New Type of Eco‐Friendly Polymeric Dye by Covalently Bonding Anthraquinone into Polyphenylsulfone

Abstract

Eco-friendly polymeric dyes with excellent thermal stability, good mechanical performance, and robust chemical stability are highly desired for their diverse and practical applications in food, medicine, electronics and aerospace, etc. However, it remains a big challenge to develop them. Herein, a novel type of eco-friendly polymeric dye is fabricated by covalently bonding anthraquinone chromophores onto polyphenylsulfone at a molecular level. The obtained polymeric dyes exhibit excellent thermal stability, with a weight loss of 5% at temperatures above 500 °C in air and negligible changes in both color appearance and transparency after being treated at 200 °C in air for 8 h, good mechanical performance with a tensile strength around 70 MPa, and robust chemical stability with demonstrated insolubility and very outstanding colorfastness and anti-permeability against strong acidic or basic solutions for 7 days at room temperature. These outstanding properties make these polymeric dyes suitable for use in harsh conditions, exceeding existing polymeric dyes, which makes them good to use in some special engineering plastics.

Nonlinear Optical Stability of Polyphenylsulfone (PPSU)‐Containing Anthraquinones with High Transmittance

“…In this work, three different types of anthraquinone chromophores were selected for preparing PPSU with red, blue, and yellow colors using the same nucleophilic polycondensation method as in our previous work, and the molecular formulas of the three polymers were exhibited in Figure . [ 25 ] The three polymers were named RPPSU, BPPSU, and YPPSU.…”

“…In our previous study, [ 25 ] three kinds of polymers (yellow polyphenylsulfone (YPPSU), red polyphenylsulfone (RPPSU), and blue polyphenylsulfone (BPPSU)) were synthesized by covalently bonding three types of anthraquinone chromophores onto PPSU via nucleophilic polycondensation reactions. The obtained polymeric materials exhibited excellent thermal and chemical stability with outstanding color fastness and antipermeability against strong acidic or basic solutions.…”

Recent Advancements in Polyphenylsulfone Membrane Modification Methods for Separation Applications

“…Thus, the membrane bulk was not significantly affected. However, the membrane surface properties were significantly improved and demonstrated better chemical and structural stabilities [21,83,[167][168][169]. We further review the techniques of physical and chemical surface modification of the PPSU membrane surface in Figure 11.…”

Synthesis of anthraquinone-based electroactive polymers: a critical review

“…This compound anthraquinone was already synthesized with the nitric acid oxidation of anthracene by Laurent After the structure elucidation of anthraquinone (AQ), electrochemical investigations of the compound were made by different scientist groups because of their incredible reversible redox reaction ability. The anthraquinone moiety has been used commendably not only in energy storage systems but also in dyes [50], paint [51] and medicinal industries [52,53]. Yao and coworkers [45] worked on anthraquinone, utilizing its exceptional redox ability in the rechargeable battery system.…”

“…Back in 2015, some researchers inspected two polyimides (PI) having anthraquinone group as a connection unit. Two polyimides were prepared by the imidization polymerization of two different compounds that are PMDA (51) and NTCDA (52) with anthraquinone derivative Fig. 12.…”
