Realizing Color Transitions for Three Copper (I) Cluster Organic-Inorganic Hybrid Materials by Adjusting Reaction Conditions.

Copper iodide organic-inorganic hybrid materials have been favored by many researchers in the field of solid-state lighting (SSL) due to their structural diversity and optical adjustability. In this paper, three isomeric copper iodide cluster hybrid materials, CuI(L)(1), CuICl(L)(2) and CuI(L)) (3) (L=1-(4-methylpyrimidin-2-yl)-1,4-diazabicyclo[2.2.

A dual-mode sensing platform coupling two-signal ratiometric and colorimetric methods for detecting Au based on surface state-regulated carbon nanodot.

The considerable risk posed by Au residues to the environment and human health has sparked interest in researching Au monitoring techniques. The detection results in the usual ratio mode are more reliable. In this work, we develop a dual-mode strategy based on reducing carbon dots coupling with two-signal ratiometric and colorimetric methods for high-sensitivity, good-selectivity, and wide-range detection of Au.

An intelligent "chemical tongue" for high-order monitoring ATP-related physiological phosphates and ATP hydrolysis through diverse transduction principles.

For discriminating diverse analytes and monitoring a specific chemical reaction, the emerging multi-channel "chemical nose/tongue" is challenging multi-material "chemical nose/tongue". The former contributes greatly to integrating different transduction principles from a single sensing material, avoiding the need for complex design, high cost, and tedious operation involved with the latter. Therefore, this high-order sensing puts a particular emphasis on the effects of encapsulation.

Construction of an effective ratiometric fluorescent sensing platform for specific and visual detection of mercury ions based on target-triggered the inhibition on inner filter effect.

Sensitive and selective determination of mercury ion (Hg) is critical for human health and environmental monitoring. Herein we construct an effective ratiometric fluorescent sensing platform by combining green fluorescent polymer carbon dots (PCDs) and red fluorescent tetraphenylporphyrin tetrasulfonic acid hydrate (TPPS) for specific and visual detection of Hg. The fluorescence of PCDs can be quenched by TPPS through inner filter effect (IEF).
