Diketopyrrolopyrrole-based chemosensors for selective recognition of fluoride ions

Hydrazone-Based Small-Molecule Chemosensors

“…Among these designed chemoreceptors, p-NO 2 -DPPPH demonstrated selectivity for F − in UV-vis and fluorescence evaluations in DMSO solution. Additionally, experimental results of 1 H NMR and 19 F NMR revealed that the spectral changes occur due to deprotonation of the hydrazone N▬H moiety by fluoride ion [31].…”

Solid state structure and properties of phenyl diketopyrrolopyrrole derivatives

“…This behaviour opens up new potential applications for these materials as exciplex emitters in organic light emitting diodies, 46 in addition to their existing use as biological imaging agents in two photon fluorescence microscopy and optical analyte sensing applications. 1,[47][48][49][50][51][52][53][54][55] In this study, we investigate the solid state packing and optical properties of three families of PhDPPs (Fig. 1) that are distinguished by the nature of the N-substituent on the heterocycle, where it is either the n-hexyl chain (Hex), 56 branched (S)-2-methyl-butyl (2-MB) 23 or tert-butyloxycarbonyl (Boc) group.…”

Functional Sensing Materials Based on Lanthanide N-Heterocyclic Polycarboxylate Crystal Frameworks for Detecting Thiamines

“…Therefore, it is important to find a simple and practical method with high sensitivity, strong selectivity, and less reagents in the detection of concentration and composition analysis . The choice of sensor material is the most key part to get the effective detection. − Luminescent metal–organic coordination polymers are well explored as chemical sensor materials, because of their narrow spectral width, stable chemical structure, and long fluorescence lifetime, in applications such as detection of explosive nitroaromatics; ,,,− detection of metal cations; ,− detection of anions; ,− sensing of organic small molecules; ,,− sensing of solvent molecules; and so on. , …”
