Recently, stimuli-responsive materials have attracted great attention, while most of them respond to single or two stimuli. Thus, it is essential design multifunctional and develop their applications. The strategy that constructing high-dimensional coordination polymers facilitates the application scope a viologen-based photochromic system put forward confirmed for first time. Herein, novel multistimuli-responsive Zn-MOF with two-dimensional framework has been successfully designed synthesized. Complex 1 exhibits chromic behavior under variety external stimuli such as 365 nm UV, X-rays, heat, electricity, ethylamine. More interestingly, crystal state complex displays dual fluorescence room-temperature phosphorescence (RTP) emission emits yellow afterglow when turning off UV lamp. In addition, Eu(III)-functionalized hybrids, Eu3+@Zn-MOF, were prepared by coordinated postsynthetic modification based on viologen complexes sample Eu3+@Zn-MOF inherits characteristics gives distinctive europium ions. Based multicolor switching possible practical utilization was developed in fields inkless, erasable print media, electrochromic information tag printing, encryption, anticounterfeiting.

The development of new responsive smart materials has been highly desirable in the recent decade due to growing demand our daily life, and extended viologen-based coordination polymers are regarded as proper promising candidates for stimuli-responsive study. A tri(pyridinyl)pyridine Kagome dual (kgd) topological polymer, [Mn3Cl4(tpptb)2]·Cl2·(H2O)2, (tpptb = N,N',N″-tri(3-carboxybenzyl)-2,4,6-tri(pyridinium-4-yl)pyridine; 1) solvothermally synthesized, which can selectively respond soft X-ray Al-Kα (λ 8.357 Å) irradiation but not UV light hard X-rays λ < 1.5418 Å at room temperature. Appealingly, 1 is very sensitive convenient visual detection various volatile amine vapors, especially ethylamine vapors a low concentration 100 ppm, vapochromic sample be recovered after exposure air sequence amines vapochromism could rationalized by combined consideration vapor pressure, molecular size, electron-donor ability molecules well void spaces 1. In addition, exhibits an obvious hydrochromic transformation upon heating anhydrous atmosphere. Combined XPS EPR confirmed that these physical chemical stimuli cause electron transfer from electron-rich groups quaternary nitrogen atoms ligand generate charge-separated radicals, leading X-ray-induced photochromic selective behavior Such indicates it will become convenient, recyclable, practical multifunctional material environmental sensing. These results provide effective avenue rational design synthesis chromic potential use sensing devices.
