Spectroscopic characterizations on the N,N′-bis-alkyl derivatives of 1,4,6,8-naphthalenediimide charge-transfer complexes

Unravelling the molecular structure and packing of a planar molecule by combining nuclear magnetic resonance and scanning tunneling microscopy

“…[52][53][54] Additionally, infrared analysis of the product showed a band which is possibly due to an overtone vibration of the naphthalimide C-N, which does not appear in the reagents. 55 Other vibrational modes present in the IR spectra are assigned to the porphyrin reagent. 56 However, the naphthalimide modes overlap with the porphyrin modes, which makes the band assignment very difficult using this technique (see ESI †).…”

Electron Donor-Acceptor Interaction of 8-Hydroxyquinoline with Citric Acid in Different Solvents: Spectroscopic Studies

“…The formation of electron-donor acceptor (EDA) complexes can be rapidly assessed for its validity as a simple quantitative analytical method for many drug substances which can act as electron donors. Charge transfer complexes have been studied exclusively due to their wide application as ion sensors in the field of environmental science and in the determination of drugs based on the chargetransfer (CT) complexes formed with electron acceptors [3][4][5]. They also can be used as organic semiconductors photo catalysts, dendrimers, and in the studying of redox processes [6].…”

“…Recently, many studies have been widely reported about the rapid interactions between different kinds of drugs and related compounds as donors like morpholine, norfloxacin, ciprofloxacin, and sulfadoxine, with several types of andelectron acceptors [3,9]. Charge transfer interactions formed between 8-hydroxyquinoline and acceptors in different solvents has been studied spectrophotometrically [10].…”
