 bon-based polymers has shown to be an effective strategies to access new f
 unctional materials with applications in various areas of science and tech
 nology.1 To date\, metallopolymers incorporating about 30 different metals
  in combination with a wide range of ligands have been reported. Among the
  ligand component\, multi-dentate N-donors and cyclopentadiene moieties ha
 ve been widely used.1 However\, those based on N-heterocyclic carbenes (NH
 Cs) have been significantly underdeveloped. This is surprising because NHC
 s are known to form exceptionally strong bonds to a variety of transition 
 metals. In the realm of polymer chemistry\, only handful examples of NHC-m
 etal polymers exist.2\,3 Our group has recently started working in this ar
 ea to develop novel approaches to synthesize polymerized NHC-metal complex
 es and to utilize them as substrates to fabricate highly stable metal nano
 particles. In this presentation\, I will discuss some of the advances we h
 ave made in accessing such polymers and their corresponding nanomaterials.
  In addition\, the application of these metal nanoparticles as well as the
 ir stabilities will be presented.\n\n\n	[1] Yan\, Y.\; Zhang\, J.\; Ren\, L

 io:\n\nAli completed his B.Sc. in Chemistry from K. N. Toosi University of
  Technology (Iran) in 2005. He then moved to Canada and completed his M.Sc
 . in Inorganic Chemistry at the University of Toronto with Prof. Datong So
 ng (2009) and his Ph.D. at The University of Western Ontario with Prof. El
 izabeth R. Gillies (2013). After his graduate studies\, Ali first spent tw
 o years (2014−2016) in England as a Marie Curie Postdoctoral Research Fell
 ow with Prof. Ian Manners at the University of Bristol and then came back 
 to Canada at Queen’s University (2016−2017) to work with Prof. Cathleen M.
  Crudden as a postdoctoral fellow. In January 2018\, Ali started his indep
 endent career as an assistant professor at Université du Queb́ec à Montreá
 l. His group focuses on design\, synthesis\, and self-assembly of novel po
 lymeric and dendritic\n	systems to fabricate nanomaterials for applications
  in nanomedicine.\n
