Accurate chiral pattern recognition for amines from just a single chemosensor

Abstract

The current work proposes a novel method for accurate pattern recognition of (mono- and di-) amines and determination of enantiomeric excess (ee) using molecular self-assembly.

Enantioselective Fluorescent Recognition of β‐Amino Alcohols by Stereoselective Cyclization

“…Previously, a 1,1’‐binaphthyl‐based monoaldehyde ( S )‐ A in combination with Zn 2+ was found to show enantioselective fluorescence enhancement in the presence of chiral β‐amino alcohols [8g,h] . Without coordination of Zn 2+ , ( S )‐ A cannot form a rigid cyclic structure like 4 with an amino alcohol, and thus cannot give fluorescence enhancement.…”

Extended-gate-type Organic Field-effect Transistors for the Detection of Potential Psychological Stress Markers

“…(2) Detection accuracy should be considered from the viewpoint of stress diagnosis. Although OFET-based sensors show selectivity for target analytes due to the molecular recognition materials on the extended gate, pattern recognition (68) combined with multiple measurements with the OFET sensor array would be effective to enhance the detection accuracy.…”

Rapid chiral analysis based on liquid-phase cyclic chemiluminescence

“…18,19 However, these methods are time-consuming and technically complex, and the instrumentation required is expensive and bulky and requires well-trained operators. 20,21 Optical sensing methodologies, such as circular dichroism, [22][23][24] uorescence 25,26 and colorimetry, 27 have attracted considerable research interest as a result of their advantages of rapidity, simplicity, and low cost. In such a strategy, molecules or materials containing the chiral unit are used as chemosensory hosts that can interact with the chiral targets and then induce distinguishable optical signals.…”
