Thus far, for the sake of simplicity, we have mostly focused on calculations of compounds with the nonfluorinated CP backbone, despite the F6CP fluorinated counterpart being found more commonly in the majority of the literature. In fact, the first study on a nonfluorinated dithienylcyclopentene photoswitch was published in 2002 by Duppen et al. Several works followed comparing the CP to the F6CP unit in photoswitches, with side groups based on substituted TPh. The main conclusion of this work was that the photoswitching properties of both series were very similar, with the nonfluorinated molecular switches having lower thermal and photochemical stability than the fluorinated analogs.
