Fentanyl is an anesthetic with a high bioavailability and is the leading cause of drug overdose death in the U. S. Fentanyl and its derivatives have a low LD and street drugs which contain such compounds may lead to death of the user and simultaneously pose hazards for first responders. Rapid identification methods of both known and emerging opioid fentanyl substances is crucial. In this effort, machine learning (ML) is applied in a systematic manner to identify fentanyl-related functional groups in such compounds based on their observed spectral properties. In our study, accurate IR (IR) spectra of common organic mols. which contain functional groups that are constituents of fentanyl is determined by investigating the structure-property relationship. The average accuracy rate of correctly identifying the functional groups of interest is 92.5% on our testing data. All the IR spectra of 632 organic mols. are from National Institute of Standards and Technol. (NIST) database as the training set and are assessed. Results from this work will provide Artificial Intelligence (AI) based tools and algorithms increased confidence, which serves as a basis to detect fentanyl and its derivatives The experimental procedure involved many compounds, such as 2-(1H-Benzo[d]imidazol-2-yl)aniline (cas: 5805-39-0) .

A quinazoline derivative 6-anthracenyl-5,6-2H-benzimidazo[1,2-c]quinazoline (L) was obtained and characterized by elemental anal., IR spectroscopy, ¹H NMR and single-crystal X-ray diffraction. L shows very weak emission in DMSO, but can respond to Hg²⁺ ion intensively in off-on mode. Job’s plot and titration experiments show that Hg²⁺ ion binds L in 1:1 stoichiometry. The detection limit for Hg²⁺ is 6.34μM. ¹H NMR titration experiments indicate that only one benzimidazo nitrogen atom coordinates with Hg2+. And the fluorescence emission spectra imply that an excimer formed in the Hg²⁺-L system, and the detection of Hg²⁺ was realized by excimer emission of anthracene moiety.

Reversible dual channel sensor F2 for detection Cu²⁺ is designed and synthesized. F2 is substantially unaffected by other cationic ions during the recognition of Cu²⁺. It is worth noting that the low detection limit of sensor F2 is 9.09 × 10^-9, and the detection limit is lower that to the reported sensor for identifying Cu²⁺. Through various experiments and characterization, it is proved that ligand-metal charge transfer (LMCT) is the interaction mechanism between F2 and Cu²⁺. It is further certified that the stoichiometry between F2 and Cu²⁺ is 1:1. In addition, the fluorescence changes of F2 upon the addition of Cu²⁺ and EDTA are applied as an ultrasensitive IMPLICATION logic gate at the mol. level. At the same time, mol. keyboard experiments have achieved information protection at the mol. level.

The compounds I have been characterized with spectroscopy and microanal. The crystal structures of triazatetracyclics I [R = Me, R¹ = Me (II); R = Et, R¹ = Me (III); and R = Ph, R¹ = H (IV)] have been discussed. The computed NMR, IR, mol. electrostatic potential and frontier MOs of compounds II, III and IV have been discussed.
