Star-shaped thermosensitive poly-N-acyl-1,3-propylenimines with trianglamine core

Thermosensitivestar-shapedpoly-N-acyl-1,3-propylenimines with a macrocyclic trianglamine core were synthesized using a ‘grafting-on’ approach involving polymerization of 2-alkyl-5,6-dihydro-4H-oxazines at free trianglamine. The resulting polymers form complexes with europium ions and curcumin and can be used in the creation of delivery systems for drugs as well as contrast agents for NMR tomography.
