Photo-sensitive hybrids constructed from diphenyliodonium and metal-thiocyanates: photo-induced structure and property transformations

Abstract

Strong electron-poor cation diphenyliodonium was firstly incorporated with transition metal thiocyanates to obtain three new photo-sensitive hybrids, (DPI)3[Mn(SCN)5(H2O)]∙0.25H2O (α-1), {(DPI)2[Ni(SCN)4]}n (α-2) and {(DPI)6[Cd3(SCN)12]}n (α-3) (DPI+ =diphenyliodonium), whose photo-induced structural transformations...

Three photochromic materials based on POMs and viologens for UV probing, visual detection of metal ions and amine detection

“…Inkless printing and erasable experiments were carried out according to literature methods. 39,40 First, compounds 1–3 were ground into powders, respectively. Then, a certain amount of the powders was dissolved in ethanol.…”

Noncovalent Chelation by Halogen Bonding in the Design of Metal-Containing Arrays: Assembly of Double σ-Hole Donating Halolium with CuI-Containing O,O-Donors

“…A specific feature of the noncovalent chelation is a greater variability in the size of thus formed metallocycles than that in the conventional covalent chelation. While classic metallacycles in the vast majority of instances consist of five or six atoms, the reported noncovalent iodonium­(III) cyclic systems contain 4 (structures C and D , Figure ), 8 (structures of complexes 3c – e , and also structures A , E , and F in Figure ), and even 11 atoms (structure B in Figure ). This difference in the ring sizes of covalent and noncovalent chelated species can be accounted for by an extended MEP area on the I III site, which determines electrostatic interactions in a broader range.…”

“…The first type structures are well known (see, for example, our reports 7−9 16) Å; Bondi 16 ∑ vdW I + O = 3.50 Å) linking the ether O atom and the area in between the two σ-holes of the iodonium cation 17 (structure A, Figure 2); 1,2-substituted phenylenes bearing two carbonyl moieties 18 (B); the associates of diphenyliodonium with tetrachloroplatinate 19 (C), Bi III halides 20 (D), and metal-thiocyanate complexes 21…”

“…270 known X-ray diffraction (XRD), structures of various iodonium salts. These examples include cocrystals of diaryliodonium salts with 18-crown-6 featuring the O,O-chelation accompanied by the central I···O short contact (3.0765(16) Å; Bondi ∑ vdW I + O = 3.50 Å) linking the ether O atom and the area in between the two σ-holes of the iodonium cation (structure A , Figure ); 1,2-substituted phenylenes bearing two carbonyl moieties ( B ); the associates of diphenyliodonium with tetrachloroplatinate ( C ), Bi III halides ( D ), and metal-thiocyanate complexes ( E and F ).…”

A series of naphthalenediimide-based metal–organic frameworks: synthesis, photochromism and inkless and erasable printing

“…1,2 Inkless and erasable printing as a new alternative technology has attracted extensive attention for zero printing ink, low energy consumption and reusable printing paper. [3][4][5][6][7] However, searching for materials that can be applied in inkless and erasable printing remains a huge challenge.…”
