Unveiling Porphyrin-Fused Graphene Nanoribbons for Next-Gen Electronics with our Circular Dichroism instrument??? This study presents a method for synthesizing porphyrin-fused graphene nanoribbons (PGNRs), offering a scalable strategy for incorporating metal atoms and heteroaromatic units into the conjugated backbone. The PGNRs exhibit long chains (>100 nm), a narrow optical bandgap (~1.0 eV), and high local charge mobility (>400 cm^2 V–1 s–1). Remarkably, PGNRs are utilized to fabricate ambipolar field-effect transistors and single-electron transistors with remarkable switching behaviour and multiple Coulomb diamonds, showcasing their potential for electronic device applications. This research opens new possibilities for engineering π-extended nanostructures with tailored electrical and magnetic properties by integrating porphyrin coordination chemistry into graphene nanoribbons. ??

Chemical Vapor Deposition takes the lead in the race to scale up graphene production. With just methane gas and a copper substrate, in the absence of oxygen, high quality graphene emerges. Underlying paper: https://lnkd.in/gUmubjvZ Abstract Chemical vapour deposition (CVD) synthesis of graphene on copper has been broadly adopted since the first demonstration of this process. However, widespread use of CVD-grown graphene for basic science and applications has been hindered by challenges with reproducibility and quality. Here we identify trace oxygen as a key factor determining the growth trajectory and quality for graphene grown by low-pressure CVD. Oxygen-free chemical vapour deposition (OF-CVD) synthesis is fast and highly reproducible, with kinetics that can be described by a compact model, whereas adding trace oxygen leads to suppressed nucleation and slower/incomplete growth. Oxygen affects graphene quality as assessed by surface contamination, emergence of the Raman D peak and decrease in electrical conductivity. Epitaxial graphene grown in oxygen-free conditions is contamination-free and shows no detectable D peak. After dry transfer and boron nitride encapsulation, it shows room-temperature electrical-transport behaviour close to that of exfoliated graphene. A graphite-gated device shows well-developed integer and fractional quantum Hall effects. By highlighting the importance of eliminating trace oxygen, this work provides guidance for future CVD system design and operation. The increased reproducibility and quality afforded by OF-CVD synthesis will broadly influence basic research and applications of graphene. https://lnkd.in/gty_J8XF

Massachusetts Institute of Technology researchers have developed a novel method for producing large-area, transparent graphene electrodes using chemical vapor deposition (CVD) on copper substrates. This advancement holds significant potential for flexible electronics and optoelectronic devices. In our own in-house research (Advanced materials technology lab), at PAU we successfully synthesized high-quality graphene on copper substrates via thermal CVD devices developed by @VAKSIS (Baybars Oral) and developed an effective method to detach it from the copper substrate. Despite this progress, we have made the difficult decision to terminate our study. I remain optimistic about the future applications of graphene and look forward to potential opportunities to revisit this research.

"Scientists have created conducting two-dimensional polymers exhibiting electron mobility comparable to graphene. Their research has been?featured?in the online edition of?Chem. Graphene, called a "dream material," exhibits electron mobility 140 times faster than silicon and a strength 200 times that of steel. However, its lack of a band gap, which is essential for regulating?electrical current, prevents its use as a semiconductor. Researchers have been actively exploring various approaches to develop a semiconductor that shows graphene's exceptional properties. One promising approach is the development of conducting polymers. Researchers are exploring conducting polymers with a fused aromatic backbone, mimicking the chemical structure of graphene, aiming to attain exceptional properties. Yet, challenges arise during synthesis due to the interlayer stacking between growth intermediates, hindering proper polymer growth." #materialscience #2dconductingpolymers
