Published: June 2023

We report columnar liquid-crystalline thiophene-oxadiazole molecules, which can be oriented by electric field and exhibit photodiode properties with an open-circuit voltage of 1 V. Their yellow luminescence can be excited by UV-visible or infrared light. Their room-temperature phosphorescence turns brighter upon heating.

Background: Schistosomiasis is caused by infection with parasitic worms and affects more than 250 million people globally. The detection of schistosome derived circulating cathodic and anodic antigens (CCA and CAA) has proven highly valuable for detecting active infections, causing both intestinal and urinary schistosomiasis.

Aim: The combined detection of CCA and CAA was explored to improve accuracy in detecting infections.

Photochromic Sodalites: From Natural Minerals to Advanced Applied Materials.

Mineralogical Society of Antwerp, Boterlaarbaan 225, 2100 Deurne, Belgium.

ConspectusWhile photochromic natural sodalites, an aluminosilicate mineral, were originally considered as curiosities, articles published in the past ten years have radically changed this perspective. It has been proven that their artificial synthesis was easy and allowed compositional tuning. Combined with simulations, it has been shown that a wide range of photochromic properties were achievable for synthetic sodalites (color, activation energy, reversibility, etc.

Constructing highly conjugated three-dimensional covalent organic frameworks (3D COFs), particularly those with luminescent features, remains a significant challenge. In this work, we successfully synthesized a 3D COF, named 3D-Py-SP-COF, using a rigid and orthogonal spirobifluorene building block for the spatial 3D structure construction and planar pyrene as luminescent units. The incorporation of the pyrene and the unique rigid 3D network structure endow 3D-Py-SP-COF with fluorescent properties.

Adsorption of Eu and Gd on high-charge micas as inner-sphere complexes.

Departamento QUIPRE, Universidad de Cantabria, Avda. Los Castros 46 39005 Santander, Spain; Grupo de Nanomedicina, IDIVAL, Avda. Cardenal Herrera Oria s/n, 39011 Santander, Spain. Electronic address:

High-charge micas exhibit improved adsorption properties and are a promising alternative clay material for the engineered barrier in deep geological repositories. When combined with Eu cations, they serve as an in situ luminescent probe for tracking the physical-chemical changes occurring in this engineered barrier over the long term. Therefore, a better understanding of the local environment of the lanthanide is highly desirable to comprehend the specific behavior of these systems.

Key Laboratory of Medicinal Chemistry for Natural Resource of Yunnan, University Ministry of Education, School of Chemical Science and Technology, Yunnan University, Kunming 650091, P. R. China.

Ethylenediamine (EDA), as an important chemical raw material and fine chemical intermediate, has been widely applied in various industries. Real-time monitoring of EDA is highly desirable in daily life due to its potential threat to human health. Herein, we report a molecular probe named 4,4'-(9-carbazole-3,6-diyl)bis(1-(naphthalen-2-ylmethyl)pyridin-1-ium) iodide (p-N-DPC·I) with ratiometric luminescent and colorimetric dual-mode responses toward EDA, endowing a highly sensitive and selective detection method for its real-time monitoring.
