Preparation of photocyclizable dianthracene derivatives of resorc[4]arenes which are potential photoswitches.
Resorc[4]arenes have been difunctionalized on opposite sides of the macrocycle using two anthracene units, which undergo intramolecular dimerization on irradiation at 350 nm. Syntheses and time-dependent photochemical experiments are reported.
