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. 🔗 https://t.co/YxF3xUKjkx

Using the same precursor, we steer on-surface cyclodehydrogenation by surface structure: Cu(110) → isokekulene Cu(111) → kekulene STM + DFT reveal how surface structure directs selectivity. Paper: https://t.co/IU2bJhDA1J
