is synthesized as sensitive material for nerve agents detection.Starting from dichlorosilane
2-(Bromomethyl)naphthalene
activated zinc and Allylbenzene
bis[phenpropyl]bis{2-naphthylmethyl}silane is synthesized by Grignard reaction
hydrosilylation reaction and Reformatsky reaction.The intermediate product is functionalized by hexafluoroacetone(HFIP)to produce the target material HPNMS.The sensitive material is evaluated as adsorbent coatings for nerve agent simulant DMMP on a SAW sensor.The result shows that the frequency shifts are linear to DMMP volume fraction in range of(30 ~170)×10-6 with a sensitivity of 266 Hz/10-6 for a thicker film.Fast response
fully desorption and good selectivity against acetone
