The compounds present luminescent properties with denoted room temperature phosphorescence (RTP) induced by the proximity of the gold(I) heavy atom that favors intersystem crossing and triplet state population. The emissive properties of the compounds together with the planarity of their chromophore were used to investigate their potential as hosts in the molecular recognition of different polycyclic aromatic hydrocarbons (PAHs). Naphthalene, anthracene, phenanthrene, and pyrene were chosen to evaluate how the size and electronic properties can affect the host:guest interactions. Stronger affinity has been detected through emission titrations for the PAHs with extended aromaticity (anthracene and pyrene) and the results have been supported by DFT calculation studies.<\/jats:p>","DOI":"10.3390\/molecules26092444","type":"journal-article","created":{"date-parts":[[2021,4,22]],"date-time":"2021-04-22T13:59:14Z","timestamp":1619099954000},"page":"2444","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Using Room Temperature Phosphorescence of Gold(I) Complexes for PAHs Sensing"],"prefix":"10.3390","volume":"26","author":[{"given":"Marian","family":"Rosental","sequence":"first","affiliation":[{"name":"Department of Inorganic and Organic Chemistry, Inorganic Chemistry Section, Universitat de Barcelona, Mart\u00ed i Franqu\u00e8s 1, 08028 Barcelona, Spain"},{"name":"Institute of Inorganic Chemistry, Heidelberg University, Im Neuenheimer Feld 270, 69120 Heidelberg, Germany"}]},{"given":"Richard N.","family":"Coldman","sequence":"additional","affiliation":[{"name":"Department of Inorganic and Organic Chemistry, Inorganic Chemistry Section, Universitat de Barcelona, Mart\u00ed i Franqu\u00e8s 1, 08028 Barcelona, Spain"}]},{"given":"Artur J.","family":"Moro","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE, Departamento de Qu\u00edmica, Universidade Nova de Lisboa, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9537-5803","authenticated-orcid":false,"given":"Inmaculada","family":"Angurell","sequence":"additional","affiliation":[{"name":"Department of Inorganic and Organic Chemistry, Inorganic Chemistry Section, Universitat de Barcelona, Mart\u00ed i Franqu\u00e8s 1, 08028 Barcelona, Spain"},{"name":"Institut de Nanoci\u00e8ncia i Nanotecnologia (IN2UB), Universitat de Barcelona, 08028 Barcelona, Spain"}]},{"given":"Rosa M.","family":"Gomila","sequence":"additional","affiliation":[{"name":"Serveis Cient\u00edfico T\u00e8cnics, Universitat de les Illes Balears, Crta de Valldemossa km 7.5, 07122 Baleares, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7840-2139","authenticated-orcid":false,"given":"Antonio","family":"Frontera","sequence":"additional","affiliation":[{"name":"Departament de Qu\u00edmica, Universitat de les Illes Balears, Crta de Valldemossa km 7.5, 07122 Baleares, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0528-1967","authenticated-orcid":false,"given":"Jo\u00e3o Carlos","family":"Lima","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE, Departamento de Qu\u00edmica, Universidade Nova de Lisboa, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1289-1587","authenticated-orcid":false,"given":"Laura","family":"Rodr\u00edguez","sequence":"additional","affiliation":[{"name":"Department of Inorganic and Organic Chemistry, Inorganic Chemistry Section, Universitat de Barcelona, Mart\u00ed i Franqu\u00e8s 1, 08028 Barcelona, Spain"},{"name":"Institut de Nanoci\u00e8ncia i Nanotecnologia (IN2UB), Universitat de Barcelona, 08028 Barcelona, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"12081","DOI":"10.1021\/acsami.7b14473","article-title":"Functional 1,8-Naphthalimide AIE\/AIEEgens: Recent advances and prospects","volume":"10","author":"Gopikrishna","year":"2018","journal-title":"ACS.
