Crime related to explosive and explosive related components are increasing rapidly. To combat the devastating effects of global terrorism, the detection of explosives and explosive-related materials is presently one of the most pressing global concerns. In recent years, significant progress has been made in the development of fluorescence-based chemical sensors for the recognition of explosives in the solid, solution, and vapor phases, with improved sensitivity, selectivity, and response speed. Quick, sensitive and selective detection of explosive is very much important in nowadays. In this paper, DPOC molecule is synthesized and characterize for detection of 1,3- dinitrobenzene. Detection limit is 7 µM. This method can be a good alternative for on-site detection of 1,3- dinitrobenzene at crime scene.

Globally, rapid, ultrasensitive, and ultraselective detection of forensic evidence is critically required for social security and support. In the past four decades, calixarenes have been the focus of intensive research in the invention of several extractants, transporters, stationary phases, electrode ionophores, and optical and electrochemical sensors. This review is ardent about calixarene, a new class of selective and sensitive forensic sensors. It has become clear that calix[n]arenes are particularly attractive building blocks for supramolecular chemistry due to their synthesis on a large scale, distinctive concave molecular architecture, tunable inner cavity size, exceptional derivatization capabilities, and a broad range of applications. This paper opens up new avenues for the creation of on-site detection kits for forensic evidence, which will speed up the detection procedure.
