Facile Syntheses of 4-(2-Cyanoethylthio)-1,3-dithiole-2-thione and New Electron Donors with Two TTF Units and Compounds with Bis(1,3-dithiole-2-thione) Groups
from TBA 2 -[Zn(dmit) 2 ] were studied. Compound 1 was used to synthesize new electron donors with two tetrathiafulvalene (TTF) units. Other interesting compounds that are good precursors for tetrathiafulvalenophanes were also easily prepared from TBA 2 .[Zn(dmit) 2 ].

The cis isomer was converted to eight tetrathiafulvalene unit substituted magnesium porphyrazine upon a metal-templated cyclotetramerization with magnesium propoxide in propanol. The dicyanoethylenes and target compound were characterized by EA, NMR, and MALDI-TOF mass and photophysical and Electrochemicalproperties were discussed.
The synthesis and electrochemicalproperties of five novel organosulfur electron donors containing two to four TTF nuclei are reported. The structures have been assigned by 1H NMR spectroscopy, infrared spectrometry and mass spectra. Cyclic voltammetry (CV) studies show that the multi-TTFs display nearly ideal redox behavior for the TTF system with no distinct interaction between the TTF units.

hydrophobic stoppers at each end of the dumbbells. This modification was investigated as a means to simplify both molecular structure and switching function previously observed in related bistable [2]rotaxanes with flexible spacers between their stations and incorporating a cyclobis(paraquat-p-phenylene) (CBPQT4+) ring. The nondegenerate MPTTF-NP switch was isolated as near isomer-free bistable [2]rotaxane
A New Tetrathiafulvalene−Anthracence Dyad Fusion with the Crown Ether Group: Fluorescence Modulation with Na<sup>+</sup> and C<sub>60</sub>, Mimicking the Performance of an “AND” Logic Gate
In this Note, we describe a newTTF−anthracenedyad fusion with the crown ether unit. It is interesting to find that the fluorescence of this newdyad can be modulated with Na+ and C60, and its fluorescence intensity can be largely enhanced only in the presence of both Na+ and C60. Such fluorescence modulation behavior mimics the performance of a two-input “AND” logic gate.
