General description

Tetraethylenepentamine, also known as Tetrene, is a N5-structure polyamines ligand, often used as a nitrogen precursor to synthesize metal catalysts during oxygen reduction reaction (ORR).

Application

Tetraethylenepentamine (TEPA) can be used as a reagent:      
  • To functionalize magnesium 2,5-dihydroxyterephthalate (Mg-MOF-74) to enhance the CO2 adsorption performance of the material.
  • To modify magnetic chitosan resin to form amine-bearing chitosan for the efficient removal of uranium from an aqueous solution.
  • To synthesize poly(vinyl-chloride)/tetraethylenepentamine (PVC-TEPA) composite material, which is used as an efficient catalyst for the Knoevenagel condensation reaction.

Postsynthetic functionalization of magnesium 2,5-dihydroxyterephthalate (Mg-MOF-74) with tetraethylenepentamine (TEPA) resulted in improved CO2 adsorption performance under dry and humid conditions. XPS, elemental analysis, and neutron powder diffraction studies indicated that TEPA was incorporated throughout the MOF particle, although it coordinated

For the purpose of systemic delivery of siRNA, we previously developed polycation liposomes (PCLs) containing dicetylphosphate-tetraethylenepentamine (DCP-TEPA) as an effective siRNA carrier. In the present study, to endow these PCLs (TEPA-PCL) actively target cancer cells and angiogenic vessels, we decorated
