Herein we report a novel fluoranthene-based fluorescent fluorophore 7,10-bis(4-bromophenyl)-8,9-bis[4-(hexyloxy)phenyl]fluoranthene (S(3)) and its remarkable properties in applications of explosive detection. The sensitivity towards the detection of nitroaromatics (NACs) was evaluated through fluorescence quenching in solution, vapor, and contact mode approaches. The contact mode approach using...

The recognition of the biologically and environmentally important ions is of great interest in the field of chemical sensors in recent years. The fluorescent sensors as a powerful optical analytical technique for the detection of low level of various analytes such as anions and metal cations have been progressively developed due to the simplicity, cost effective, and selectivity for monitoring ...

Many existing irrigation, industrial and chemical storage sites are currently introducing hazardous anions into groundwater, making the monitoring of such sites a high priority. Detecting and quantifying anions in water samples typically requires complex instrumentation, adding cost and delaying analysis. Here we address these challenges by development of an optical molecular method to detect a...

In recent years, there has been growing demand for wearable chemosensors for their important potential applications in mobile and electronic healthcare, patient self-assessment, human motion monitoring, and so on. Innovations in wearable chemosensors are revolutionizing the modern lifestyle, especially the involvement of both doctors and patients in the modern healthcare system. The facile inte...

A novel fluoranthene based fluorescent chemosensor for the detection of picric acid (PA) at the parts per billion (ppb) level was evaluated. Static fluorescence quenching was the dominant process by intercalative π-π interaction between fluoranthene (S(1)) and nitroaromatics.

A simple method for tuning the performance characteristics of fluorescent ratiometric sensors based on surface-immobilized monolayers of π-conjugated molecules enabled gradual adjustment of the sensitivity and the analyte detection range of the sensor. This approach has been applied to fine-tune the sensing performance of a prototype ratiometric chemosensor for fluoride ions.

This article summarizes the application of fluorescent sensors to in vitro diagnostic systems measuring critical care analytes in whole blood. We discuss recent advances in fluorescent chemosensor technologies employing fluorescence indicators used for this application. This paper touches on key materials, structure–property relations, and design considerations for maximum utility in low-cost p...

4-4'-Disubstituted biphenyl boronic acids (BBAs) are push-pull fluorophores with "turn-on" fluorescence properties. Upon carbohydrate triol binding, BBA boronate esters can participate in photon-induced electron transfer, giving a twisted intramolecular charge transfer (TICT) complex. The resulting TICT emissions distinguish between carbohydrates that bind to boron as a diol versus triol unit, ...
