- Abstract:
- ... In this report, a dipolar glass polymer, poly(2-(methylsulfonyl)ethyl methacrylate) (PMSEMA), was synthesized by free radical polymerization of the corresponding methacrylate monomer. Due to the large dipole moment (4.25 D) and small size of the side-chain sulfone groups, PMSEMA exhibited a strong γ transition at a temperature as low as −110 °C at 1 Hz, about 220 °C below its glass transition temp ...

- Abstract:
- ... HNO has recently been found to possess distinct biological functions from NO. Studying the biological functions of HNO calls for the development of sensitive and selective fluorescent probes. Herein, we designed and synthesized a FRET-based ratiometric probe to detect HNO in living cells. Our studies revealed that the probe is capable of detecting HNO in a rapid and ratiometric manner under physio ...

In this study, we have assessed the potential application of dichloro silicon phthalocyanine (Cl₂-SiPc) and dichloro germanium phthalocyanine (Cl₂-GePc) in modern planar heterojunction organic photovoltaic (PHJ OPV) devices. We have determined that Cl₂-SiPc can act as an electron donating material when paired with C₆₀ and that Cl₂-SiPc or Cl₂-GePc can also act as an electron acceptor material when ...

- ... With prominent photocatalytic applications and widespread use in semiconductor devices, TiO₂ is one of the most popular metal oxides. However, despite its popularity, it has yet to achieve its full potential due to a lack of effective methods for achieving p-type conductivity. Here, we show that undoped p-type TiO₂ films can be fabricated by atomic layer deposition (ALD) and that their electrical ...

A new type of bifunctional magnetic-fluorescent Fe₃O₄@SiO₂–PDI–PAA/Ca²⁺ nanoparticles has been prepared by coating PDI-cored star polymers (PDI–PAA) onto the surface of Fe₃O₄@SiO₂ core–shell nanostructures. The morphology and properties of the composite nanoparticles are investigated by transmission electron microscopy, ultraviolet–visible spectrometry, fluorescence spectrometry, and vibrating sam ...

Metal–organic frameworks (MOFs), such as MIL-125 (Ti), exhibit enhanced surface areas due to their high intrinsic microporosity, but the pore diameters of most microporous MOFs are often too small to allow for the diffusion of larger reactants (>7 Å) releva ...

In the efficient cosensitization, the pure organic sensitizers with high molecular extinction coefficients and long wavelength response are highly preferable since the dye loading amount for each dye in cosensitization is decreased with respect to single dye sensitization. A D-A-π-A featured quinoxaline organic sensitizer IQ21 is specifically designed. The high conjugation building block of 4H-cyc ...
