摘要

The relative stability and accessibility of atropisomers plays a prominent role in the efficacy of diarylethene-based photochromic materials. Herein, DFT methods, using the omega B97XD functional and a 6-31G(d) basis, are employed to determine the local energetic minima and maxima which describe the rotation of a thiophene group in derivatives of 9,10-bis(2-methyl-5-pheylthiophen-3-yl) phenanthrene-2,7-dicarboxylic acid, a photochromic linker molecule which exhibits atropisomer-formation-related fatigue when incorporated into a metal-organic framework. Results of these potential energy surface mapping calculations as well as their applications to atropisomer separability are discussed.
