  • This module is intended to introduce you to the ideas and techniques of running a financially successful business. In order to grow and expand, businesses must both find profitable investments and obtain funds to make those investments. This module aims to give you the tools and skills you need to do those two things and to develop your understanding of the concepts and principles on which good financial decisions are based.

  • Platinum(II) Complex of Benzimidazole-Derived N-Heterocyclic Carbene: Synthesis, Characterization, and Photophysical Properties

    • Authors: Nguyen, Van Ha; Trieu, Thi Nguyet; Doan, Thanh Dat (2021)

  • Platinum(II) complex of benzimidazole-derived N-heterocyclic carbene with formula [PtCl2(DMSO)(bimy)] was successfully synthesized via one pot reaction between 1,3-diisopropyl benzimidazolium (bimy×HBr), Ag2O and [PtCl2(DMSO)] (DMSO = dimethyl sulfoxide). The complex was characterized by means of multinuclear (1H and 13C{1H}) magnetic resonance and single crystal X-ray diffraction (XRD). The UV-Vis absorption spectra of the compound show an absorption shoulder above 300 nm. Under excitation by 285 nm UV lamp, solution of the compound in DCM is highly emissive showing emission maxima at around 410 nm. DFT calculations were also carried out for the complex to gain insight on its electro...

  • Stereoelectronic Properties of 1,2,4-Triazole-Derived N-heterocyclic Carbenes - A Theoretical Study

    • Authors: Nguyen, Van Ha; Doan, Thanh Dat; Trieu, Thi Nguyet (2019)

  • A theoretical study on stereo and electronic properties of a series of six 1,2,4-triazole-derived carbenes bearing different N4-substituents, namely isopropyl (1), benzyl (2), phenyl (3), mesityl (4), 2,6-diisopropylphenyl (5) and 1-naphthyl (6), has been carried out. Structures of the six carbenes were first optimized using Gaussian® 16 at B3LYP level. Their molecular geometries and electronic structures of the frontier orbitals were examined. The results suggest the similarity in nature of their HOMOs, which all posses s symmetry with respect to the heterocycle and essentially be the lone electron pair on the Ccarbene. Steric properties of the NHCs was also quantified using percent ...
