Many thanks to Dr. Yoshihide Seino and Mr. Kurita @UNISOKU_PR and Dr. Andy Bettac @nanoscore for their excellent work during the installation! Now we are looking forward to the second phase, when the Raman system of the USM1400-LT TERS will be installed.

New paper in Nature Chemistry: We find that on-surface radical ring-opening polymerization of [6]CPP on Cu(111), produces near micrometer-long poly(para-phenylene) (PPP) chains — far beyond typical polymer lengths obtained by On-Surface Synthesis.

Our new @J_A_C_S paper: π-extended quintulene that traps a single Au atom and can be flipped with an STM tip: a step toward curved nanocarbons via on-surface synthesis.

🚀 New in @J_A_C_S
On-surface synthesis of quasi-planar, π-extended cycloparaphenylenes with tailored ring sizes and electronic properties!
💡 Planarization + π-extension → reduced gaps
🌀 Strained geometry, edge-localized orbitals
🔬 STM/STS + DFT

Porphyrin complexes with one metal atom and one N-H hydrogen are extremely rare.
We made LiHTPP by exposing tetraphenylporphyrin films to Li vapor under UHV.
It is stable, sublimable, and reveals a nonplanar structure and unique metalation pathway.
