Garcia-Gonzalez, Ma. Carmen published the artcilePairing multicomponent stators with aromatic rotators for new emissive molecular rotors, SDS of cas: 18512-55-5, the publication is Organic & Biomolecular Chemistry (2021), 19(15), 3404-3412, database is CAplus and MEDLINE.
We demonstrate here that the Ugi-Sonogashira protocol can be successfully used to obtain five new mol. rotors such as I with strong emission. The mol. rotors have been synthesized by combining multicomponent stators derived from Ugi reactions of 4-iodoaniline, trans-cinnamaldehyde, 2-bromobenzoic acid, and cyclohexyl or tert-Bu isonitriles with dialkyne axles with phenylene, p-xylene, naphthalene and anthracene linkers. The synthesized conjugated rotors are highly fluorescent (Φf = 0.39 to Φf = 0.10), and changes in their emission were observed upon variations of the surrounding media, particularly on changes in solvents leading to aggregation or on increases in solvent viscosity.
