereinafter referred to as Tyvek packaging bags), the damage rate of Tyvek packaging bags is lowered through the control of link quality, so as to guarantee the quality of sterile packaging bags and the safety of patients. Methods. Design questionnaire and registration form by investigating 8606 instrument packaging bags sterilized by hydrogen peroxide low-temperature plasma from January 2019 to December 2019, the controllable factors damaging Tyvek packaging bags are analyzed from four aspects: instrument packaging, sterilization, transfer, and storage. By taking targeted interventions on 8155 instrument packaging bags sterilized from January 2020 to December 2020, the intervention effects of the key links and the damage rate are evaluated. Results. The main factors damaging Tyvek packaging bags mainly include improper transfer, storage, and management of instrument packing bags; improper use of instrument boxes; improper loading and uploading operations of sterilization; and the wrong size of packaging bags. For these factors, related intervention measures shall be adopted to control the link quality so as to lower the damage rate from 3.54% in the control group to 0.20% in the experimental group. The differences in damage rate are of statistical significance (
). Conclusion. Tyvek packaging bags are influenced by controllable factors. Through reasonable link control and standard operations, the sterile packaging bags can be kept sterile from the end of sterilization to the usage by patients, which guarantees the safety of patients and is worthy of reference.

Preparation and Properties of Benzylsulfonyl-Containing Silicone Copolymers via Ring-opening Copolymerization of Macroheterocyclosiloxane and Cyclosiloxane. Chemistry 2021; 27:7897-7907. [PMID: 33783909 DOI: 10.1002/chem.202100309] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Indexed: 11/07/2022]
Abstract
Ring-opening copolymerization (ROCP) of benzylsulfonyl macroheterocyclosiloxane (BSM) and five different cyclosiloxanes was systematically investigated. A general approach for the synthesis of benzylsulfonyl-containing silicone copolymers with various substituents, including methyl, vinyl, ethyl, and phenyl, was developed herein. A series of copolymers with variable incorporation (from 6 % to 82 %) of BSM were obtained by modifying the comonomer feed ratio and using KOH as the catalyst in a mixed solvent of dimethylformamide and toluene. The obtained copolymers exhibited various composition-dependent properties and unique viscoelasticity. Notably, the surface and fluorescent characteristics as well as the glass transition temperatures of the copolymers could be tailored by varying the amount of BSM. Unlike typical sulfone-containing polymers, such as poly(olefin sulfone)s, the prepared copolymers displayed excellent thermal and hydrolytic stability. The universal strategy developed in the present study provides a platform for the design of innovative silicone copolymers with adjustable structures and performance.
