Although copper(I) iodide clusters are well known for their vapochromic luminescence arising from the structural flexibility of Cu\u2500I frameworks, hydrogen\u2010bonded Cu(I) architectures with dynamic host\u2013guest interactions remain rare. Herein, we report a series of hydrogen\u2010bonded Cu\u2500I network architectures assembled from identical molecular building blocks, exhibiting multicolor crystalline photoluminescence and structure\u2010dependent responses to solvent vapor. Depending on the Cu\u2500I assembly mode, three distinct architectures, namely a polymorphic one\u2010dimensional single\u2010ladder chain, a double\u2010ladder chain, and a cubane\u2010like molecular cluster, were obtained and structurally characterized. The single\u2010ladder framework exhibits polymorphism accompanied by distinct emission colors.\n                    <jats:italic>N<\/jats:italic>\n                    ,\n                    <jats:italic>N<\/jats:italic>\n                    \u2010dimethylformamide (DMF) desorption induced on\/off switching in emission intensity for the double\u2010ladder chain and a change in emission color in the cubane\u2010like molecular cluster. Both photoluminescence responses were reversible upon re\u2010exposure to DMF vapor; however, recovery of the initial long\u2010range crystal structure occurred only in the double\u2010ladder chain. The Cu\u2500I assembly mode thus gives rise to two distinct PL\u2010reversible vapochromism: intensity switching and color switching. These findings establish hydrogen\u2010bond\u2010assisted structural design for tuning how guest exchange modulates photoluminescence intensity and color.\n                  <\/jats:p>","DOI":"10.1002\/cptc.70305","type":"journal-article","created":{"date-parts":[[2026,10,9]],"date-time":"2026-10-09T05:57:34Z","timestamp":1791525454000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Vapochromic Photoluminescence in Structurally Diverse Hydrogen\u2010Bonded Copper(I) Cluster Networks"],"prefix":"10.1002","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-9141-8884","authenticated-orcid":false,"given":"Kazuma","family":"Takahara","sequence":"first","affiliation":[{"name":"Department of Material Science Graduate School of Science University of Hyogo  Ako\u2010gun Hyogo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rin","family":"Suhara","sequence":"additional","affiliation":[{"name":"Department of Material Science Graduate School of Science University of Hyogo  Ako\u2010gun Hyogo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiki","family":"Ozawa","sequence":"additional","affiliation":[{"name":"Department of Material Science Graduate School of Science University of Hyogo  Ako\u2010gun Hyogo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5767-7245","authenticated-orcid":false,"given":"Masaaki","family":"Abe","sequence":"additional","affiliation":[{"name":"Department of Material Science Graduate School of Science University of Hyogo  Ako\u2010gun Hyogo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,8]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1021\/ja8019356"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1039\/c0cc01434f"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1246\/bcsj.80.287"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1021\/cr300396p"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.9229483"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1021\/ic300173t"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1039\/D6CC01278G"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.0c05277"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.chemmater.1c04408"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1039\/b001001o"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jssc.2024.124639"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jpclett.2c00494"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1021\/acsmaterialslett.4c00290"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.inorgchem.7b03160"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.inorgchem.0c01967"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.inorgchem.3c02634"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1021\/ic201128a"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1246\/cl.180435"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jpclett.9b03478"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.inorgchem.7b01870"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.1039\/C1DT11462J"},{"key":"e_1_2_8_23_1","doi-asserted-by":"crossref","first-page":"466","DOI":"10.1524\/ncrs.2009.0203","article-title":"Crystal Structure of Tetra\u20103\u2010Iodo\u2010Tetrakis[(nicotine)copper(I)], Cu4I4(C10H14N2)4","volume":"224","author":"Jiang Z.
