DFT calculation studies were performed for the estimation of racemization barrier of winding vine-shaped heterobiaryls showing molecular asymmetry. The calculated value showed good agreement compared with that derived from experimental studies. Effects of hetroaromatic structure, carbon-carbon double bond at the winding-vine moiety, substituent at the double bond, and substituent at the heteroaromatic rings were studied.
