Most Efficient Tris(3-Aminopropyl) Amine Based Electron Deficient Tripodal Receptor for Azide
Journal of Fluorescence, 2020Co-Authors: Vanthana Jeyasingh, Kumaresan Murugesan, Sudha Lakshminarayanan, I. V. Muthu Vijayan Enoch, Narayanan Selvapalam, Lakshminarayanan PiramuthuAbstract:Investigation on strength of the tris(2-amino ethyl) amine and tris (3-amino propyl) amine backboned tripodal receptors, L and L ^ 1 (incorporated with tripodal C_3ν frame, thio urea-amide linkage and π-hole assisting functionality) which are premeditated to explore the prospect for a particular Anion recognition are studied. UV-Vis, ^1H- NMR, and IR spectroscopy studies indicates that both the receptors sensing Azide Anion, colorimetrically and binds Azide Anion stronger than any other Anions such as acetate, and cyanide. In particular the receptor L ^ 1 shows the highest binding strength towards Azide Anion. To the best of our knowledge this is the first receptor showing highest binding ability with Azide Anion. We used Molecular Electrostatic Potential Surface analyses to support our spectroscopic findings. The association constant and limits of detection for receptor L ^ 1 with Azide is found to be 8.4X10^5M^−1 and 3.16X10^−6 M respectively. The observed highest binding strength of L ^ 1 with Azide is, could be due to the cooperative effect of extended traditional hydrogen bonding via thiourea-amide functionality, Anion-π interaction and C_3ν suitable framework.

Selective colorimetric sensing and perfect linear recognition of Azide: Formation of Cu-Azide-Cu cascade complex within the cavity of cryptand.
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2020Co-Authors: Vanthana Jeyasingh, Kumaresan Murugesan, Sudha Lakshminarayanan, Narayanan Selvapalam, Geetha Das, Lakshminarayanan PiramuthuAbstract:Abstract Bis-trpn [tris(3-aminopropyl)amine], capped dicopper complex of bicyclic cryptand L, 1, became a potential selective colorimetric chemosensor for Azide Anion. Complex 1 is generating a space inside the cylindrical cavity which will be opt for perfect linear recognition of Azide Anion through as N4-Cu⋯N3−⋯Cu-N4 axle. Naked eye colorimetric and UV–Vis spectrometric investigations shows the complex 1 has the capability of selective sensing of Azide Anion. The association constant and limits of detection (LoD) of complex 1 towards Azide are found to be 2.754 × 103 M−1 and 1.91 × 10−6 M. To the best of our knowledge, this is the first example of selective colorimetric sensing of Azide by a bis‑copper cryptate 1 via ideal linear orientation of N4-Cu⋯N3⋯Cu-N4 axle inside the cylindrical shaped cavity.

Dalton Transactions, 2015Co-Authors: Liangliang ZhouAbstract:The Azide Anion as an energy acceptor and an electron donor has been introduced into a metal–viologen compound to form a 2D layered viologen-based trifunctional material, which exhibits the rare discolored function of reversible photochromism and thermochromism. Interestingly, its fluorescence can be switched by visible light irradiation and heating in air.
