The self-organization of 5,10,15,20-tetra(p-hydroxyphenyl)porphyrin (H2THPP) molecules leads to two molecular arrangements on Au(111). One of these is characterized by pair-wise hydrogen bonding between hydroxyl groups and a low packing density which enables a rotation of individual molecules in the structure. A different interaction with stronger chain-like hydrogen bonding and additional interactions of phenyl groups was observed for the s","authors_text":"Carola Mende, Heinrich Lang, Lars Smykalla, Michael Hietschold, Pavel Shukrynau, Tobias R\\\"uffer","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2014-03-25T21:51:18Z","title":"Interplay of hydrogen bonding and molecule-substrate interaction in self-assembled adlayer structures of a hydroxyphenyl-substituted porphyrin"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1403.6516","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:0ef88db6875ff51d8771cd103d0062ee45c668ce8ef85cab0d76eaa4db6c42f3","target":"record","created_at":"2026-05-18T02:48:46Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"a75963f0500c0d6b95d20e88248541f74fae997daf8b1cf8f47293fab61536a7","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2014-03-25T21:51:18Z","title_canon_sha256":"9a21640d54f702980b5e7d0f3598fbf94606f79e8b3d7ccf48f5d5a9174e83d3"},"schema_version":"1.0","source":{"id":"1403.6516","kind":"arxiv","version":2}},"canonical_sha256":"caf9c413315538119e26558d50d184d9a7ec060dcecdcbc2a45044e6d75eff16","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"caf9c413315538119e26558d50d184d9a7ec060dcecdcbc2a45044e6d75eff16","first_computed_at":"2026-05-18T02:48:46.161309Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:48:46.161309Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"aPydb2FoB9ORk7OQHsdwE+OC4mFbzMop9J0pdqhkXy7BvRPpqOhZRpCdiwrnh11sjSwXL67MQrhCvLB4qY7XCg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:48:46.163055Z","signed_message":"canonical_sha256_bytes"},"source_id":"1403.6516","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0ef88db6875ff51d8771cd103d0062ee45c668ce8ef85cab0d76eaa4db6c42f3","sha256:076b78ddb934578d9f94b97c34cc09ae4a5c5926b6e6672075ecbc3243ffac4a"],"state_sha256":"2166dfb6a250590c3aab7dad6d9a8ba668698604d1242841501988da4d9c2454"}
