“…Therefore, we finally chose ErTPM as the monomer to synthesize the target product through free radical polymerization with GMA. As shown in Fig.3B, GETPM 2 (curve b′) emits stronger characteristic luminescence than GETPM 3 (curve a′), and GETPM 1 (curve c′) in solid states were 25 excited at 390 nm.…”

“…As shown in Fig. 4, the emission spectrum of ErTPM (curve a) exhibits almost identical characteristics: emission peak is broad (1500-1600 nm) and peak position is at 1530 nm for Er complexes [25][26][27][28] . However, an interesting phenomenon occurred to 35 the polymer (curves b, c, and d).…”

“…6, the glass transition temperature (Tg) of GETPM 2 (curve a) is approximately 142 °C, and the endothermic peak of crosslinked GETPM 2 (curve b) is not obvious because of the high crosslinking density. The TGA 25 curves in Fig. 7 show that the decomposition temperatures (Td, about 5%) of GETPM 2 is 265 °C and that the crosslinked GETPM 2 has good thermal stability with only 5% weight loss up to 303 °C.…”

“…A growing demand exists for low-cost near-infrared (NIR) light sources for communications [3][4][5] . In recent years, Er-doped waveguide amplifiers (EDWAs) have aroused significant research attention in the field of telecommunications because the infrared emission 25 properties of Er 3+ ion at around 1530 nm is suitable for long distance communications 6-10 . The two main issues faced by current amplifiers, which rely on Er ions in a glass matrix, are the difficulty of integrating onto a single substrate and the need for high pump power densities to produce gain 1 .…”

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.

“…In this context, simple nitrophenolderived aromatics represent a potentially useful class of comparable chromophores [15]. Indeed poly-fluorinated nitrophenoxide ligands have been exploited in sensitized near-IR emitting species [16]. Substituted acetophenone chromophores with varying elements of charge-transfer character have also been employed to sensitise Eu III [17].…”

Dedicated to Prof. Jean-Claude Bünzli on the occasion of his 65th birthdayThe syntheses of the two tetraazamacrocyclic ligands L1 and L2 bearing a [(methoxy-2-nitrophenyl)amino]carbonyl chromophore, i.e., an N-(methoxy-2-nitrophenyl)acetamide moiety, together with their corresponding lanthanide-ion complexes are described. A combined spectroscopic (UV/VIS, 1 H-NMR), structural (X-ray), and theoretical (DFT) investigation revealed that the absorption properties of the chromophores were dictated by the extent of electronic delocalisation, which in turn was determined by the position of the MeO substituent at the aromatic ring. X-Ray crystallographic studies showed that when attached to the macrocycle, both isomeric forms of the N-(methoxy-2-nitrophenyl)acetamide unit can participate in coordination, via the C¼O, to an encapsulated potassium cation. Luminescence measurements confirmed that such a binding mode also exists in solution for the corresponding lanthanide complexes (q ca.1), with the para-MeO derivative allowing longer wavelength sensitization (l ex 330 nm).
