Iron(iii) xanthate single-source precursors [Fe(S2COR)3] (R = methyl, ethyl, isopropyl and 1-propyl) were used to deposit iron sulfide thin films and nanostructures by two simple, efficient and low-cost methods (spin coating and solid state deposition). The single-crystal X-ray structures of the iron(iii) n-propyl xanthate and iron(iii) iso-propyl xanthate have been determined. Thermogravimetric analysis (TGA) studies of the complexes shows that decomposition of the complexes produces iron sulfide, pyrite or trolite. The crystallinity of iron sulfide thin films and powder samples was studied using X-ray diffraction (XRD), and their morphology was studied by scanning electron microscopy (SEM).

Four In(III) xanthate complexes, [In(S2COR)3] where R = Me, Et, iPr and sBu, respectively, were synthesized, characterized and subsequently used as single source molecular precursors via a solventless thermolysis route to obtain indium sulfide materials. By choice of precursor and reaction temperature crystalline powders of tetragonal In2S3, cubic In2S3 and cubic In2.77S4 were acquired. The phase identification and purity were conducted through examination of the experimental powder X-ray diffraction patterns relative to the simulated patterns for single X-ray crystal diffraction.
Improved synthesis of the high-mobility organic semiconductor dithiophene-tetrathiafulvalene
Crivillers, Nuria,Oxtoby, Neil S.,Mas-Torrent, Marta,Veciana, Jaume,Rovira, Concepcio
, p. 1621 - 1623 (2007)
Dithiophene-tetrathiafulvalene (DT-TTF) has been shown to be a promising organic semiconductor for organic transistors, since it combines high mobility with processability. A novel synthesis to prepare this material is described here. It involves the coupling of a 1,3-dithiol-2-one. The yield of this route is higher than previously reported yields.

Synthesis, Spectroscopy, Semi-empirical and Biological Activities of Organotin(IV) Complexes with o-Isopropyl Carbonodithioic Acid

New organotin(IV) complexes have been synthesized by treating potassium o-isopropyl carbonodithioate with R2SnCl2/R3SnCl in 1:2/1:1 M/L ratio. All complexes have been characterized by IR and NMR (1H, 13C) spectroscopy. IR results shows that ligand acts as bidentate which is also confirmed by semi-empirical study. NMR data reveals four coordinated geometry in solution. Computed positive heat of formation shows that complex 5 is thermodynamically unstable. UV/visible spectroscopy was used to assess the mode of interaction and binding of the complexes with DNA which shows that complex 5 exhibits higher binding constant as compared to complex 3. In protein kinase inhibition assay, compound 3 was found most active, while other biological activities shows that triorganotin(IV) complexes are biologically more active as compared to diorganotin(IV) complexes.
On the phase control of CuInS2 nanoparticles from Cu-/In-xanthates
Al-Shakban, Mundher,Matthews, Peter D.,Zhong, Xiang L.,Vitorica-Yrezabal, Inigo,Raftery, James,Lewis, David J.,O'Brien, Paul
, p. 5304 - 5309 (2018)
In this paper we report the synthesis and single-crystal X-ray characterisation of six novel indium(iii) xanthate complexes. These xanthates have been used as an In-source for the synthesis of highly crystalline CuInS2 nanoparticles in conjunction with a Cu(i)-xanthate. In synthesising the nanoparticles we have also demonstrated an ability to control the phase of the material through choice of solvent.
Tripodal pyrrolotetrathiafulvalene receptors for recognition of electron-deficient molecular guests
Watat, Michèle-Laure Lieunang,Dülcks, Thomas,Kemken, Dorit,Azov, Vladimir A.
, p. 741 - 744 (2014)
We report the synthesis of tripodal receptors with monopyrrolo- tetrathiafulvalene arms 1a,b, based on 1,3,5-substituted 2,4,6-triethylbenzene scaffold. The three converging pyrrolotetrathiafulvalene groups form an electron rich cone-shaped binding site. Molecular hosts 1a,b are capable of binding neutral electron deficient guests in solution, as well as positively charged pyridinium species in the gas phase.

An approach for the lower rim modification of the calix[4]arene-based molecular tweezes with monopyrrolo-tetrathiafulvalene (MPTTF) arms attached to the upper rim of calixarenes is described. First, calixarene-MPTTF conjugates with free hydroxyl on the lower rim are synthesized using the Ullmann reaction, then hydroxyl groups are substituted by propargyl groups, which can be used for further modification by the click reaction. The new calixarene-TTF derivatives displayed reversible redox processes, as well as demonstrated binding affinity for electron-deficient molecular guests such as tetracyanoquinodimethane. The described synthetic approach will be used for the modular synthesis of molecular receptors tailored for specific applications.
