Photoinduced electron-transfer (PET)
reactions represent a powerful
methodology with widespread applications in the fields of organic
and synthetic polymer chemistry. Within this literature, among the
various surface coating methods, marine mussel-inspired adhesive bonding
by polydopamine (PDA) coatings has attracted great interest. Although
various procedures for PDA synthesis have been reported, they exhibit
some limitations, such as requirement of acidic or basic conditions
or strong oxidants. To address these issues, here we report a simple
PET protocol for PDA production under UV, visible, and daylight irradiation
using diphenyliodonium salt in the presence and absence of sensitizers.
This new methodology provides future directions for surface coatings
and bio-functionalization.
