ENERGY STORAGE MOLECULAR MATERIAL, CRYSTAL DIELECTRIC LAYER AND CAPACITOR

The present disclosure provides an energy storage molecular material, crystal dielectric layer and capacitor which may solve a problem of the further increase of volumetric and mass density of reserved energy associated with some energy storage devices, and at the same time reduce cost of materials.

White-light emitting hydrogen-bonded supramolecular copolymers based on #-conjugated oligomers

Three different ?-conjugated oligomers (a blue-emitting oligofluorene, a green-emitting oligo(phenylene vinylene), and a red-emitting perylene bisimide) have been functionalized with self-complementary quadruple hydrogen bonding ureidopyrimidinone (UPy) units at both ends. The molecules self-assemble in solution and in the bulk, forming supramolecular polymers. When mixed together in solution, random noncovalent copolymers are formed that contain all three types of chromophores, resulting in energy transfer upon excitation of the oligofluorene energy donor. At a certain mixing ratio, a white emissive supramolecular polymer can be created in solution. In contrast to their unfunctionalized counterparts, bis-UPy-chromophores can easily be deposited as smooth thin films on surfaces by spin coating. No phase separation is observed in these films, and energy transfer is much more efficient than in solution, giving rise to white fluorescence at much lower ratios of energy acceptor to donor. Light emitting diodes based on these supramolecular polymers have been prepared from all three types of pure materials, yielding blue, green, and red devices, respectively. At appropriate mixing ratios of these three compounds, white electroluminescence is observed. This approach yields a toolbox of molecules that can be easily used to construct ?-conjugated supramolecular polymers with a variety of compositions, high solution viscosities, and tuneable emission colors.

Rigid oligoperylenediimide rods: Anion-π slides with photosynthetic activity

(Chemical Equation Presented) Slide rules: A new class of membrane-active rigid-rod molecules comprising π-acidic, n-semiconducting oligoperylene-diimides is introduced (see picture). They are able to combine passive anion transport across lipid bilayers with photoactive electron transport in the other direction across intact vesicle membranes. Thus, the compounds demonstrate artificial photosynthetic activity.

The present invention relates generally to the field of organic chemistry and particularly to the organic compound for organic photovoltaic devices. More specifically, the present invention is related to the organic compounds and the organic photovoltaic devices based on these compounds. In one preferred embodiment, this organic compound has the general structural formula (I) where Het1 is a predominantly planar polycyclic molecular system of first type; Het2 is a predominantly planar polycyclic molecular system of second type; A is a bridging group providing a lateral bond of the molecular system Het1 with the molecular system Het2 via strong chemical bonds; n is 1, 2, 3, 4, 5, 6, 7 or 8; B1 and B2 are binding groups; i is 0, 1, 2, 3, 4, 5, 6, 7 or 8; j is 0, 1, 2, 3, 4, 5, 6, 7 or 8; S1 and S2 are groups providing solubility of the organic compound; k is 0, 1, 2, 3, 4, 5, 6, 7 or 8; m is 0, 1, 2, 3, 4, 5, 6, 7 or 8; D1 and D2 are substituents independently selected from a list comprising -CH3, -C2H5, -NO2, -Cl, -Br, -F, - CF3, -CN, -OH, -OCH3, -OC2H5, -OCOCH3, -OCN, -SCN -NH2, -NHCOCH3, -C2Si(CH3)3, and -CONH2; y is 0, 1, 2, 3, 4, 5, 6, 7 or 8; and z is 0, 1, 2, 3, 4, 5, 6, 7 or 8.

A solution of the organic compound or its salt is capable of forming a solid photovoltaic layer on a substrate.

Self-assembly of supramolecular light-harvesting arrays from covalent multi-chromophore perylene-3,4:9,10=bis(dicarboximide) building blocks

We report on two multi-chromophore building blocks that self-assemble in solution and on surfaces into supramolecular light-harvesting arrays. Each building block is based on perylene-3,4:9,10-bis(dicarboximide) (PDI) chromophores. In one building block, N-phenyl PDI chromophores are attached at their para positions to both nitrogens and the 3 and 6 carbons of pyromellitimide to form a cross-shaped molecule (PI-PDI4). In the second building block, N-phenyl PDI chromophores are attached at their para positions to both nitrogens and the 1 and 7 carbons of a fifth PDI to produce a saddle-shaped molecule (PDI5). These molecules self-assemble into partially ordered dimeric structures (PI-PDI4)2 and (PDI5)2 in toluene and 2-methyltetrahydrofuran solutions with the PDI molecules approximately parallel to one another primarily due to π-π interactions between adjacent PDI chromophores. On hydrophobic surfaces, PDI5 grows into rod-shaped nanostructures of average length 130 nm as revealed by atomic force microscopy. Photoexcitation of these supramolecular dimers in solution gives direct evidence of strong π-π interactions between the excited PDI chromophore and other PDI molecules nearby based on the observed formation of an excimer-like state in 130 fs with a lifetime of about 20 ns. Multiple photoexcitations of the supramolecular dimers lead to fast singlet-singlet annihilation of the excimer-like state, which occurs with exciton hopping times of about 5 ps, which are comparable to those observed in photosynthetic light-harvesting proteins from green plants.

Making a Molecular Wire: Charge and Spin Transport through para-Phenylene Oligomers

Functional molecular wires are essential for the development of molecular electronics. Charge transport through molecules occurs primarily by means of two mechanisms, coherent superexchange and incoherent charge hopping. Rates of charge transport through
