“…55 The vacuum sublimation of monomeric triphenylene (55) formed 1D micro/nano crystalline fluorescence fibers, engendered detectable 80 fluorescence quenching upon exposed to saturated NB vapor while the saturated vapors of benzene, methanol, methylformate, acetone and nitromethane caused no quenching due to the lack of electron-withdrawing -NO 2 groups and aromatic rings. 56 Despite of detectable binding with NACs, the sensitivity of monomeric 85 triphenylene is less due to the low luminescent quantum efficiency. However, the quenching sensitivity can be improved by introducing suitable functional groups on the core triphenylene unit.…”

Selective and discriminative detection of -NO2 containing high energy organic compounds such as picric acid (PA), 2,4,6-trinitrotoluene (TNT) and dinitrotoluene (DNT) has become a challenging task due to concerns over national security, criminal investigations and environment protections. Among various known detection methods, fluorescence techniques have gained special attention in recent time. A wide variety of fluorescent chemosensors have been developed for nitroaromatic explosive detection. In this review article, we provide an overview of the recent developments made in small molecule-based turn-off fluorescent sensors for nitroaromatic explosives with special focus on organic and H-bonded supramolecular sensors. The fluorescent sensors discussed in this review are classified and organized according to their functionality and their recognition of nitroaromatics by fluorescence quenching.

Discotic liquid crystals (DLCs) are nanomaterials with sizes ranging from 2 to 6 nm, and they are emerging as one-dimensional organic semiconducting materials. Recently, hybridization of these materials with various metallic and semiconducting nanoparticles (NPs) to alter and improve their properties has been realized. This article provides an overview of the developments in the field of newly immersed discotic nanoscience, a sub-field of liquid crystal (LC) nanoscience. As this field is also of great interest to readers without an LCs background, a brief introduction of the LC field is given first, with special emphasis on DLCs. This is followed by various DLC-NP hybrid systems. Finally, an outlook into the future of this newly emerging, fascinating and exciting field of discotic nanoscience research is provided.
