DOI: 10.1016/j.polymer.2018.09.052

Abstract: Abstract A new pyrene-functionalized polytyrosine (pyrene-PTyr) by using l -tyrosine- N -carboxyanhydride as monomer synthesized through simple ring-opening polymerization with 1,6-diaminopyrene (pyrene-2NH 2 ) as the initiator. UV–Vis absorption spectra revealed that the absorption maxima… read more here.
