High contrast mechanochromic and thermo chromic luminescence switching by a deep red emitting organic crystalIn this study, we report a deep red emissive organic crystal that displays high contrast fluorescence switching under mechanical- and thermal stimulation. Upon mechanical grinding, the pristine red emissive crystals of 1R (λem = 667 nm) transformed to green emissive crystalline powder (λem = 550 nm) with remarkable hypsochromic shift of wavelength, Dλ = 117 nm. Melting of 1R leads to green emissive […]

Flexible Electrochemical Transducer Platform for NeurotransmittersWe have designed a flexible electrochemical transducer film based on PEDOT−titania−poly(dimethylsiloxane) (PTS) for the simultaneous detection of neurotransmitters. PTS films were characterized using various techniques such as transmission electron microscopy, scanning electron microscopy, atomic force microscopy, four probe electrical conductivity, ac-impedance, and thermomechanical stability. The electrocatalytic behavior of the flexible PTS film toward the oxidation of neurotransmitters […]

Supramolecular Reassembly of Self ‐ Exfoliated Ionic Covalent Organic Nanosheets for Label ‐ Free Detection of Double ‐ Stranded DNAIonic covalent organic nanosheets (iCONs), a member of the two‐dimensional (2D) nanomaterials family, offer a unique functional platform for a wide range of applications. Herein, we explore the potential of an ethidium bromide (EB)‐based covalent organic framework (EB‐TFP) that self‐exfoliates in water resulting in 2D ionic covalent organic nanosheets (EB‐TFP‐iCONs) for the selective detection of […]

BF3•OEt2 Mediated Tandem Annulation: A Strategy to Construct Functionalized Chromeno-, and Pyrano- Fused PyridinesA simple and efficient one-pot annulation of arylidenones, alkynes, and nitriles in the presence of BF3.OEt2 is described. A highly functionalized variety of N-substituted pyridine fused-, chromeno and pyrano derivatives obtained with satisfactory yields under mild reaction conditions. The method was proven to be valid for the synthesis of the diverse library of chromeno [3,4-c]pyridines, […]

Epoxyazadiradione purified from the Azadirachta indica induced mitochondrial apoptosis and inhibition of NFκB nuclear translocation in human cervical cancer cellsEpoxyazadiradione (EAD) is an important limonoid present in Neem (Azadirachta indica) plant. In the present study, we have purified EAD from Neem seed and studied its anticancer potential in human cervical cancer (HeLa) cells. Cell proliferation inhibition studies indicated that the GI50 value of EAD is 7.5 ± 0.0092 μM in HeLa cells, whereas up […]
