Tetrathiafulvalene (TTF) and its derivatives were originally prepared as strong electron-donor molecules for the development of electrically conducting materials. This Review emphasizes how TTF offer new in some cases little-exploited possibilities at molecular to supramolecular levels, well macromolecular aspects. is a well-established molecule whose interest goes beyond field materials chemistry be considered an important building block chemistry, crystal engineering, systems able operate...
An outstanding and selective material for Hg(<sc>ii</sc>) polluted water remediation based on an imine-linked COF endowed with triazole thiol groups.
Electroluminescence has been a subject of interest for several decades because its many applications in areas such as telecommunications or information displays. Light-emitting diodes using p-n junctions inorganic semiconductors have dominated the field last twenty years; however, efficient blue emission only recently achieved and are difficult to form over large areas, making process uneconomic. During decade, an explosive growth activity area organic electroluminescence occurred both...
Some of the current directions in research on new organic materials based functionalized oligoarylenes are reviewed. Particular emphasis is placed upon use chemical synthesis for incorporation suitable into more complex molecular and polymeric systems. Selected examples applications these different fields such as light-emitting diodes, photovoltaic devices, nonlinear optics, two-photon dyes, switches or ligands will be presented.
Molecular-wire behavior, that is, an exceptionally small attenuation factor (beta) of 0.01 +/- 0.005 A-1, has been established in novel C60-based donor-acceptor ensembles covalently connected through a series fully conjugated phenylenevinylene oligomers precise length and constitution.
We report herein an efficient, fast, and simple synthesis of imine-based covalent organic framework (COF) at room temperature (hereafter, RT-COF-1). RT-COF-1 shows a layered hexagonal structure exhibiting channels, is robust, porous to N2 CO2 . The room-temperature has enabled us fabricate position low-cost micro- submicropatterns on several surfaces, including solid SiO2 substrates flexible acetate paper, by using lithographically controlled wetting conventional ink-jet printing.
The synthesis, structural, electrochemical, and thin film electrical electronic structural properties of a series arylene diimide-oligothiophene n-type semiconductors are reported. This family compounds allows analysis the effects on transistor performance following: (i) oligothiophene backbone catenation; (ii) naphthalenediimide vs perylenediimide core interchange; (iii) phenylene group introduction in backbone. Electrochemical experiments indicate similar redox energetics for all members...

The main types of cyano-containing electron acceptor molecules, particularly those derived from TCNQ and DCNQI acceptors, have been reviewed. Ring substitution, the presence heteroatoms extendedπ-conjugation used as principal structural modifications on framework. Recent examples C 60 based acceptors bearing an organic addend other single-component donor–acceptor systems exhibiting semiconducting behaviour are also discussed.
In order to produce hydrogen peroxide in small-scale electrochemical plants, selective catalysts for the oxygen reduction reaction (ORR) toward desired species are required. Here, we report about synthesis, characterization, ORR behavior, and mechanism of an aza-fused π-conjugated microporous polymer, which presents high selectivity peroxide. It was synthesized by polycondensation 1,2,4,5-benzenetetramine tetrahydrochloride triquinoyl octahydrate. A cobalt-modified version material also...
A novel naphthalene diimide-based covalent organic framework (NDI-COF) has been synthesized and successfully exfoliated into COF nanosheets (CONs). Electrochemical measurements reveal that the diimide units incorporated NDI-CONs act as efficient electrocatalyst for oxygen reduction in alkaline media, showing its potential development of metal-free fuel cells.
The pyrolysis of organic precursors to produce heteroatomic-doped carbonaceous materials has emerged as a powerful tool construct metal-free heterogeneous electrocatalysts due their low cost and environmental friendliness. However, the lack control in atomic positions or location chemical functionalities makes it difficult establish structure–property relationships. Herein, we report an easy strategy compare electrocatalytic oxygen reduction reaction (ORR) performance nonpyrolyzed by...
In this study, we present a novel approach for the synthesis of covalent organic frameworks (COFs) that overcomes common limitations non-scalable solvothermal procedures. Our method allows room-temperature and scalable highly fluorinated DFTAPB-TFTA-COF, which exhibits intrinsic hydrophobicity. We used DFT-based calculations to elucidate role fluorine atoms in enhancing crystallinity material through corrugation effects, resulting maximized interlayer interactions, as disclosed both from...
Novel pi-conjugated donor-acceptor chromophores, based on the strong electron-donating tetrathiafulvalene moiety and different electron-withdrawing acceptors, exhibit large second-order optical nonlinearities. The effect of increasing length polyenic spacer influence nature acceptor NLO properties have been studied by using electric field-induced second-harmonic generation (EFISH) technique as well semiempirical ab initio theoretical calculations. A charge-transfer band has observed in...
Novel photo- and electroactive triads, in which pi-conjugated p-phenylenevinylene oligomers (oPPVs) of different length are connected to a photoexcited-state electron donor (i.e., zinc tetraphenylporphyrin) an acceptor C(60)), were designed, synthesized, tested as electron-transfer model systems. A detailed physicochemical investigation, concentrating mainly on long-range charge separation recombination kinetics, revealed small attenuation factors beta 0.03+/-0.005 A(-1). Energy matching...
A series of novel and soluble C60-(pi-conjugated oligomer) dyads were synthesized, starting from suitably functionalized oligomer precursors (i.e., dihexyloxynaphthalene, dihexyloxynaphthalene-thiophene, dihexyloxybenzene-thiophene). systematic change in the nature oligomeric component allowed (i) tailoring light absorption chromophore by shifting ground-state ultraviolet to visible region (ii) varying oxidation potential donor. The resulting electro- photoactive examined electrochemical...
Several generations of phenylenevinylene dendrons, covalently attached to a C(60) core, have been developed as synthetic model systems with hierarchical, fine-tuned architectures. End-capping these dendritic spacers dibutylaniline or dodecyloxynaphthalene, antennas/electron donors, yielded new donor-bridge-acceptor ensembles in which one, two, four donors are allocated at the peripheral positions well-defined while electron accepting fullerene is placed focal point dendron.
