ABSTRACT:
The invention provides a device for selective molecular recognition, the device comprising a sensing portion, wherein said sensing portion includes a substrate having coated thereon a layer comprising a hyperbranched compound having:(1) a polymer backbone portion that is at least partly randomly branched;(2) at least one pendant group extending from the polymer backbone portion; and(3) at least one halogen substituted alcohol or phenol group substituted at the pendant group(s) of the polymer backbone portion.The compound of the invention preferably has the general formula:wherein A is the hyperbranched backbone portion of the polymer;L and M are independently selected pendant groups of said polymer backbone;X and Y are independently selected halogen substituted alcohol or phenol groups;q and r are independently selected and at least 1; andn is at least 3.The device is used to detect the molecules of a hydrogen bond accepting vapor such as organophosphorus or nitroaromatic species.
