{"doi":"10.1021/jp303352h","title":"Proton-Assisted Self-Assemblies of Linear Di-Pyridyl Polyaromatic Molecules at Solid/Liquid Interface","abstract":"Proton-assisted self-assemblies of three linear dipyridyl polyaromatic molecules, namely, 4,4′-bipyridine, 1,4-di(4-pyridyl)benzene, and 4,4′-di(4-pyridyl)biphenyl, at the heptanoic acid/highly oriented pyrolytic graphite interface were systematically studied with scanning tunneling microscopy. A major finding was that protons from strong acids could greatly accelerate the assembling processes of 4,4′-bipyridine and 1,4-di(4-pyridyl)benzene molecules and, in the case of 4,4′-di(4-pyridyl)biphenyl molecule, lead to structural transformation in the self-assembling process in analogy to the role of a catalyst in a catalytic process. The experimental results could be rationalized by a simple mechanism involving proton-assisted formation of intermolecular hydrogen bonds, which provides new insights with regards to the self-assembling processes in solutions, especially under acidic bioenvironments.","journal":"The Journal of Physical Chemistry C","year":2012,"id":12228,"datarank":0.40620753016533157,"base_score":2.70805020110221,"endowment":2.70805020110221,"self_citation_contribution":0.40620753016533157,"citation_network_contribution":0.0,"self_endowment_contribution":0.40620753016533157,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":14,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.049,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2012-10-09","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":96770,"name":"Xiaoguang Xu","orcid":"0000-0001-7659-865X","position":1,"is_corresponding":false},{"id":96771,"name":"Jian Shang","orcid":null,"position":2,"is_corresponding":false},{"id":96772,"name":"Jianlong Li","orcid":"0000-0002-8205-9334","position":3,"is_corresponding":false},{"id":96773,"name":"Xinquan Hu","orcid":"0000-0001-8266-4086","position":4,"is_corresponding":false},{"id":96774,"name":"Boon K.
