Ultrafast recombination observed from several perylene imide sensitizers bound to NiO appears to align with Marcus normal region behaviour; this indicates recombination to intra-bandgap states.

Imide electrolyte salts have received increasing interest in lithium–sulfur battery (LSB) research due to their oxidation capacity, thermal stability, and cycling stability. Although the ionic conductivity of imide electrolytes is moderate, a LSB with exhibits improved charge–discharge (CD) capacity Coulombic efficiency. Here, we applied an effective strategy suppress polysulfide dissolution by...

Abstract Herein, we report on the design and synthesis of an N-annulated perylene butyl tetraester (PTEN-H) for use in alcohol processed semiconducting films. PTEN-H was contrasted with known diimide (PDIN-H) where former has ring-opened imide positions which turn lowers electron affinity (i.e. rendering hole transporting) improves polar green solvent solubility. can be solubilized 1-butanol up...

Solid polymer electrolytes, such as polyethylene oxide (PEO) based systems, have the potential to replace liquid electrolytes in secondary lithium batteries with flexible, safe, and mechanically robust designs. Previously reported PEO nanocomposite electrolytes routinely use metal oxide nanoparticles that are often 5-10 nm in diameter or larger. The mechanism of those oxide particle-based polym...

In the title mol-ecule, C16H14ClNO4, the four essentially planar atoms of the imide group [r.m.s. deviation = 0.0286 (11) Å] form a dihedral angle of 77.36 (13)° with the naphtho-quinone group [maximun deviation = 0.111 (2) Å for the carbonyl O atom in the naphthalene 1-position] and the two imide carbonyl groups are oriented anti with respect to each other. In the crystal, mol-ecules are conne...

20 new poly(ester-imide)s and poly(imide-urethane)s structures were synthesized using low temperature solution condensation polymerization. These compounds were optically active, capable of emitting circularly polarized light. The results indicated that the efficiency of the compounds much higher under this synthesis method. Cost effectiveness and short process were other advantages of this syn...

Perylene-imide derivatives are industrially important pigments that exhibit a variety of shades from red via maroon to black. In the present investigation, we have synthesized novel perylene-imide derivatives with pyridyl rings in an attempt to apply them for H2 gas sensors based on proton acceptors. The two N atoms of the pyridyl rings which work as proton acceptors are found to remain unbound...

The extraction of pertechnetate ions from aquous solutions containing various concentrations of nitric acid into hydrophobic ionic liquids (ILs) has been examined at 25, 50 and 70 °C. The results show that the distribution ratio of Tc (DTc) between both phases weakly depends on the temperature and HNO3 concentration when IL's with relatively short aliphatic chains are used. The DTc obtained for...

Two series of tricyclic inhibitors of the serine protease thrombin, imides (+/-)-1-(+/-)-8 and lactams (+/-)-9-(+/-)-13, were analysed to evaluate contributions of orthogonal multipolar interactions with the backbone C=O moiety of Asn98 to the free enthalpy of protein-ligand complexation. The lactam derivatives are much more potent and more selective inhibitors (K(i) values between 0.065 and 0....

The functional silica/polyamide-imide composite films were prepared via simple ultrasonic blending, after the silica nanoparticles were modified by cationic surfactant-cetyltrimethyl ammonium bromide (CTAB). The composite films were characterized by scanning electron microscope (SEM), thermo gravimetric analysis (TGA) and thermomechanical analysis (TMA). CTAB-modified silica nanoparticles were ...
