Incorporation of an azobenzene core into tethered bis(tritylalcohol) allows the photoswitchable arrangement of the two tritylalcohol units through photoisomerization of azobenzene. The differently arranged tritylalcohol units change their cooperative function to reflect the positional relationships, and thus, the activity as a cooperativeacid can be controlled by light stimuli (see figure).
