“…Polymer brushes are surface-tethered macromolecules that can be engineered via a broad range of surface-initiated polymerizations (SI-Ps). , Beginning with seminal reports on the utility of photons in SI-Ps, various light-mediated surface-initiated (SI) reversible deactivation radical polymerization (RDRP) approaches have been established and advanced. This includes light-mediated, SI atom transfer radical polymerization (SI-ATRP), − SI nitroxide mediated polymerization (SI-NMP), − SI photoiniferter mediated polymerization (SI-PMP), − SI thiol- methacrylate photopolymerizations, and SI photoinduced electron transfer-reversible addition–fragmentation chain transfer polymerization (SI-PET-RAFT). − Many of these chemistries can now be mediated from ultraviolet (UV) to near-infrared (IR) wavelengths, − with tolerance to ambient oxygen, and used for complex topographical patterning. − …”

Polymer brushes offer a wide array of applications in surface modification. While recent advances have made these chemistries more userfriendly, scientific questions about fundamental polymer properties often remain unanswered. For example, copolymer brush composition, chain end fidelity, and dispersity often remain prohibitively challenging to characterize. This conundrum produces a need for chemically precise pathways to evaluate polymer brushes. To this end, this contribution describes the synthesis of an o-nitrobenzyl-based photolabile initiator for surface-initiated reversible deactivation radical polymerization. The product can be immobilized on surfaces, enable growth of polymer brushes under visible light, and be cleaved under ultraviolet (UV) irradiation. Wavelength selectivity is confirmed using a combination of ellipsometry, tensiometry, and X-ray photoelectron spectroscopy, and patterning experiments indicate good spatial control over photocleaving. Finally, nuclear magnetic resonance spectroscopy indicates visibility of characteristic peaks for both chain ends after degrafting of the polymer brush.

Surface‐grafted polymer brushes (PBs) are a versatile class of thin coatings that exhibit unique properties due to their densely grafted polymer chains. PBs are typically formed through surface‐initiated polymerizations, particularly reversible deactivation radical polymerizations, and macromolecules adopt extended conformations that differentiate them from classical polymer films. This review explores various applications of PBs, emphasizing their macromolecular ordering, dynamic conformational changes, anisotropic properties, and so forth. The growing interest in utilizing PBs for functional coatings is discussed in various fields, including electronic, biological, and environmental applications. In electronic applications, PBs find relevance in photovoltaics, energy storage devices, organic light‐emitting diodes, and organic electronics, showcasing their potential in advancing electronic technologies. In biological applications, they contribute to the formation of antifouling and antibacterial coatings, as well as superior lubrication and cellular adhesion, making them valuable in biomedical settings. Other applications include biosensors, bioimaging systems, and drug delivery systems, highlighting their significant contributions to medical advancements. Additionally, PBs play an important role in environmental applications such as water and wastewater treatment. A variety of recent examples of the applications of surface‐grafted PBs are presented, providing insights into their unique properties and architectures that contribute to their success in demanding areas of science and technology.
