Switching of a Single Boryl Center in π‐Conjugated Photochromic Polyboryl Compounds and Its Impact on Fluorescence Quenching

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 un...

Description
Summary: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.
