Luminescent Hybrids of Eu3+ Complexes Covalently Bonded with Mesoporous Silica and PMAA

Binary organic-inorganic mesoporous hybrid materials were prepared by covalntly grafting Lanthanide (III) (Eu) trifluoroacetylaceton (TAA) complexes to the ordered meosoporous silica SBA-15 via hydrothermal method and hydrolysis and co-polycondensation method with the surfactant P123 and TEOS. Besides, Novel ternary lanthanide (III) (Eu) organic-inorganic-polymeric mesoporous hybrid materials have been synthesized as well through the introduction of the organic polymer PMAA to the binary system with covalent bond. We investigated the thermal stability and luminescence properties of hybrids and found that the ternary hybrid materials exhibit better thermal stability and stronger emission intensity. Furthermore, compared with the binary mesoporous material Eu (TAA-SBA-15)3, the ternary mesoporous material Eu (TAA-SBA-15)3PMMA exhibits the characteristic emission of the Eu3+ ion with a higher luminescence Intensity, suggesting that the introduction of polymer PMMA into the mesoporous matrix is of benefit for the sensitization of Eu3+ luminescence, by replacing H2O groups that can quench the luminescence of Eu3+ ion.

The Eu

The organic ligand 2-Thenoyltrifluoroacetone (TTA) which was selected as molecular bridge for sensitization of europium and terbium ions were modified by 3-(triethoxysilyl)-propylisocyanate (TEPIC) to obtain the hybrid precursor TTA-Si. Then the solution of Eu(NO3)3 and Tb(NO3)3 were added in the presence of tetraethylorthosilicate (TEOS). The binary lanthanide organic/inorganic hybrid material were obtained. The ternary hybrid materials were obtained by adding the solution of Eu(NO3)3 and Tb(NO3)3 and Poly (ethylene glycol) (PEG400). We investigated the thermal stability and luminescence properties of hybrids and found that the ternary hybrid materials exhibit better thermal stability and stronger emission intensity. Furthermore, compared with the binary mesoporous material Eu-(TTA-Si)3 and Tb-(TTA-Si)3, the ternary mesoporous material Eu-(TTA-Si)3-PEG and Tb-(TTA-Si)3-PEG exhibits the characteristic emission of the Eu3+ and Tb3+ ion with a higher luminescence intensity, suggesting that the introduction of PEG is of benefit for the sensitization of Eu3+ and Tb3+ luminescence, by replacing H2O groups that can quench the luminescence of Eu3+ and Tb3+ ions.

Hybrid Precursor

The organic ligand sulfosalicylic acid (SSA) which was selected as molecular bridge for sensitization of terbium ions was modified by thionyl chloride (SOCl2) and 3-ammonium propyl triethoxy silane (APTES) to obtain the hybrid precursor SSA-Si. Then the solution of Tb (NO3)3was added in the presence of tetraethylorthosilicate (TEOS). The binary lanthanide organic/inorganic hybrid material was obtained. The ternary hybrid material was obtained by adding the solution of Tb (NO3)3and polyurethane. We investigated the thermal stability and luminescence properties of hybrids and found that the ternary hybrid materials exhibit better thermal stability and stronger emission intensity. Furthermore, compared with the binary mesoporous material Tb-(SSA-Si)3, the ternary mesoporous material Tb-(SSA-Si)3-PU exhibits the characteristic emission of the Tb3+ion with a higher luminescence intensity, suggesting that the introduction of polymer polyurethane into the mesoporous matrix is of benefit for the sensitization of Tb3+luminescence, by replacing H2O groups that can quench the luminescence of Tb3+ion.

Covalently Bonded

Triazolinediones (TADs) have been extensively used for the modification and crosslinking of polymers. However, there have not been any report on TAD bearing gels so far except an inorganic silica gel on which TAD is immobilized via ionic bonding. Here, I report a simple, scalable and general strategy to synthesize gels that contains covalently bonded TAD groups, starting from commercially available poly(hexamethylene diisocyanate). The covalently bonded TAD-gel platform could find many different applications such as the fabrication of hybrid materials, chemo-sensing, and scavenging excess reagents. In this work, potential scavenging application for TAD-gels were demonstrated with three different compound furan, aniline and limonene. Moreover, 1naphthol was selectively and completely removed from its mixture with 2-naphthol. The strategy developed here enables the preparation of poly(urea) and poly(ureathane) based novel materials via ultrafast modification at TAD moieties.
