Needless to say, the development of green and sustainable reaction media instead of using volatile organic solvents as well as corrosive and/or expensive catalysts in the new millennium is continuously...
Truxene and its congeners due to its structural, thermal, and optoelectronic properties, has recently became important not only in biological systems but also in the field of material and environmental sciences. The remarkable scope and its applicability ranging from sensory materials to photocatalysts and fluorescent probes, forces the scientific community to think about the design and construction of architecturally simple yet much powerful novel functional materials possessing the truxene scaffold(s) in their structures. Herein, we have focused to assemble a series of ground‐breaking achievements in recent years of truxene‐based functional materials with special emphasis on their applicability in material sciences and technology. We hope that the present review will boost the current scenario of truxene and its various domains.
Rongalite, first time reported in the chemical structure in 1905, also known as bruggolite or sodium formaldehyde sulfoxylate, having good solubility and stability in organic media, is not only a cheap and commercially available (in kg amount) reagent with a range of industrial applications for instance emulsion polymerization, an excellent decolouring agent, antioxidant in pharmaceutical development, and an antidote for heavy metals, but also used as an effective regents in a plethora of organic reactions particularly in redox reactions as a powerful reducing agent. More interestingly, in recent years, it has also shown its impact in material sciences for the preparation of CdTe, CoTe2, and Ag2Se thin films, nanowire networks, hollow nanospheres, copper nanoparticles (Cu‐Nps), CdTe‐quantum dots and so forth. Keeping in mind the importance of this vital reagent in both organic chemistry as well as in material sciences, herein I intended to report the recent developments along with a brief overview of old literature wherever necessary to showcase the utility of this valuable reagent. This particular review article not only covers the applications of this environmentaly benign reagent in organic synthesis but also its usefulness in material sciences in particular nanosciences has been exposed for the first time.
This review lays emphasis on background concept and summarizes the recent developments of various competitive IDAs. Moreover, current challenges relating to the development of new IDAs and potential future perspectives revealing the fate of IDAs have also been given.
Facile access to
new one-walled
meso
-substituted
phenylboronic acid-functionalized calix[4]pyrrole (C4P) has been revealed
for the first time, starting from cost-effective and easily accessible
materials. The structures of both the intermediate dipyrromethane
(DPM) and the targeted functionalized C4P have been confirmed by means
of
1
H-NMR,
13
C-NMR, IR, and HRMS spectral data.
The voltammetric investigations of the functionalized C4P films cast
over a glassy carbon electrode (C4P-GCE) clearly establish the redox
stability and redox accessibility of the boronic acid functional moiety
present in the C4P framework. We demonstrate that the presence of
the unique boronic acid functionality in the C4P endows it with an
excellent potential for the highly sensitive electrochemical sensing
of the neurotransmitter dopamine (DA). A linear correlation between
the strength of the Faradaic signals corresponding to the electro-oxidation
of DA over C4P-GCE and the concentration of DA was observed in a concentration
range as wide as 0.165–2.302 μM. The C4P-GCE has revealed
exceptional stability and reproducibility in the electrochemical sensing
of DA, with a nanomolar level limit of detection as low as 15 nM.
