2017年12月1日 · 7,7,8,8-Tetracyanoquinodimethane (TCNQ) has been used as a versatile building block for designing organic conductors and assemblies. It is believed that the fluorescence quantum yield of TCNQ is extremely low and …

2022年5月9日 · By selecting the fluorene (Flu) and the 7,7′,8,8′-tetracyanoquinodimethane (TCNQ) as functional constituents, the Flu-TCNQ cocrystal prepared shows deep red emission at 702 nm, which is comparable to the commercialized red quantum dot. The highest electron mobility of organic field-effect transistor (OFET) based on Flu-TCNQ is 0.32 cm 2 V −1 s −1.

2013年11月12日 · We demonstrate the tunability of the photoluminescence (PL) properties of monolayer (1L)-MoS 2 via chemical doping. The PL intensity of 1L-MoS 2 was drastically enhanced by the adsorption of p-type dopants with high

2025年1月15日 · Here, we synthesized TCNQ modified BiOIO 3 (TCNQ/BiOIO 3) catalyst via hydrothermal process for the selective photocatalytic removal of organic pollutants. Its physicochemical properties, including morphology, crystal structure, elemental chemical state, light adsorption capacity and electron-hole separation performance, were studied via a ...
