A series of metal–organic frameworks (MOFs) M2(dobpdc) (M=Mn, Co, Ni, Zn; H4dobpdc=4,4′-dihydroxy-1,1′-biphenyl-3,3′-dicarboxylic acid), with a highly dense arrangement of open metal sites along hexagonal channels were prepared by microwave-...

We report here a tumor-targeting masked phototherapeutic agent 1 (PT-1). This system contains SN-38—a prodrug of the topoisomerase I inhibitor irinotecan. Topoisomerase I is a vital enzyme that controls DNA topology during replication, trans...

Fullerenes, cage-structured carbon allotropes, have been the subject of extensive research as new materials for diverse purposes. Yet, their formation process is still not clearly understood at the molecular level. In this study, we performe...

Achieving strong host–guest interactions between synthetic hosts and hydrophilic guests in solution is challenging because solvation effects overwhelm other effects. To resolve this issue, we transferred complexes of cucurbit[7]uril (CB[7]) ...

Amyloidosis is a clinical disorder implicated with the formation of toxic amyloid aggregates. Despite their pathological significance, it is challenging to define the structural characteristics of amyloid oligomers owing to their metastable ...

A well-organized donor–acceptor crystalline structure is examined for high ­performance nonfullerene solar cells. By thermal annealing, nanoscale structures of both donor and acceptor domains are successfully modulated, followed by ­signific...

The asymmetric total syntheses of deshydroxy-tetramethylcupressuflavone and desmethylkotanin and the synthesis of a key intermediate in the previous synthesis of hibarimicinone were described using an axially chiral biaryl boronic acid, prep...

Polydiacetylenes (PDAs) with thermochromic properties undergo colorimetric transitions when the external temperature is varied. This capability has the potential to enable these materials to be used as temperature sensors. These thermochromi...

Hollow Rh2S3 hexagonal nanoprisms, prepared by one-step formation of Cu1.94S@Rh2S3core-shell nanoprisms followed by the etching of core, exhibit very high catalytic activity and excellent stability toward hydrogen evolution reaction under ha...

We synthesized a highly crystalline DPP-based polymer, DPPBTSPE, which contained 1,2-bis(5-(thiophen-2-yl)selenophen-2-yl)ethene as a planar and rigid electron donating group. High- and low-molecular weight (MW) DPPBTSPE fractions were colle...

Mass spectrometry (MS)-based analysis using enzymatic digestion is widely used for protein sequencing and characterization. The large number of peptides generated from proteolysis, however, suppresses the signal of peptides with low ionizati...

Theranostics, chemical entities designed to combine therapeutic effects and imaging capability within one molecular system, have received considerable attention in recent years. Much of this interest reflects the promise inherent in personal...

The coexistence of intermixed amorphous polymer : fullerene phases alongside pure semicrystalline polymer and fullerene phases provides a plausible explanation for effective charge separation in organic photovoltaic blends by providing a cas...

Nature has endowed human beings with many useful functions, by virtue of supramolecular chemistry. As is well-known, nature can self-assemble relatively small molecular precursors into very complicated biomolecules. These supramolecular ense...

Catalytic properties of nanoparticles can be significantly enhanced by controlling nanoscale alloying and its structure. In this work, by using a facet-controlled Pt@Ni coreshell octahedron nanoparticle, we show that the nanoscale phase segr...

The development of fluorescent probes for the detection of biologically relevant species is a burgeoning topic in the field of supramolecular chemistry. A number of available dyes such as rhodamine, coumarin, fluorescein, and cyanine have be...

Mitochondria are organelles that are readily susceptible to temperature elevation. We selectively delivered a coumarin-based fluorescent iron oxide nanoparticle, Mito-CIO, to the mitochondria. Upon 740 nm laser irradiation, the intracellular...

A framework en-Mg2(dobpdc) (1-en; en = ethylenediamine) functionalized with the primary amine en was prepared via postmodification. From synchrotron PXRD data, it is revealed that the cell parameters change upon grafting of en and CO2 uptake...

A porous metal–organic framework (MOF), [Ni2(dobdc)(H2O)2]⋅6 H2O (Ni2(dobdc) or Ni-MOF-74; dobdc4−=2,5-dioxido-1,4-benzenedicarboxylate) with hexagonal channels was synthesized using a microwave-assisted solvothermal reaction. Soaking Ni2(do...
