Coronene·TCNQ cocrystal microrods, coronene microrods, and TCNQ microsheets were constructed by a drop-casting method. Prototype devices were fabricated and their field-effect-transistor (FET) performances were investigated. It is found that coronene·TCNQ microrods had exhibited an n-type characteristic and showed better FET performances than TCNQ microsheets.

Electrodes prepared as compacted pellets from conductive donor-acceptor complexes of tetracyanoquinodimethane (TCNQ) with several donors (D) (tetrathiotetracene, acridine, quinoline, N-methylphenazine, 2,2'and 4,4'-bipyridine) were investigated in aqueous solutions. The results were compared to those of a previous investigation of TTF-TCNQ pellets (TTF = tetrathiafulvalene) and to results on si...

Donor-substituted 1,1,2,4,4-pentacyanobuta-1,3-dienes and a cyclohexa-2,5-diene-1,4-diylidene-expanded derivative were prepared by a [2 + 2] cycloaddition of tetracyanoethene (TCNE) or 7,7,8,8-tetracyanoquinodimethane (TCNQ) to anilino-substituted cyanoalkynes, followed by retro-electrocyclisation; they feature intense bathochromically-shifted intramolecular charge-transfer bands and undergo th...

The crystal structure of [Ni(bpy)3]2(TCNQ–TCNQ)(TCNQ)2·6H2O (1) was studied by X-ray single-crystal analysis at 145 K and 100 K. structures 1 these two temperatures are essentially the same as previously 200 K: is built up [Ni(bpy)3]2+ complex cations, centrosymmetric crystallographically independent TCNQ·- anion-radicals, disordered σ- π-dimerized (TCNQ)2 units, water molecules crystallization...

The current work reports the effect of palladium nanoparticles and their nanogeometry on redox electrochemistry tetracyanoquinodimethane (TCNQ) modified electrodes. Palladium were prepared with different concentrations 3-aminopropyltrimethoxysilane calcination at 600 °C to yield PdNP-1 PdNP-2 average size 1 µm 12 nm, respectively. characterized by TEM, XRD, AFM techniques. electrochemical excel...

The slow diffusion reaction of [Ru(2)(O(2)CCF(3))(4)(THF)(2)] with TCNQ in CH(2)Cl(2)/4-chlorotoluene, respectively, leads to the formation of ladder chain composed of [Ru(2)] rails and TCNQ rungs in a 2 : 1 ratio.

We report the first cocrystals of TCNQ and TCNB based on orthocetamol, a regioisomer paracetamol. Through simple solution growth process, were produced containing orthocetamol as electron donors with coformers either 7,7,8,8-tetracyanoquinodimethane (TCNQ) or 1,2,4,5-tetracyanobenzene (TCNB), acceptors. Because submicron crystalline domains, 3D diffraction was employed for structure in both sys...

The 3-D coordination polymer with the basic formula Cd2(TCNQ)3.5(H2O)2 is the first instance of the coexistence of the bridging modes μ2, μ3 and μ4 for TCNQ in one network. Single crystal measurements revealed the compound to be a good semiconductor with a room temperature conductivity of 5.8 × 10(-3) S cm(-1).

the purpose of this investigation was directed to propose sensitive, accurate and reproducible methods of analysis that can be applied to determine distigmine bromide (dtb), cyclopentolate hydrochloride (cphc), diaveridine hydrochloride (dvhc) and tetrahydrozoline hydrochloride (thhc) drugs in pure form and pharmaceutical preparations via charge-transfer complex formation with 7,7,8,8-tetracyan...
