Current research in this area has focused on incorporating organic architectures to functionalize the DTE framework and alter the resulting photophysical properties; however, their syntheses are often not trivial. In this context, we have designed a simple and versatile diimine (<jats:bold>2<\/jats:bold>) containing adjacent 2,5\u2010dimethyl(thienyl) rings in the backbone. This redox active diimine (<jats:bold>2<\/jats:bold>) acts as a precursor to a novel photochromic ligand and has been used to coordinate to both boron and phosphorus elements, along with the synthesis of a phosphorane\u2010side\u2010chain functionalized polymer without further functionalization to the parent DTE framework. A study of the resulting photochromic properties of these compounds revealed that 1) the UV\u2010visible absorption spectra of the closed\u2010ring isomer were dependent of the element present in the N,N\u2032\u2010chelating pocket and 2) incorporating the dithienylethene into a side\u2010functionalized phosphorane polymer greatly increased the closed\u2010\/open\u2010ring reversibility and decreased the formation of by\u2010products.<\/jats:p>","DOI":"10.1002\/chem.201301086","type":"journal-article","created":{"date-parts":[[2013,5,13]],"date-time":"2013-05-13T16:29:44Z","timestamp":1368462584000},"page":"8473-8477","source":"Crossref","is-referenced-by-count":12,"title":["A Versatile Dithienylethene\u2010Functionalized Ph\u2010Diazabutadiene (DAB) Ligand: From Photoswitchable Main\u2010Group Molecules to Photochromic Polymers"],"prefix":"10.1002","volume":"19","author":[{"given":"Jacquelyn T.","family":"Price","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul J.","family":"Ragogna","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,5,13]]},"reference":[{"key":"e_1_2_5_1_2","volume-title":"Molecular Switches","year":"1990"},{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr980069d"},{"key":"e_1_2_5_3_2","unstructured":"For examples of DTE\u2010containing transition\u2010metal complexes see:"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja907434x"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccr.2009.12.036"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1021\/ic801588y"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1021\/ic101298c"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1021\/ic801619v"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/1099-0682(200007)2000:7<1581::AID-EJIC1581>3.0.CO;2-2"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja203946g"},{"key":"e_1_2_5_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja067425r"},{"key":"e_1_2_5_12_2","doi-asserted-by":"publisher","DOI":"10.1021\/ar100041j"},{"key":"e_1_2_5_13_2","doi-asserted-by":"publisher","DOI":"10.1021\/cr100216y"},{"key":"e_1_2_5_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-3055(08)60380-9"},{"key":"e_1_2_5_15_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja105537j"},{"key":"e_1_2_5_16_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja208097a"},{"key":"e_1_2_5_17_2","doi-asserted-by":"publisher","DOI":"10.1021\/ol3004595"},{"key":"e_1_2_5_18_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja808791e"},{"key":"e_1_2_5_19_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.200800869"},{"key":"e_1_2_5_19_3","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200800869"},{"key":"e_1_2_5_20_2","doi-asserted-by":"publisher","DOI":"10.1021\/ic050429x"},{"key":"e_1_2_5_21_2","doi-asserted-by":"publisher","DOI":"10.1002\/ange.201105032"},{"key":"e_1_2_5_21_3","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201105032"},{"key":"e_1_2_5_22_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja304067k"},{"key":"e_1_2_5_23_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja8057919"},{"key":"e_1_2_5_24_2","doi-asserted-by":"publisher","DOI":"10.1021\/ja058459m"},{"key":"e_1_2_5_25_2","doi-asserted-by":"publisher","DOI":"10.1021\/om900420g"},{"key":"e_1_2_5_26_2","doi-asserted-by":"publisher","DOI":"10.1246\/nikkashi.1992.1138"},{"key":"e_1_2_5_27_2","doi-asserted-by":"publisher","DOI":"10.1039\/a809410a"}],"container-title":["Chemistry \u2013 A European Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fchem.201301086","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/chemistry-europe.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/chem.201301086","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,12]],"date-time":"2025-10-12T18:21:47Z","timestamp":1760293307000},"score":1,"resource":{"primary":{"URL":"https:\/\/chemistry-europe.onlinelibrary.wiley.com\/doi\/10.1002\/chem.201301086"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,5,13]]},"references-count":29,"journal-issue":{"issue":"26","published-print":{"date-parts":[[2013,6,24]]}},"alternative-id":["10.1002\/chem.201301086"],"URL":"https:\/\/doi.org\/10.1002\/chem.201301086","archive":["Portico"],"relation":{},"ISSN":["0947-6539","1521-3765"],"issn-type":[{"value":"0947-6539","type":"print"},{"value":"1521-3765","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,5,13]]}}}
