In 1, the Zn atom is pentacoordinated with a N3O2 irregular trigonal bipyramidal coordination environment, like the geometries in compounds 3\u20137, whereas in structure 2 the metal atom is envisaged as possessing a distorted N3O3 octahedronal environment. All the compounds show interesting photoluminescent properties in solid states and solutions in DMF and DMSO, which are reported along with their TG-DTA thermal decomposition processes, UV-vis absorption spectroscopy and fluorescence quantum yields in DMF and DMSO.<\/jats:p>","DOI":"10.3390\/molecules23071735","type":"journal-article","created":{"date-parts":[[2018,7,16]],"date-time":"2018-07-16T11:38:50Z","timestamp":1531741130000},"page":"1735","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Study on the Photoluminescent and Thermal Properties of Zinc Complexes with a N6O4 Macrocyclic Ligand"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3117-0857","authenticated-orcid":false,"given":"Xingyong","family":"Xue","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Guangxi University, Nanning 530004, China"},{"name":"Guangxi Colleges and Universities Key Laboratory of Applied Chemistry Technology and Resource Development, Nanning 530004, China"}]},{"given":"Qijun","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Guangxi University, Nanning 530004, China"}]},{"given":"Fusen","family":"Mai","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Guangxi University, Nanning 530004, China"}]},{"given":"Xing","family":"Liang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Guangxi University, Nanning 530004, China"}]},{"given":"Yichen","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Guangxi University, Nanning 530004, China"}]},{"given":"Jiahe","family":"Li","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Guangxi University, Nanning 530004, China"}]},{"given":"Yanling","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Guangxi University, Nanning 530004, China"}]},{"given":"Dengfeng","family":"Yang","sequence":"additional","affiliation":[{"name":"Guangxi Academy of Sciences, Guangxi Beibu Gulf Marine Research Center, Guangxi Key Laboratory of Marine Natural Products and Combinatorial Biosynthesis Chemistry, Nanning 530007, China"}]},{"given":"Zhen","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Guangxi University, Nanning 530004, China"},{"name":"Centro de Qu\u00edmica Estrutural, Complexo I, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Av.
