“…Lin et al reported the polymerization of urushiols with UV light in the presence of transition metals, such as Cu II . This improved the thermal stability of the lacquer by TG analysis, likely due to coordination between the catechol moieties and the metal center 238. Urushiol composites with micro‐ and nanoparticles have been recently reported by the same authors.…”

Abstract.Catechols are found in nature taking part in a remarkably broad scope of biochemical processes and functions. Though not exclusively, such versatility may be traced back to several properties uniquely found together in the o -dihydroxyaryl chemical function; namely, its ability to establish reversible equilibria at moderate redox potentials and pHs and to irreversibly cross-link through complex oxidation mechanisms; its excellent chelating properties, greatly exemplifi ed by, but by no means exclusive, to the binding of Fe 3 + ; and the diverse modes of interaction of the vicinal hydroxyl groups with all kinds of surfaces of remarkably different chemical and physical nature. Thanks to this diversity, catechols can be found either as simple molecular systems, forming part of supramolacular structures, coordinated to different metal ions or as macromolecules mostly arising from polymerization mechanisms through covalent bonds. Such versatility has allowed catechols to participate in several natural processes and functions that range from the adhesive properties of marine organisms to the storage of some transition metal ions. As a result of such an astonishing range of functionalities, catechol-based systems have in recent years been subject to intense research, aimed at mimicking these natural systems in order to develop new functional materials and coatings. A comprehensive review of these studies is discussed in this paper.

“…In the infrared spectrum of SPS, the characteristic absorption peak of sulfonic acid group appeared at 1183 cm −1 , which indicated that the reaction of concentrated sulfuric acid with polystyrene resulted in sulfonated polystyrene. Compared to PS and SPS spectra, 1637 and 1607 cm −1 were the double peaks of urushiol‐specific “crab legs” in the IR spectra of UPr/PS core‐shell composite microspheres . Meanwhile, the characteristic absorption peak of the sulfonic acid group in 1183 cm −1 was weakened because of the reaction between Pr 3+ and sulfonic acid groups.…”

Urushiol praseodymium‐polystyrene (UPr‐PS) Janus composite particles were synthesized by emulsion swelling assisted protruding from UPr/PS core‐shell composite microspheres. The effects of sulfonated time and the outer electronic configuration of metal on the shell of urushiol metal/PS composite microspheres, together with the effects of monomer type, monomer dosage and swelling time on the swelling behaviour, were studied. The morphology, chemical composition and thermal performance of UPr/PS core‐shell composite microspheres and UPr‐PS Janus composite particles were studied by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X‐ray analyzer (EDX), Thermogravimetric analysis (TG) and infrared spectrometer (IR). Results showed that the morphology could be controlled by the metal kind, the sulfonated time, the monomer type, the monomer dosage and the swelling time. Attributing to the novel anisotropic structure, the UPr‐PS Janus composite particles will be expected to be applied in oriented catalyst. POLYM. ENG.

“…Optimization of the irradiation conditions improved the finish quality of the UV-cured lacquer, which showed better chemical and solvent resistance than laccase-cured ones [87]. This improved the thermal stability of the lacquer according to TG analysis, which is likely due to coordination between the catechol moieties and the metal center [96]. Lin et al reported the polymerization of urushiols with UV light in the presence of transition metals, such as Cu II .…”

A prime example of how biomaterials can inspire their fabricated counterparts is the case of catechol-based materials. Catechols are aromatic derivatives with two adjacent (ortho-) hydroxyl groups; they are ubiquitous in nature, taking part in a remarkable range of processes and functions. This functional versatility can be explained considering that catechols can act as weak acids and, simultaneously, as easily oxidizable reducing agents. In addition, the presence of two hydroxyl groups in vicinal positions in the aromatic ring makes them ideal for bidentate coordination and intermolecular interactions.Intense research has been aimed at mimicking the natural roles of catechols by developing new functional materials. This chapter will focus on past and recent studies involving the design, development, and biomimetic use of synthetic molecules and materials with catechols present in their structure, mainly in the fields of biomedicine, analytical, nanotechnology, and materials science, and showing the potential of this chemical functionality to afford promising candidate structures for technologically relevant applications.This chapter is structured considering the main functional roles of the catechol moiety in the molecules and materials fabricated, either as individual molecules or as part of a polymeric backbone. Thus, the three first sections are devoted to cases where catechols act as linkers between: macroscopic surfaces, acting as adhesives (Section 11.2); macroscopic surfaces and functional molecules (Section 11.3); and outer parts of micro-or nanoscopic structures and functional molecules (Section 11.4). Section 11.5 is focused in the role of catechols as constituent blocks of functional 2D or 3D scaffolds and structures. Next, the chelating properties of catechols and their function for metal sequestration are addressed in Section 11.6. Finally, the two last sections are centered on their presence in different sensors (Section 11.7) and electronic devices (Section 11.8), owing to the redox features of the catechol/quinone system.
