CHEMOSELECTIVE DENDRIMERIC COMPOUNDS FOR USE IN CHEMICAL SENSORS

摘要

The present 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 dendrimeric compound having: (1) a core portion; (2) at least one unsaturated arms extending radially from the core portion; and (3) at least one halogen substituted alcohol or phenol group substituted at the terminus, the interior, or both of each; The device is used to detect the molecules of a hydrogen bond accepting vapor such as organophosphorus or nitroaromatic species.
