Object Of Study

ABSTRACTIn the last decades the interest in organic conductors has growth, so they have become the object of study of many research groups that are interested in developing new materials with important conducting properties. The charge transfer complexes (CTC) represent an important kind of organic conductors, because they exhibit high conductivity values, as well as versatility for their design.In this work, the charge transfer complex (CTC) formed by substituted pyrrole and tetrathiofulvalene (TTF) was obtained by means electrochemical synthesis, the resultant colored mix was characterized by Mass spectrometry, NMR and EPR studies, its intrinsic electronic behavior was measured by a four point probe method, besides theoretical calculations were carried out on the possible structures of the resultant molecular adduct. All the results show that there is a net transfer of an electron between both organic moieties in a solution giving place to a semiconductor species.

First Time

Quinolones are widely used, but there are few reports on the application of fluorescent probe analysis. In this paper, we synthesized a tricyano-dihydrofuran (DCDHF-2-V) electron acceptor, and a (DCDHF-2-V)-quinolone fluorescent nanoprobe was designed. Its structure was characterized by infrared spectroscopy (IR), nuclear magnetic resonance (NMR) and ultraviolet (UV). A novel tricyano-dihydrofuran-ofloxacin fluorescent nanoprobe was established for the first time by fluorescence spectrophotometry. A novel fluorescent nanoprobe was obtained and used in the determination of ofloxacin in vitro. The results showed that tricyano-dihydrofuran can form stable charge transfer complex with ofloxacin, and it can be used for the determination of ofloxacin in drugs as a fluorescent probe. While important experimental steps are for the first time achieved in this study for future Quinolone fluorescent nanoprobe implementations, this method is simple and sensitive.

Infrared Studies

The reactions of acetic, chloroacetic, and trichloroacetic acids with varying relative concentrations of pyridine in chloroform have been reinvestigated using infrared spectroscopy. The same Systems have also been studied in methanol. Some different assignments of peaks have been made, and the anomalous infrared results previously observed for trichloroacetic acid in chloroform are explained in terms of charge transfer complex formation.

Disorder Phase Transition

Fourier transform infrared spectroscopy was used to monitor the ∼200 K order-disorder phase transition of anthracene-h10: tetracyanobenzene and anthracene-d10:tetracyanobenzene charge transfer complexes. It was shown that the technique is sufficiently sensitive to monitor the temperature of transition and to study the transition via the infrared active internal vibrational modes.
