Here in, we are reporting electron deficient amide and sulfonamide based tripodal receptors L, L, L and L. Systematic studies show a strong selectivity towards cyanide and azide anions. Detailed UV-Visible and fluorescent spectrometric investigation shows the amide based tripodal receptors L and L acts as a colorimetric and turn-on fluorescent chemo-sensor for cyanide, and the sulfonamide based tripodal receptors L and L acts as a colorimetric and turn-off fluorescent chemo-sensor for azide. At the end we have successfully prepared tripodal receptors for a particular anion with judicious choice of recognition elements such as hydrogen bonding amide/sulfonamide moiety, electron deficient pentafluorophenyl functionality for anion-π interaction and the well defined Cv symmetric tripodal backbone for perfect recognition.

Here in we report tris (3-aminopropyl) amine based tripodal receptors L, L and L which were functionalized with 4-nitrophenyl moieties having thio-urea, amide and sulfonamide as hydrogen bonding moiet...
The synthesis and characterisation of series of [Ru(II)(bpy)2L] and [Ir(ppy)2L] complexes containing ligands L with the potential to engage in triple hydrogen bonding interactions is described. L1 and...
In the present study, we demonstrated the effect of H-bonding in the semiconducting behaviour of a small molecule used in organic field-effect transistors (OFETs). For this study, a highly soluble dum...
Previous studies by Desiraju and co-workers have implicated the acidic hydrogen atoms of cubane as a support network for hydrogen-bonding groups. Herein we report a detailed structural analysis of all...
The design and preparation of organic two dimensional (O2D) sheets and their conversion to curved nanostructures is in its infancy. To convert a flat structure into a curved structure, the molecule mu...
This study is carried out to explore the short-term and long-term efficacy of the functional collagen scaffold in guiding laryngeal soft tissue regeneration.
The purpose of this study is to compare functional and anatomical results of a combined surgery and two time surgery for macular hole and cataract extraction in one hundred and twenty pati...
The purpose of this investigation is to assess the use of a novel scaffold (an FDA-approved collagen-hydroxyapatite material called Syn-Oss) for regeneration of pulp tissues versus the use...
To evaluate the correlations between anatomical and functional changes studied with microperimetry (MPM) and spectral-domain OCT (SD-OCT) in patients after successful repair of idiopathic ...
The study is designed to assess the safety and efficacy of functional neural regeneration collagen scaffold transplanted into acute spinal cord injury patients.
A low-energy attractive force between hydrogen and another element. It plays a major role in determining the properties of water, proteins, and other compounds.
Polymers of N-SUBSTITUTED GLYCINES containing chiral centers at the a-position of their side chains. These oligomers lack HYDROGEN BONDING donors, preventing formation of the usual intrachain hydrogen bonds but can form helices driven by the steric influence of chiral side chains.
The hardening or polymerization of bonding agents (DENTAL CEMENTS) via chemical reactions, usually involving two components. This type of dental bonding uses a self-cure or dual-cure system.
Stable elementary particles having the smallest known positive charge, found in the nuclei of all elements. The proton mass is less than that of a neutron. A proton is the nucleus of the light hydrogen atom, i.e., the hydrogen ion.
Pairing of purine and pyrimidine bases by HYDROGEN BONDING in double-stranded DNA or RNA.
