DESCRIPTION:Although this seminar will be in person\, the seminar can be vi
 ewed online: https://mcgill.zoom.us/j/81771740265\n\nAbstract:\n\nFor the 
 past few years we have been developing structurally simple\, easy to make\
 , modular\, and tunable hydrazone-based functional materials (e.g.\, switc
 hes\, sensors and fluorophores).1 This presentation will deal with our rec
 ent advances with these systems\, with an emphasis on newly developed phot
 ochromic compounds2 that exhibit many interesting properties\, including e
 mission ON/OFF toggling in solution (see below) and the solid-state.3 The 
 integration of these photochromic compounds into liquid crystals4 and liqu
 id crystalline elastomers\,5 and their use in the templated-synthesis of g
 -cyclodextrin\,6 will also be discussed.\n\n \n\nRepresentative references

 Professor Aprahamian received all his degrees (BSc in 1998\, MS in 2000\, 
 and PhD in 2005) from the Hebrew University of Jerusalem\, Israel. His doc
 toral research focused on NMR spectroscopic studies of alkali metal reduce
 d polycyclic aromatic hydrocarbons. He then carried out postdoctoral resea
 rcher in Professor Sir Fraser Stoddart's group at UCLA\, where he focused 
 on the synthesis of switchable and highly-ordered interlocked molecules in
  the form of bistable [n]rotaxanes. Dr. Aprahamian joined the faculty at D
 artmouth College in August 2008\, and was promoted to Associate Professor 
 in 2014\, and Full Professor in 2019. His research group focuses on using 
 structurally simple\, modular\, and tunable hydrazone-based building block
 s in the development of adaptive functional materials\, including switches
 \, sensors and fluorophores. Dr. Aprahamian is the recipient of the 2016 C
 ram Pederson Lehn Award in Supramolecular Chemistry\, and is a Humboldt an
 d Royal Society of Chemistry Fellow.\n
