The amidine formed by tacrine and saccharin revisited: An ab initio Investigation of Structural, Electronic and Spectroscopic Properties

Year 2019, Volume: 3 Issue: 1, 25 - 37, 15.06.2019

Abstract

Computational study of tacrine and saccharin and their amidine complex (TacSac)
was peformed by ab initio calculations including electron correlation.
Structure, UV-Vis spectra and charge distribution of the amidine (TacSac) were
investigated using ground state geometries optimized at MP2/6-311++G(d,p)
level. The effects of solvent was investigated using polarizable continuum
model (PCM) in conjunction with the solvation model based on density (SMD)
approach. TacSac geometry remained same in gas phase and in H2O both
with PCM and SMD models in contrast to former DFT results. The amidine is calculated
to be stable indicating that former DFT calculations underestimated the
stability of the investigated amidine. UV-Vis spectra and electronic
transitions were calculated at CIS/6-311++G(d,p), B3LYP/6-311++G(d,p) and
CAM-B3LYP/6-311++G(d,p) levels of theory and B3LYP gave the best results.
TacSac has a peak at a higher wavelength enabling S0→S1
transition with a lower energy. S0→S1 transition
corresponds to full charge transfer between HOMO and LUMO orbitals of TacSac in
H2O. The ab initio results indicate that the TacSac system can be
synthesized with an easy condensation reaction, and that the amidine product is
a potential candidate for photochemical charge-transfer systems.
