Moreover, as discussed before, the molecule, with the SMILES of OC1CC1OC(C)C, is significant for drug application. Unfortunately, this molecule exhibits far-ultraviolet absorption and unlikely to be used in drug delivery applications. And we did not get useful analogues in databases. Herein, we propose the modification of the isopropyl by intruding double bonds (aldehyde, nitro etc.) can decrease the excitation energy, which can be used for Photoresponsive molecules with special drug values.
