Abstract:
The mechanochromic luminescence phenomenon was first reported in the low-cost mechanochemical (MC) synthesis process of a covalent organic framework (COF-TpMA (MC)) prepared using triformylphloroglucinol (Tp) and melamine (MA) as precursors, which shows excellent performance as a hydroxyl radical (˙OH) detector in living systems. This work not only shows a new kind of mechanochromic luminescent material but also exhibits a close relationship between the π-π stacking and luminescence properties of COF materials.

Covalent Bonds
Covalent Bonds
When two atoms share electrons to complete their valence shells, they create a covalent bond. An atom's electronegativity—the force with which shared electrons are pulled towards an atom—determines how the electrons are shared. Molecules formed with covalent bonds can be either polar or nonpolar. Atoms with similar electronegativities form nonpolar covalent bonds; the electrons are shared equally. Atoms with different electronegativities share electrons unequally,...
