A 200°C difference in melting points has been observed for a derivative of o-tetraphenylene: Rajca, A.; Safronov, A.; Rajca, S.; Wongsriratanakul, J. J. Am. Chem. Soc. 2000, 122, 3351-3357. Although the enantiopure compound forms crystals containing aceto-nitrile guests, its melting behavior by differential scanning calorimetry is glasslike, with a glass transition temperature of about 213°C; the racemate has the usual crystallike melting point at about 430°C. In addition, the enantiopure compound readily forms isotropic films of good optical quality. Thus, this comparison of melting behavior is between enantiopure glass and racemic crystal: Andrzej Rajca, personal communication.

The stability differences were calculated from UV-visible absorbance by the equation ΔG = RT In K, with K = [(S)-VAPOL absorbance]/(rac-VAPOL absorbance). The free-energy difference was calculated for each of the three wavelength maxima, and these values were averaged to give the final free-energy difference.
