Numerous molecules have been designed and attached to the exfoliated layers, and based on their outstanding properties, perylene based dyes have become one of the most frequently used {\\pi}-detergents. Therefore, the prospect of this micro review is to summarize the most prominent achievements in this rapidly progressing field of research.","authors_text":"Andreas Hirsch, Frank Hauke, Mario Marcia","cross_cats":["cond-mat.mtrl-sci"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2018-05-03T11:27:06Z","title":"Perylene-Based Non-Covalent Functionalization of 2D Materials"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1805.01231","kind":"arxiv","version":1},"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":"sha256:596e021354903dc80c40eae70d9bc1597bd0633a1e5d3179aa1b245dc06283d1","target":"record","created_at":"2026-05-18T00:15:13Z","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":"30b4feefda4bd77bac7598d3ab6a424b9323bb5d9b568a54acdf0293ee4637f9","cross_cats_sorted":["cond-mat.mtrl-sci"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.chem-ph","submitted_at":"2018-05-03T11:27:06Z","title_canon_sha256":"b27e4da4d964efdc189f300ca7bd294261f5e2753c28df252871a277619cdfb1"},"schema_version":"1.0","source":{"id":"1805.01231","kind":"arxiv","version":1}},"canonical_sha256":"0024f92c4eb4f99042c882d4d8c59ded306c9fba4bf73236df42fbc7bcf3b235","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0024f92c4eb4f99042c882d4d8c59ded306c9fba4bf73236df42fbc7bcf3b235","first_computed_at":"2026-05-18T00:15:13.660477Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:15:13.660477Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lp/wNsVLebIYVrsRRTKA6LNbNaV76v8gRp6UmRL+jUF7o2XwpOAc/RHXLYk9u+uWgwO/EYih8ACJRaiPkk/qDw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:15:13.661111Z","signed_message":"canonical_sha256_bytes"},"source_id":"1805.01231","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:596e021354903dc80c40eae70d9bc1597bd0633a1e5d3179aa1b245dc06283d1","sha256:681a18c05036b71e381fb84d2f2b48f19c0b5b31a544d29a63ba296de4c929b6"],"state_sha256":"7ee640942c1c6019c9ea43411b76a6cc568c7088afdbaf20f28caf93b610e4e9"}
