Novel Class of Isoxazole-Based Gelators for the Separation of Bisphenol A from Water and Cleanup of Oil Spills

Abstract

A series of low-molecular-weight gelators based on an isoxazole backbone were synthesized, which showed robust and phase-selective gelation of a series of oils. Due to their excellent phase-selective and cogelation properties, they were employed for the separation of bisphenol and the recovery of oil spills from water. The driving force and morphology of these gels were characterized by spectroscopic and microscopic studies.

Forward Wound Closure with Regenerated Silk Fibroin and Polylysine-Modified Chitosan Composite Bioadhesives as Dressings

“…Also, the difference between G' and G" values are diminished, implying a viscoelastic structure induced by the higher frequency at 25 °C. 51 The G′ and G″ values of the samples containing 100% w/v of water are the highest, reflecting the higher structural strength due to more chain winding or macromolecular connections. 52 The adhesive properties of the composite bioadhesives with various substrates are explored, and the results are given in (Figure 2a).…”

“…As the angular frequency increased, both of the values of G′ and G″ are clearly increased as well. Also, the difference between G’ and G” values are diminished, implying a viscoelastic structure induced by the higher frequency at 25 °C . The G′ and G″ values of the samples containing 100% w/v of water are the highest, reflecting the higher structural strength due to more chain winding or macromolecular connections .…”

Bio‐based polydimethylsiloxane porous sponge materials with programmable hydrophobicity and porosity for efficient separation of hydrophobic liquids from water

“…However, these procedures are associated with emission of particulate carbon soot, 22 CO 2 gas 29 and subsidiary environmental pollution 30 . The preferred way to address the above issues involves the use of organogels, 31 porous sponge materials 32 and hydrophobic polymers 33 to remove the oil through absorption 34 and subsequently collect the same for further use. Typically, the absorption capacity of the sponge, hydrophobicity, porosity, absorption‐desorption kinetics, surface area, durability, fabrication cost and selectivity play an important role in developing an effective absorbent for the above application.…”

Sugar isoxazole based hydrogelators and their applications as reusable hydrogels for dye removal

“…Several isoxazole based organogelators have been reported. [9][10][11] A few rigid aromatic isoxazoles have been shown to form organogels but not hydrogels. [12][13][14] Certain isoxazole based organogelators were studied for phase selective oil gelation for oil spill cleanup.…”

“…[12][13][14] Certain isoxazole based organogelators were studied for phase selective oil gelation for oil spill cleanup. 9,15 Isoxazoles have important biological activities and several glycosyl isoxazole conjugates have been synthesized due to their potential biological activities. [16][17][18] In the different applications of LMWGs, absorbing various dyes and drug molecules can have environmental applications.…”
