摘要
All for one and one for all: Molecules with multiple conjugated photochromic boryl units undergo photoisomerization on a single boryl unit only. This single boryl switching causes fluorescence quenching of the entire molecule, which is greatly amplified with increasing numbers of switchable boryl units in the molecule. © 2010 WILEY-VCH Verlag GmbH & Co.
