Fullerene Derivative-Modified SnO2 Electron Transport Layer for Highly Efficient Perovskite Solar Cells with Efficiency over 21%

“…NPC 60 -OH was synthesized according to the previous report using the one-step method. Fullerene C 60 , 4-hydroxybenzaldehyde, and N-methylglycine were dissolved in toluene and then the mixture was refluxed under an N 2 atmosphere. − The synthetic route is illustrated in Figure a, the detailed synthetic process and purification steps are shown in the Supporting Information. Mass spectrum analysis was employed to confirm the successful synthesis of NPC 60 -OH (Figure b).…”

“…Herein, NPC 60 -OH was successfully introduced into the Pero-SCs via a spin-coating method to modify SnO 2 ETL. As a fullerene derivative, the application of NPC 60 -OH fullerene has several advantages. − It could be synthesized under a low temperature of 125 °C by a facile one-step process, involving only the nonhalogen solvent of toluene. Moreover, the NPC 60 -OH/SnO 2 ETLs possessed high electron mobility, which promoted electron transportation and further enhanced the PCE of the device.…”

Preparation and characterization of polydopamine and n-butyl methacrylate copolymer coatings on titanium–nickel alloy stents

“…20 To address this challenge, we developed a new approach for synthesizing an amphiphilic and water-insoluble block copolymer, poly( n -butyl methacrylate)- b -poly( N -vinylpyrrolidone) (PBMA- b -PVP), through Reversible Addition-Fragmentation Chain Transfer polymerization (RAFT). This method enables precise control over the polymeric structure and molecular weight, 21 and the utilization of a block copolymer eliminates potential microphase separation and the resultant coating non-uniformity and instability in properties that may arise from the simple physical mixture of two homopolymers.…”

Norbornadienes: Robust and Scalable Building Blocks for Cascade “Click” Coupling of High Molecular Weight Polymers

“…A more cost-effective and scalable metal-free click platform for polymer synthesis is the Diels–Alder (DA) cycloaddition reaction. DA systems have been utilized across numerous applications ranging from polymer cross-linking, , nanoparticle, surface functionalization, and preparation of antibody–drug conjugates . Furan or anthracene-based dienes, in combination with maleimide dienophiles, are arguably the most commonly utilized building blocks for DA cycloaddition couplings in polymer synthesis (Figure a) .…”
