The determination of absolute configuration and enantiomeric excess of chiral compounds is a developing field with potentially broad applications. It is crucial to decide on the rapid and accurate absolute configuration of chiral primary amines, which have especially wide application areas. Therefore, there is a high demand for absolute configuration determination and enantiomeric excess of chiral compounds using Circular Dichroism spectroscopy. In this study, chiral organic compounds, named as diaminodicyanoquinodimethane, starting from tetracyanoquinodimethane as chromophore groups, were synthesized. Enantiomers of primary amine derivatives were used as chiral core units. The photophysical properties of the characterized chiral compounds were studied in methanol and tetrahydrofuran using UV-Vis and fluorescence spectroscopy. The interaction of chiral compounds with polarized light was studied using CD spectroscopy in methanol. Studies can be extended with different chiral amine derivatives.
