Abstract
In here, we investigated the required theoretical and experimental physical characteristics such as potential energy surface
scan, optimized structure, vibrational spectra, electronic band structure, molecular electrostatic potential surface, optical and
optoelectronic behaviors of the tris[4-(diethylamino)phenyl] amine (TDAPA) for different solvents (DMF and chloroform)
and techniques (experimental and theoretical). We obtained the significant, interesting, same and different results for them.
We obtained the refractive indices of the TDAPA for various conditions. The TDAPA exhibits a normal dispersion behavior
in visible region. TDAPA organic material is suitable for optoelectronic devices and applications such as metal–organic
semiconductor diodes due to the appropriate properties.
1 Introduction
Over the past decades, researchers and commercialized have
focused on the organic light emitting diodes (OLEDs). These
materials have a wide application in electrical, electronic,
optical, optoelectronic and photonic technology due to its
crystal structure, optoelectronic properties, panel displays
and lighting applications, easy conductivity control, good
environmental stability, corresponding to the visible spec-
trum, its energy gap of 2.5eV and low cost manufactur-
ing in large quantities [1–7]. Also these materials have high
contrast, low weight, flexibility and they can be rollable
or foldable to meet several special needs [8]. These wide
possible properties can be realized by analyzing the basic
science in involved in the operation the physics of OLEDs.
Triphenylamine (TPA) and related derivatives are widely
used as three-dimensional conjugated systems of organic
semiconductors (OSCs) with superior performance trans-
porting/hole-injecting behavior or luminophore materials in
LEDs due to the non-coplanarity geometry of the three phe-
nyl rings [9–11]. TPA-based compounds have been widely
applied as electroluminescence and hole transport materials
[10, 12–15] and their multifunctional and amorphous prop-
erties offer the possibilities to develop active materials for
organic fotovoltaic diodes and solar cells with charge trans-
port and isotropic optical properties [12]. On the other hand,
tris[4-(diethylamino)phenyl] amine (TDAPA) molecule is
used as a dopant of nanostructure film that it increasing car-
rier concentration [16].
In the present work, we investigated optoelectronic prop-
erties of TDAPA molecule for different solvents and molari-
ties. Also, the characterization of the TDAPA molecule was
theoretically performed by using the density function theory
(DFT) method, as well as in the use of the FT-IR, dispersive
Raman, UV–Vis measurements. Experimental and theoreti-
cal results were compared to better analysis. Investigation
of the spectroscopic and optoelectronic properties of the
TDAPA molecule is theoretically and experimentally impor-
tant for the formation of new OLED materials.
