Multi‐Channel Receptors and Their Relation to Guest Chemosensing and Reconfigurable Molecular Logic Gates

Abstract

The synthesis and characterisation of a family of multi-channel receptors containing crown-cation binding sites anchored to a 1-aminophenyl-1,2,2-tricyanoethylene group is reported. The ligands L 1 -L 6 bear a 1-aminophenyl-1,2,2-tricyanoethylene scaffolding which is simultaneously a redox-active group (showing reduction processes at moderately modest potentials) and an acceptor moiety in the 1-aminophenyl-1,2,2-tricyanoethylene chromophore.

Control of Noise in Chemical and Biochemical Information Processing

“…Reversibility, [120,121] reconfigurability [122][123][124][125] and resettability [126,127] of the resulting gates have been explored. Digital logic functions of several-gate device components [128][129][130][131][132][133][134] have been realized, such as keypad lock and memory units.…”

Wireless radio frequency detection of greatly simplified polymeric membranes based on a multifunctional ionic liquid

“…The development of new sensing materials seems to be based on the use of single molecular probes capable of simultaneous determination of multianalytes [5,6], and also on simultaneous detection via multiple detection channels inherent to the material studied [7][8][9].…”

50 & 100 Years Ago

“…The three channels mentioned above have previously been used together in various combinations 5 , but Schmittel and Lin 1 now cleverly build on this foundation by adding the rarely used sensory technique of electrogenerated chemiluminescence 6 . This detects light emission from molecules following their electrochemical oxidation or reduction, and is therefore conceptually related to the other three methods.…”

“…Schmittel and Lin's work belongs to the field of multi-mode transducers 5 , molecular devices that convert chemical 'signals' into several other forms. An associated hot topic of research is the burgeoning area of array-based sensors, in which several molecular sensors are positioned on a single chip 12 or on the tip of an imaging fibre-optic 13 .…”
