“…First of all, we have a singlet at 1.30 ppm, which corresponds to the protons of CH 2 in the aliphatic chain of positions (4–5–6–7), and the multiplet at 1.60 ppm is assigned to CH 2 of positions (3–8); at 2.29 ppm, we have a triplet that corresponds to the CH 2 of positions (2–9). We also have a quadruplet at 2.6 and 2.9 ppm of the CH 2 protons of citric acid (a, b) as AB system 30,49,50 . The peaks at 3.31 and 4.91 ppm are those of the methanol solvent CD3OD and the physisorbed water H 2 O, respectively, due to the high hydrophilic character of these molecules; finally, we have the 9.2‐ppm peak that corresponds to the protons of the acid functions of citric acid, the peak is similar to that found by Vijayarajkumar et al 51 …”

The figure shows that there is no difference in both nanocomposites' spectra containing the CuNPs and obtained by conventional and sonication methods, this confirms that the synthesis method and the metal chosen have no impact on the functional groups of the molecule.…”

A new dendrimer based on citric acid and sebacoyl chloride was synthesized by Steglich esterification. The obtained dendrimer was used as a matrix for the dispersion of copper nanoparticles using classical and ultrasound methods. All materials were characterized by FTIR, 1H NMR, thermogravimetric analysis, X-ray photoelectron spectrometry, scanning electron microscopy, and energ-ydispersive -X-ray spectroscopy. The obtained nanocomposites were tested against two Gram-positive pathogenic bacteria (Bacillus cereus and Staphylococcus aureus), two Gram negative (Escherichia coli and Pseudomonas aeruginosa), the organic dye methylene blue, and in the 1,1-diphenyl-2-picrylhydrazile radical scavenging assay. A comparative study between both methods in structural, morphological, and thermal properties as well as in the antimicrobial, antioxidant, and catalytic reduction activities was provided. All nanocomposites showed an excellent activity for all applications. The comparison between both synthesis methods shows the superiority of the sonication methods, especially via the catalytic reduction and the antioxidant activities, the classic method allows better thermal stability and a higher metal content with some cationic oxidation state in the obtained nanocomposites, but ultrasound allows a better dispersion with a fully reduced metal.

“…Dendrimers are macromolecular with a highly branched structure that in their structure the branches emerge from one core 36–39 . These macromolecules could be synthesized via each of the traditional divergent or convergent approaches, as well as, recently the various advanced approaches have been provided for their synthesis 40–42 .…”

Nontoxic materials with natural origin are promising materials in the designing and preparation of the new drug delivery systems (DDSs). Today's, citric acid (CA) has attracted a great deal of attention because of its special features; green nature, biocompatibility, low price, biodegradability, and commercially available property. So, CA has been employed in the preparation of the various platforms to induce a suitable property on their structure. Recently, several research groups investigated the CA‐based platforms in different forms like tablets, dendrimers, hyperbranched polymers, (co)polymer, hydrogels, and nanoparticles as efficient DDSs. By considering an increasing amount of published articles in this field, for the first time, in this review, an overview of the published works regarding CA applications in the design of various DDSs is presented with a detailed and insightful discussion.

“…The discovery of ferrocene attracted the world due to its good reduction/oxidation features whereas it also provides thermal stability due to the strong interaction between the cyclopentadienyl ring and iron atom . This interaction helps towards the synthesis of different ferrocene‐based derivatives, polymers and dendrimers . Ferrocene as an individual compound with applications has already been well covered in the literature so in this section a very brief touch has been given for an idea.…”

Individually, ferrocene and photochromic materials have several important attributes and applications. Ferrocene is a promising candidate of stimuliresponsive materials due to its electronic, electrochemical and magnetic properties. On the same lines, photo-sensitive materials are also an important class of stimuli-responsive materials which can be modified according to the needs.Recently, a lot of keen attention has been given to the combination of ferrocene with different photo-sensitive moieties to get novel functional materials. This review illustrates the research advances in the combination of ferrocene-based small molecules, self-assembled monolayers and polymers with photo-responsive compounds and their potential applications.
