“…In contrast to conventional detection systems, such as those employing gas chromatographic − and electrochemical methods, − fluorescence probes utilizing small molecules have been investigated extensively and widely used due to their high sensitivity and selectivity, simple operations, and capabilities of real-time detection. − However, in contrast to those developed for detection of nerve agent mimics, − fluorescence probes for phosgene are limited, − and limitations exist in the use of some of those that have been developed thus far. For example, the selectivity of some of the reported probes for phosgene and nerve gas mimics has not yet been evaluated. − In addition, some of the previously developed phosgene fluorescence probes rely on the use of reaction groups that can be interfered with by formaldehyde and nitric oxide, − while others cannot discriminate between triphosgene and phosgene because they contain tertiary amine groups that catalyze the decomposition of triphosgene to phosgene .…”
