On the other hand, high-power blue emitters are still uncommon, especially those that can achieve the Commission Internationale de l\u2019Eclairage (CIE, X, Y) coordinates of (0.14, 0.08) in the National Television System Committee (NTSC) blue standard and have high external quantum efficiencies (EQE) of more than 5% because their molecular design presents an enormous challenge. Therefore, creating effective, stable, pure, and deep blue fluorescent materials is vital. Here, it is addressed how useful blue fluorescent Zn (II) complexes are for making organic light-emitting diodes (OLEDs). Utilizing Zn (II) complexes is appealing because of their favourable luminous characteristics, acceptance and mobility, and affordability. This mini-review article aims to provide an overview of Zn (II) complexes that emit blue fluorescent light and have been reported since 2018, while highlighting the unique qualities that make them appropriate OLED materials.<\/jats:p>","DOI":"10.3390\/molecules28135272","type":"journal-article","created":{"date-parts":[[2023,7,10]],"date-time":"2023-07-10T00:54:23Z","timestamp":1688950463000},"page":"5272","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["A Review: Blue Fluorescent Zinc (II) Complexes for OLEDs\u2014A Last Five-Year Recap"],"prefix":"10.3390","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6353-4374","authenticated-orcid":false,"given":"Thompho Jason","family":"Rashamuse","sequence":"first","affiliation":[{"name":"Nanotechnology Innovation Centre, Health Platform, Advanced Materials Division, Mintek, Private Bag X3015, Randburg 2125, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2683-8656","authenticated-orcid":false,"given":"Reagan Lehlogonolo","family":"Mohlala","sequence":"additional","affiliation":[{"name":"Nanotechnology Innovation Centre, Health Platform, Advanced Materials Division, Mintek, Private Bag X3015, Randburg 2125, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena Mabel","family":"Coyanis","sequence":"additional","affiliation":[{"name":"Nanotechnology Innovation Centre, Health Platform, Advanced Materials Division, Mintek, Private Bag X3015, Randburg 2125, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nomampondo Penelope","family":"Magwa","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of South Africa, Private Bag X6, Florida, Roodepoort 1710, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5874","DOI":"10.1039\/C9TC00204A","article-title":"Blue organic light-emitting diodes: Current status, challenges, and future outlook","volume":"7","author":"Lee","year":"2019","journal-title":"J.
