In this work, the optical properties of N,N-bis(aminobenzyl)naphthalenediimides 2a–2d (BzNDIs) and their interaction with fluoride were studied. The results demonstrated that the amino group position in the benzyl substituent exerts an effect in the absorption and emission properties. Particularly, the N,N-bis(2-aminobenzyl)NDI 2b presented non-typical absorption and emission bands which indicate an intramolecular charge transfer from the amino phenyl group to the NDI core. As the concentration of 2b increases, the solution turns from colourless to a pale orange colour. The interaction of BzNDIs 2a–2d with anions was selective towards fluoride and the affinity was in the order para?>?ortho?>?meta with respect to the position of the amino group in the aminophenyl ring. Interestingly, the colour change in the solution of 2b upon addition of fluoride makes it a good candidate for a fluoride colorimetric detection. The voltammetry analysis indicates the ability of these molecules to accept two electrons, in consequence the interaction of two fluoride anions with the BzNDIs was observed.

In early studies, we have reported the synthesis and biological activities of several cyclic imides. The present study describes the analgesic activity of 1,8-naphthalimide and 1,4,5,8-naphthalenediimide derivatives in a standard murine model of analgesia. The pharmacological results show that all compounds studied, given intraperitoneally, produced significant inhibition of acetic acid-induced abdominal constrictions. At the ID50 (μmol/kg) level, these cyclic imide derivatives were about 40-270- fold more potent in this assay than aspirin and acetaminophen, two well-known and widely used analgesics. These results extend previous studies on the analgesic activity of cyclic imides. (C) 2000 Elsevier Science S.A.

Paragraph 0183-0187, (2021/07/17)
The invention provides an organic small molecule electron transport material based on a naphthalimide unit and application thereof, belongs to the field of organic photoelectric materials, and solves the problems that in the prior art, the quantum dot light-emitting diode device is few in electron transport material selection and poor in device stability. The chemical structure of the organic small molecule electron transport material contains a naphthalimide unit, and the organic small molecule electron transport material has the advantages that 1) the lowest unoccupied molecular orbital energy level is low, electron injection and transport in a QLED device are facilitated, the highest occupied molecular orbital energy level is low, hole injection in the QLED device can be blocked, and the above two aspects are beneficial for improving the electroluminescent efficiency of the QLED device; (2) the absorption spectrum is mainly not located in a visible light region and does not absorb light emitted by the light-emitting layer in the QLED device; and 3) the material has a rigid configuration, can inhibit crystallization of the material, is beneficial to processing in a QLED, and is beneficial to improving the stability of a QLED device.
