“…On the contrary, 4 increases gradually and stabilizes after four cycles. The photocurrents of 1 , 3 and 4 all stabilize at about 4.40 × 10 –7 , 4.55 × 10 –7 and 4.75 × 10 –7 A, respectively The current intensities of this work are weaker than the other viologen‐containing compounds, such as (MV) 2 [Li 4 (L) 2 (H 2 O) 6 ] and MV[Ni(4‐pedt) 2 ] 2 , but stronger than metalloviologen‐containing hybrids . It has been proved that that the pure organic‐coated sole system shows no photocurrent response, therefore, in this work, iodocuprate–quaternary phosphorus donor–acceptor systems are the reason for photocurrent generation.…”

Four (triphenyl)phosphonium-based quaternary phosphorus salts with different substituents (varying from methyl to n-butyl) were selected to be structural directed agents (SDAs) to construct four iodocuprate(I) hybrids via solution method, i.e., [(PPh 3 Me)(Cu 3 I 4 )] n (1), [(PPh 3 Et)(Cu 3 I 4 )] n (2), (PPh 3 iPr) 2 (Cu 2 I 4 ) (3), [(PPh 3 nBu)(Cu 3 I 4 )] n (4). The inorganic iodocuprates in 1, 2 and 4 are 1-D (Cu 3 I 4 ) n nchains constructed from Cu 5 I 11 units, but (Cu 2 I 4 ) 2in 3 is a di-nuclear cluster. Interestingly, the strength of Cu···Cu and π-π stacking interactions are weakened with the lengthening of alkyl groups on P-atom. The best water stability of 4 can be ascribed to the better hydrophobicity of n-butyl group, which deters the dispersing of [a]

Host-guest encapsulationo ff unctional organic dye into ap orousm etal-organic framework can give rise to the developmento fn ew functional materials. In this work, by intercalating the stilbazolium-type dye (DEAST)I (4'-diethylamino-N-methyl stilbazolium) into four lanthanide layered metal-organic complexes (Ln-LMOCs), i. e. (3), Er (4)), four responsive (DEAST)I@Ln-LMOCc omposites have been prepared, serving as multifunctional performance platform. The core-shell structures of (DEAST)I@Ln-LMOC composites have been fully characterizedb yI R, UV/Vis, PXRD, SEM, TEM, TGA and ESR. Significantly,a fter intercalation of dyes, the (DEAST)I@Ln-LMOC composites exhibit enhanced luminescent sensing properties in detecting Fe 3 + with much higherw ater stabilities. The luminescent sensing behavior stems from the fluorescencer esonance energy transfer (FRET) from the p-electron-rich BTB ligands to the Fe 3 + ,a nd their higher water stabilities are induced by electrostatici nteractions and lower porosity.S pecially,t he characteristic emissions of Sm 3 + will not be affected after the encapsulation guest dyes, which provideatheoretical guide for the modulation of luminescence devices.F inally,b etter ion conductivities andd iminished photocurrents can be achieved after the embedding of the functional organic dye. In all, the formation of (DEAST)I@Ln-LMOC composites with core-shell structures can be utilized as am ultifunctional platform with good stability.[a] L.

“…In the past decades, halometallate-based functional materials have attracted great attention due to their versatile structure and unique properties, based on which many novel applications have emerged, such as perovskite solar cells, 1,2 luminescence, 3 molecular switches, 4 nonlinear-optic devices 5 and chromisms. 6 Among the halometallate hybrids, d 10 silver(I) halides have captured special interest for the following reasons: first, various anion dimensionalities based on rich coordination geometries of the Ag(I) ion (from linear MX 2 , triangular MX 3 , tetrahedral MX 4 , and octahedral AgX 6 ) and variable connection modes; 7 second, unique physical properties of electron-rich halo-argentates. 8 To date, in the haloargentate-based hybrids, the templates include organic cations, metal ions and metal-organic complexes.…”

Background: The realization of multifunction in one bulk material is fascinating for developing a new generation of devices. Quaternary phosphorus salts were seldom utilized as templates in haloargentate systems, and the hybridization of alkyl(triphenyl)phosphonium with halometallate will be a good strategy for the development of multifunctional material, especially for biological material. Methods: Under the template of (triphenyl)phosphonium-based quaternary phosphorus salts with different spacer lengths (n=2, 3, 4), three bromoargentate hybrids were constructed via the solution method, ie, (1,2-DBTPP)(Ag 2 Br 4) (1), {(1,3-DBTPP) 2 (Ag 7 Br 11)]•CH 3 CN•H 2 O} n (2), and {[(1,4-DBTPP)(Ag 5 Br 7)](CH 3 CN) 2 •H 2 O} n (3) (1,2-DBTPP 2+ =ethane-1,2-diylbis (triphenyl)phosphonium, 1,3-DBTPP 2+ =propane-1,3-diylbis (triphenyl)phosphonium, 1,4-DBTPP 2 + =butane-1,4-diylbis (triphenyl)phosphonium)). Results: The (Ag 7 Br 11) n 4nchain in 2 is a new type of 1-D bromoargentate chain constructed from cubane-like Ag 4 Br 4 nodes, AgBr 4 tetrahedrons and AgBr 3 triangles. Interestingly, by elongating spacer n from 2 to 4, argentophilicity interactions are weakened, and the hydrogen bonds are strengthened. Consequently, their water stabilities and photocurrents are improved, in which the Ag-4d/Br-4p to π* anti-bonding orbital of the quaternary phosphorus transfer is facilitated. Furthermore, the greenish blue emissions can be detected. Finally, high inhabitation rates against Streptococcus mutans and Candida albicans can be observed in 2 and 3. Conclusion: In all experiments, by elongating the spacer lengths of quaternary phosphorus salts, multifunctions were integrated in the quaternary phosphorus/bromoargentate hybrids, including greenish blue luminescence, repeatable photocurrent responses and durable antimicrobial activities with enhanced water stability. This work could provide a theoretical guide for the design of new biologically multifunctional materials.
