Product Introduction
4-Ethynylaniline, also known as p-ethynylaniline, is a terminal alkyne. Its synthesis using 2-methyl-3-butyn-2-ol (MEBYNOL) has been reported. The transition metal catalyzed polymerization of 4-ethynylaniline to afford poly(4-ethynylaniline) has been reported. The impact of the surface functionalization with 4-ethynylaniline on the thermal behavior of multi-walled carbon nanotubes (MWNTs) and graphene has been investigated.
