Compound 1 is a two-dimensional metal\u2013organic framework composed of a pyramidal Cu4I5 cluster and hexamethylenetetramine, in which hmt-bridged Cu clusters form a two-dimensional (4,4)-connected net with a point symbol of (44\u00b762) (44\u00b762). Compound 2 is a homochiral three-dimensional metal\u2013organic framework material generated through an unusual spontaneous crystallization from achiral precursors. The two compounds were characterized by a series of analyses such as infrared spectroscopy, elemental analysis, circular dichroism spectroscopy, and powder X-ray diffraction. Both of them exhibit unexpected stability under a wide range of conditions of acid and base. In addition, the fluorescence intensity changes regularly under acid\u2013base conditions. Stokes shift shows a good linear relationship with \u2212log\u2009[H+], which makes them become promising acid\u2013base sensors. Compounds 1 and 2 also display selective adsorption and a significant degradation effect on the organic dye methylene blue. In addition, the fluorescence study indicated that compound 2 could be used as a sensor to detect Cr3+.<\/jats:p>","DOI":"10.1021\/acsomega.9b01356","type":"journal-article","created":{"date-parts":[[2019,7,19]],"date-time":"2019-07-19T15:02:33Z","timestamp":1563548553000},"page":"12402-12409","source":"Crossref","is-referenced-by-count":11,"title":["Preparation and Analyses of the Multifunctional Properties\nof 2D and 3D MOFs Constructed from Copper(I) Halides and Hexamethylenetetramine"],"prefix":"10.1021","volume":"4","author":[{"given":"Xiuying","family":"Qiao","sequence":"first","affiliation":[{"name":"Zhengzhou University , , ,","place":["Henan, P.
