Synthesis and investigation of an erbium-containing photosensitive polymer

Abstract

Er organic complexes are generally used in polymer-based optical amplifiers by doping. This study presents a method for creating an Er-containing photosensitive polymer by free radical copolymerization. Two types of Er organic complexes containing polymeric reactivity groups are synthesized and investigated. Er(TTA) 2 (Phen)(MA), which has high photoluminescence, was polymerized with glycidyl 10 methacrylate (GMA) for use as a novel UV-written polymer material. Poly (GMA-co-Er(TTA) 2 (Phen)(MA) were prepared with different proportions of Er, and their spectroscopic properties were investigated in detail. Polymer films with the optimum proportion (the molar ratio of GMA and Er(TTA) 2 (Phen)(MA) was 115:1) exhibited good UV-light lithograph sensitivity, narrow near-infrared luminescence, good thermal stability (T d : up to 303 °C), and solvent resistance after crosslinking. Micro 15 patterns with smooth top surfaces were fabricated from the resulting polymer by direct UV exposure and chemical development.

“…Specic synthesis method and properties of the copolymer are given as ref. 22. By introducing an organic ligand (methacrylic acid) with excellent polymerization activity, carboxyl groups can be provided as coordinating groups for Er 3+ .…”

Synthesis and structural characterization of dinuclear cerium(III) and erbium(III) complexes of nicotinic acid or 2-aminobenzoic acid

“…Lanthanide complexes with carboxylic acids have been studied extensively because of their interesting photophysical and structural properties [1-6] and due to their potential applications in various fields, e.g., luminescence [6][7][8][9][10], diagnostics [11,13], catalysis [13,14] and materials chemistry [15][16][17][18][19][20]. The lanthanide metals are defined as classical hard acids, and thus have a high affinity to bind with hard donors, for example, ligands containing oxygen atoms especially, carboxylates [8].…”

Organic thin film transistors with novel photosensitive polyurethane as dielectric layer

“…Photosensitive solution-processable materials are considered viable alternative materials that can simplify procedures and reduce the manufacturing costs of large-area electronic applications. 27,28 In particular, solution-processable polyurethane has attracted considerable attention, due to high tensile strength, excellent abrasion resistance and good mechanical properties. 29 In this work, to afford a photosensitive cross-linking solution-processable material, we design and synthesis a novel monomer that contained hydroxy and olen groups.…”
