The article conveys some information:
Polymeric supramol. nanorods were prepared in toluene by self-assembly of tris(urea) stickers connected on both sides through alkyl spacers of different lengths to short polystyrene (PS) arms. Several tris(urea) initiators or chain transfer agents were synthesized straightforwardly and used to grow well-defined PS arms via atom transfer radical polymerization (ATRP) or reversible addition fragmentation chain transfer (RAFT) polymerization Self-assembly was investigated by means of Fourier-transform IR (FTIR) spectroscopy and light/neutron scattering. A dramatic impact of the spacer separating the tris(urea) sticker from the PS arms on the extent of self-assembly was observed in toluene as long as the d.p. of the PS arms (x) was kept short (x ~10). Indeed, supramol. nanorods several hundreds of nanometers in length for a few nanometers in radius were obtained with a spacer consisting of nine atoms, whereas five times shorter nanorods were obtained for a spacer of only five atoms, and spherical particles were found in the absence of any spacer, all other parameters remaining unchanged. These results reveal the possibility to tune the length of polymer-decorated supramol. nanorods with minimal modification of the assembling sticker and without affecting the functionality of the rods. The experimental process involved the reaction of 6-Aminohexan-1-ol(cas: 4048-33-3HPLC of Formula: 4048-33-3)
6-Aminohexan-1-ol(cas: 4048-33-3) can undergo cyclization over copper supported on γ-alumina and magnesia to form hexahydro-1H-azepine. It may be used along with glutaric acid to generate poly(ester amide)s with excellent film- and fiber forming properties.HPLC of Formula: 4048-33-3
