    Supramolecular Reassembly of Self ‐ Exfoliated Ionic Covalent Organic Nanosheets for Label ‐ Free Detection of Double ‐ Stranded DNA

    Ionic 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 […]

    High contrast mechanochromic and thermo chromic luminescence switching by a deep red emitting organic crystal

    In 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 […]

    Stepwise control of host–guest interaction using a coordination polymer gel

    Precise control of host–guest interaction as seen in biological processes is difficult to achieve with artificial systems. Herein we have exploited the thermodynamic benefits of a system in equilibrium to achieve controlled stepwise release and capture of cyclodextrin (guest) using a coordination polymer (Mg-CP) as the host and temperature as the stimulus. Since temperature is […]

    Germanium – incorporated lithium silicate composites as highly efficient low-temperature sorbents for CO2 capture

    Carbon dioxide emission from massive point sources such as industries and power plants is perceived to be a major contributor towards global warming and associated climate changes. Although lithium silicate has the highest capacity for CO2 sorption (8 mmol g−1), it is kinetically limited during the sorption process, particularly at temperatures below 500 °C. Herein, […]

    Musa paradisiaca inflorescence induces human colon cancer cell death by modulating cascades of transcriptional events

    Colorectal cancer (CRC) is one of the leading causes of cancer death with diet playing an important role in etiology of CRC. Traditional medical practitioners in many of the South Asian Countries use plantain inflorescence for the treatment of various gastro-intestinal ailments. The aim of the present study is to investigate the anticancer effect of […]

    BF3•OEt2 Mediated Tandem Annulation: A Strategy to Construct Functionalized Chromeno-, and Pyrano- Fused Pyridines

    A 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 cells

    Epoxyazadiradione (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 […]

    Self assembly of Oleylamine modified nano-fibrillated cellulose from areca husk fibers into giant vesicles

    Nanotechnology involving cellulosic substrates has generated a great attention owing to their exceptional physical and chemical properties. Self-assembled nanostructures obtained from carbohydrate polymers are of interest in the biomedical field for the biocompatibility and non-toxic nature. In the present study modification of nano-fibrillated cellulose (NFC) synthesized from the husk fibers of Areca catechu nuts (AHF) […]

    A Supramolecular Nanocomposite as a Near-Infrared Transmitting Optical Filter for Security and Forensic Applications

    Visibly opaque but near-infrared (NIR)-transparent materials are an essential component for night-vision photography, security imaging, and forensic applications. Herein, the development of a novel supramolecular black dye from a diketopyrrolopyrrole (DPP)-based low-molecular-weight organogelator is described. In the solution state, the monomer of DPP–Amide exhibits a deep green color with a broad absorption in the visible […]

    One-Pot MCR-Oxidation Approach toward Indole – Fused Heteroacenes

    A straightforward synthetic route toward indole-fused heteroacenes was developed. The strategy is composed of a one-pot process starting with a multicomponent reaction of cyclohexanone, primary amine and N-tosyl-3-nitroindole followed by an oxidation step. The one-pot approach was found to be general, affording both symmetric and nonsymmetric indolo[3,2-b]indoles in good yields. The strategy was also utilized […]
