This work aims to develop novel composites from a poly(L‐lactide‐co‐trimethylene carbonate‐co‐glycolide) (PLTG) terpolymer and mesoporous silica (SBA‐15) nanofillers surface modified by post‐synthetic functionalization. SBA‐15 first reacts with a silane coupling agent, γ‐aminopropyl‐trimethoxysilane to introduce ammonium group. PLLA chains were then grafted on the surface of SBA‐15 through ammonium initiated ring‐opening polymerization of L‐lactide. Composites were prepared via solution mixing of PLTG terpolymer and surface modified SBA‐15. The structures and properties of pure SBA‐15, γ‐aminopropyl‐trimethoxysilane modified SBA‐15 (H2N‐SBA‐15), PLLA modified SBA‐15 (PLLA‐NH‐SBA‐15), and PLTG/PLLA‐NH‐SBA‐15 composites were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, X‐ray diffraction, scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, transmission electron microscopy, N2 adsorption‐desorption, differential scanning calorimetry, contact angle measurement, and mechanical testing. The results demonstrated that PLLA chains were successfully grafted onto the surface of SBA‐15 with grafting amounts up to 16 wt.%. The PLTG/PLLA‐NH‐SBA‐15 composites exhibit good mechanical properties. The tensile strength, Young's modulus, and elongation at break of the composite containing 5 wt.% of PLLA‐NH‐SBA‐15 were 39.9 MPa, 1.3 GPa, and 273.6%, respectively, which were all higher than those of neat PLTG or of the composite containing 5 wt.% of pure SBA‐15. Cytocompatibility tests showed that the composites present very low cytotoxicity.

“…The organic polymer such as PVP [poly (vinyl pyridine)] [10], PEG [poly (ethylene glycol)] [11], PVPD [poly (vinylpyrroolidone)] [12], and PMMA [poly (methylmethacrylate)] [13][14][15] have been introduced into the organic/inorganic system to construct ternary organic/ inorganic/polymer hybrid materials. Among these organic polymers, PMMA is most commonly used polymer host due to its high flexibility, excellent optical properties and easy to fabricate and so on.…”

A novel ternary molecular hybrid material has been obtained by immobilization of Eu-Salen complex into silica matrix and poly (methyl methacrylate) (PMMA) matrix. Here, the Salen-type Schiff-base ligand H 2 Salen (N,N 0 -bis(salicylidene)ethylenediamine) which has been successfully modified by 3-(triethoxysilyl)-propyl isocyanate (TESPIC) has been used as a flexible linker and the antenna. The obtained solid hybrid material shows not only the characteristic red emission of Eu 3? but also the blue emission of Salen-Si host arising from the inefficient energy transfer from antenna to Eu 3? , leading to the unexpected near-white light color of the material. For comparison, the binary hybrid without PMMA has also been prepared. Photoluminescent spectra suggest that the introduction of PMMA can enhance the emission intensity whereas the chromaticity nearly has not been changed. Moreover, thermal analysis has revealed the good thermal stability of the ternary hybrid material. X-ray diffraction patterns demonstrate the amorphous structure of both hybrid materials.

“…Nowadays, the research interest on transition metal coordination polymers is increasing rapidly because of their potential applications in the areas of materials chemistry such as catalysis, nonlinear optics, electronics, photoluminescence, and adsorption [1][2][3][4][5][6][7][8][9]. It is well known that the construction of coordina tion polymers is mainly dependent on several factors such as the organic ligand, the geometric requirements of the metal atom, the temperature, the solvent system and the anion template effect etc.…”

A new one dimensional (1D) coordination polymer, [Cd(NPTA)(1,10 phen)(H 2 O)] n (1) (H 2 NPTA = 4 nitrophthalic acid; 1,10 phen = 1,10 phenanthroline monohydrate), has been synthesized under hydrothermal conditions and characterized by elemental analysis, single crystal X ray diffraction, solid state emission spectra, FT IR spectra, and thermogravimetric analyses. The compound belongs to tri clinic system with space group P , and exhibits a one dimensional linear chain. Each Cd with a strongly dis torted octahedral coordination geometry is six coordinated by two N atoms from one 1,10 phenanthroline ligand, three O atoms from two carboxylate groups of two different NPTA 2ligands and one O atoms from lattice water. Layer supramolecular architecture is formed by medium π-π stacking interactions between two neighboring phenanthroline rings from two independent linear chains. Studies on luminescent property of 1 exhibit the solid state emission originating from an intra ligand π → π* transition of NPTA 2ligand.
