All for one and one for all: Molecules with multiple conjugated photochromicboryl units undergo photoisomerization on a singleboryl unit only. This singleborylswitching causes fluorescencequenching of the entire molecule, which is greatly amplified with increasing numbers of switchableboryl units in the molecule.

Boron compounds having a conjugated chelate backbone (N,C-chelate or C,C-chelate) and two mesityl substituents on boron have been found to undergo a facile one-pot transformation/reaction with dienophiles, which leads to the dearomatization of one mesityl ring and its [4+2] Diels-Alder addition with the dienophile. Photochemical activation is the key in this transformation of the aryl ring.
