The analysis of natural and artificial chiral compounds is vital wherever the nuances in three-dimensional structure are decisive for possibility their further use, e.g., as pharmaceuticals or catalysts. qualitative determination a entity requires either an anomalous scattering X-ray radiation chiroptical techniques, which electronic circular dichroism (ECD) one most useful. Chiroptical sensing that uses stereodynamic probes remains remedies problem lack suitable chromophore molecules compound. A covalent non-covalent binding ECD-silent molecule (the inducer) to UV-active chromophoric system (chiroptical probe) led obtaining complex ECD active at given spectral region. transfer structural information from permanently inducer structurally labile probe results adjusting latter’s environment. This contribution focuses on some fundamental aspects chirality using conformationally probes. It discusses mechanism action arbitrarily chosen sensors, with particular emphasis based di- triarylmethyl derivatives biphenyl its congeners.
