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.

The Eu

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.
