In the methodologies fluorescence based the use of analyte sensitive fluorophores
is a tool widely used in new technologies, since their properties can be modified
according to the molecular level design that is provided. One type of compounds of
interest are conjugated phenylene vinylidenequinolines, since their structure give a
wide electronic mobility, this characteristic give the property of fluorescing at
different wavelengths depending of repetition units that they contain. In this work
a tetramer was synthesized by means of the conventional reactions of Knovenagel,
Wittig and Heck coupling, which was chemically characterized by 1 H and 13 C NMR in
addition to FT-IR, a theoretical study was carried out where geometric optimization
was obtained to obtain the minimum energy structure using the Functional Theory
of Electronic Density (DFT) with Gaussian software 09W Version 7 and performing
the calculations with the hybrid density model b3lyp and a base set of medium size
6-31g (d ) in the gas phase, the energy values of the HOMO and LUMO border
orbitals were extracted and with the theoretical band gap of the molecule was
estimated, which was 2.81 eV, the optical characterization by absorbance and
luminescence was also obtained and the optical band gap of 2.9 eV and the
observed bandwidth of 106, this value positions the quinolinic compoundis in the
range of semiconductor materials. The results indicate that it will be use compound
as fluorophore.
