Three-component D–A hybrid heterostructures with enhanced photochromic, photomodulated luminescence and selective anion-sensing properties

Abstract

As an emerging class of hybrid complexes, the donor-acceptor (D-A) hybrid heterostructures combined with both advantages of photoactive organic and inorganic components have provided an excellent platform for the fabrication...

Visual Detection of Triethylamine and a Dual Input/Output Logic Gate Based on a Eu3+-Complex

“…These observations can be attributed to the unique structure of DPPI with imidazole and triphenylamine groups, which are sensitive to the micro-environments changed by the addition of TEA [ 44 , 45 , 46 ]. On one hand, TEA provides active hydrogen protons that result in acid-base interactions; on the other hand, it causes the electronic distribution and energy state changes in the ILCT-structured DPPI ligand due to molecular interactions [ 47 ], and leads to the color emission variations and the TEA detecting capabilities of the Eu 3+ -complex [ 48 , 49 ].…”

Metal–organic framework bearing new viologen ligand for ammonia and Cr2O72− sensing

“…Considering that compounds 1, 2 and 3 are three-dimensional framework structures with channels, they can be applied to ion exchange of ionic pollutants. 11,33,39,40 . Aer some time, the sample is ltered out and allowed to dry.…”

“…At the same time, MOFs designed based on viologen have advantages in chemical sensing/switching and other elds, and their response characteristics can be adjusted by the organization of the D-A block. 1,2,14,15,17,[28][29][30][31][32][33][34][35][36] Ammonia (NH 3 ) is an important industrial raw material with a wide range of uses, but it is also a highly toxic chemical. And even at low concentrations, there is a certain degree of toxicity.…”

“…11,25,37,38 On the other hand, although Cr 2 O 7 2À is widely used in industry, it has carcinogenic effects on the human body and is an environmental pollutant. 11,33,39,40 Therefore, it is particularly important and urgent to design a sensor for detecting ammonia and Cr 2 O 7…”

A Series of Polyoxometalate‐Viologen Photochromic Materials for UV Probing, Amine Detecting and Inkless and Erasable Printing

“…At present, a series of viologen based metalorganic complexes have been obtained, which can exhibit good photochromic properties and amine detection performance. [14][15][16][17][18] However, the combination of viologen and POMs to build new photochromic materials and amine detection materials were rarely observed. Up to now, only a few reports on this series were reported.…”
