A simple and effective method to prepare highly efficient fluorescent multi-walled carbon nanotubes (MWCNTs) is reported. The quantum yield of the as-prepared MWCNTs is up to 0.25, and increases with the shortening of the aliphatic chain of the diamines functionalized on the tubes. The as-prepared MWCNTs have high selectivity for several transition metal ions based on fluorescence quenching which is due to the complexes of tubes and metal ions.

Esterase-Activated Precipitating Strategy to Achieve Highly Specific Detection and Long-Term Imaging of Calcium Ions by Aggregation-Induced Phosphorescence Probe

Zhenni Wang, Zuping Xiong, Weidong Liu, Qiaozhi Zhu, Xiaoxiao Zhang, Yuqing Ding, Chunyan Huang, Hui Feng, Kewei Zhang, Engao Zhu, Zhaosheng Qian

Summary: Spatial and temporal monitoring of bioactive targets such as calcium ions is of vital significance. In this study, an esterase-activated precipitating strategy was proposed to achieve specific detection and long-term bioimaging of calcium ions using a water-soluble aggregation-induced phosphorescence (AIP) probe. The designed probe CaP2 can be efficiently aggregated by calcium ions, resulting in phosphorescence emission. The introduced hydrophilic groups in probe CaP3 enhance water solubility and cellular penetration, enabling selective detection of calcium ions in live cells. The excellent imaging performance of CaP3 in Arabidopsis thaliana seedling roots demonstrates its potential for long-term imaging.

Photochemically Enhanced Emission by Introducing Rational Photoactive Subunits into an Aggregation-Induced Emission Luminogen

Qiaozhi Zhu, Yuqing Zhu, Weidong Liu, Xinni Ping, Xuting Cai, Jiaqi Zuo, Zhaosheng Qian, Hui Feng

Summary: In this study, a rational design strategy was proposed to achieve highly efficient photochemistry-activated fluorescence enhancement by introducing photoactive thienyl and pyridyl groups into an AIE-active tetraarylethene skeleton. The photoactivated fluorescence of the designed AIEgen was found to be attributed to an irreversible cyclized-dehydrogenation reaction under UV irradiation, resulting in a brighter fluorescence product with a rigid and planar structure. The fast transformation and stable product of this photochemical reaction guarantee super stability of photocontrolled patterning, making it suitable for dual-mode patterning and anti-counterfeiting applications.

Base-gated photochromism of C3-Symmetric AIEgens through multicyano-sensitized benzene rings

Yuqing Zhu, Yangbing Chen, Zuping Xiong, Mengyi Jiang, Hui Feng, Zhaosheng Qian

Summary: In this study, photoresponsive functions such as photochromism were successfully incorporated into aggregation-induced emission (AIE) molecules through a simple and low-cost strategy. A series of C3-symmetric molecules with aggregation-induced emission and base-gated photochromism were synthesized, showing excellent photophysical characteristics in solid-state. The base-gated photochromism of these molecules, constructed by low-cost benzene rings, can detect toxic organic bases, attributed to the multicyano-sensitized benzene rings of these AIE luminogens.

Multiwavelength-controlled multicolor photochromism and fluorescence switching based on an efficient photocyclization reaction by introducing two photoactive subunits into AIEgens

Qiaozhi Zhu, Jiaqi Zuo, Xinni Ping, Yuqing Zhu, Xuting Cai, Zuping Xiong, Zhaosheng Qian, Hui Feng

Summary: This study introduces two photoactive units with varied conjugated structures into an AIE-active tetraarylethene skeleton, achieving multicolor photochromic systems with a color and fluorescence dual-signaling mode and selective response to different wavelengths of light. The study finds that the photo-triggered photochromism is attributed to the reversible cyclization/cycloreversion reaction, and the fatigue of photochromism in solution is due to the occurrence of cyclization-dehydrogenation reaction under UV irradiation but it can be avoided when visible light is used. Introducing two photoactive units can also significantly improve the thermal stability of cyclized products and fatigue resistance to UV irradiation, and it can greatly promote the cyclization efficiency in solution enhancing photochromic performance.
