DNA origami nanostructures (DOs) are promising tools for applications including drug delivery, biosensing, detecting biomolecules, and probing chromatin substructures. Targeting these nanodevices to mammalian cell nuclei could provide impactful approaches probing, visualizing, controlling biomolecular processes within live cells. We present an approach deliver DOs into live-cell nuclei. show that do not undergo detectable structural degradation in culture media or extracts 24 hours. To the...
It is recognized that metal organic complexes serve as sensitizers can present various degrees of challenges viz. synthesis and stability for photonic applications such triplet-triplet annihilation based photon upconversion (TTA-PUC). Presently, researchers, including our group, are turning their attention toward purely triplet sensitizers, which be handled more easily management science. In this review, we surveyed recently developed all-organic chromophoric systems were devised used...
PtBi$_2$ is a polymorphic system with interesting electronic properties. Here we report optimized crystal growth and structural characterization of pyrite-type trigonal modification PtBi$_2$. Selected area electron diffraction, X-ray powder diffraction further Rietveld refinement confirms that crystallizes in non-centrosymmetric $P31m$ space group, $Pa\bar{3}$ group. Series Pt$_{1-x}$Rh$_x$Bi$_2$ samples was obtained for $x=0, 0.03, 0.35$ the structure. These compounds become superconducting...
We report a novel reductive desulfurization reaction involving π-acidic naphthalene diimides (NDI) 1 using thionating agents such as Lawesson's reagent. Along with the expected thionated NDI derivatives 2–6, new heterocyclic naphtho-p-quinodimethane compounds 7 depicting broken/reduced symmetry were successfully isolated and fully characterized. Empirical studies theoretical modeling suggest that was formed via six-membered ring oxathiaphosphenine intermediate rather than usual four-membered...
A naphtho-p-quinodimethane (QDM) exhibiting Baird's 4n – π antiaromaticity was used as green photons-harvesting chromophore to sensitize perylene (Per) leading upconverted blue photoluminescence. The solution phase QDM → Per triplet energy transfer (TET) could not be unraveled via the Stern–Volmer method, but transient absorption measurements revealed that kinetics of T1 Tn for (τ = 1.4 μs) 1 order magnitude reduced 0.17 a result 3(Per)* formation. Furthermore, we demonstrated incident light...
DNA origami (DO) are promising tools for in vitro or vivo applications including drug delivery; biosensing, detecting biomolecules; and probing chromatin sub-structures. Targeting these nanodevices to mammalian cell nuclei could provide impactful approaches visualizing controlling important biological processes live cells. Here we present an approach deliver DO strucures into nuclei. We show that labelled DOs do not undergo detectable structural degradation culture media human extracts 24...
Since there have been many difficulties in clinical administration of anticancer drugs due to their poor solubility & targeting, development new biodegradable Nano-carriers can provide good solutions overcome the most recent problems obtain a better controlled release and targeted delivery with efficiency less side-effects. Acidic pH is regarded as phenotypic characteristic cancer tumors. Under this acidic condition, it known that surface charge Chitosan-modified nano-particles become more...
We report the synthesis and photophysical characterization of π‐expanded quinoidal triplet chromophores which exhibit attractive light‐harvesting properties. The kinetic excited state benzotetraphene 2 was found to be one order magnitude higher than lifetime 3 ( 1 )* from less conjugated parent chromophore . Furthermore, evaluation optoelectronic properties indicates that π‐expansion helps narrow band gap, but influence additional aromatic rings in structure compromises stability p...
The Cover Feature shows Lawesson reagent mediated selective transformations of pi-expanded acene diimides to afford the corresponding quinoidal triplet chromophores. comprehensive photophysics and aromaticity these chromophores were also described in present work. While pi-expansion strategy allowed create long-lived excited species, it was found that ring 2 3 would rearomatize produce persistent radicaloid derivatives.
