“…The third strategy is called chemosensing ensemble, based on a competitive assay in which a receptor-fluorophore ensemble is selectively dissociated by the addition of an appropriate competitive analyte able to interact efficiently with the receptor resulting in a detectable response of the fluorophore.

There is an enormous demand for chemical sensors for many areas and disciplines. High sensitivity and ease of operation are two main issues for sensor development. Fluorescence techniques can easily fulfill these requirements and therefore fluorescent-based sensors appear as one of the most promising candidates for chemical sensing. However, the development of sensors is not trivial; material science, molecular recognition and device implementation are some of the aspects that play a role in the design of sensors. The development of fluorescent sensing materials is increasingly captivating the attention of the scientists because its implementation as a truly sensory system is straightforward. This critical review shows the use of polymers, sol-gels, mesoporous materials, surfactant aggregates, quantum dots, and glass or gold surfaces, combined with different chemical approaches for the development of fluorescent sensing materials. Representative examples have been selected and they are commented here.

“…require significant changes of the electronic structure and thus are limited to ionic analytes. In the molecular recognition of neutral molecules execute a huge variety of developments [105][106][107][108][109][110]. Fluorescent chemosensors that rely exclusively on hydrogen bonding are reported as well [111][112][113][114][115][116][117][118][119].…”

“…Based on the intramolecular energy transfer, various fluorescent fluoride sensors have been synthesized. However, the linkage of the binding unit with a fluorophore through properly designed covalent bonds usually requires rather complicated multistep organic synthesis [21][22][23][24]. On the other hand, if a supramolecular sensor system is constructed through intermolecular energy transfer, the complicated organic synthesis could be avoided, and a wide range of well known fluorophores could be readily selected and utilized.…”

A novel fluorescence enhancing F− probe based on intermolecular energy transfer

et al. 2010

A supramolecular fluorescent sensor of F -based on intermolecular energy transfer is described. The maximum absorption wavelength of a pyrrolic compound 1 is 472 nm, which is coincident with the emission wavelength of a dipyridylamine-anthracene compound 2. In the CH 2 Cl 2 solution of 1 and 2, the fluorescence of 2 was quenched because of the presence of intermolecular energy transfer from 2 to 1. When F -was added to this solution, the absorption maximum wavelength of 1 shifted from 472 to 594 nm due to a deprotonation process. Simultaneously, the fluorescence of 2 was recovered because of the interruption of the intermolecular energy transfer. Based on these observations, the combination of 1 and 2 can be regarded as a novel supramolecular fluorescence enhancing F -probe.
