Construction of metallo-triangles with cis-TPE motifs and fluorescence properties

Abstract

Two metallo-triangles SA and SB with cis-TPE motifs were constructed and their fluorescence properties were explored. Compared with dilute solution, both triangles SA and SB exhibited significant AIE behavior in...

Coordination-Induced Conformational Control Enables Highly Luminescent Metallo-Cages

“…To address this issue, in 2001, Tang et al developed aggregation-induced emission (AIE) fluorophores, which can enhance luminescence in the aggregation state . However, AIE-active fluorophores generally face difficulties in emitting intense fluorescence in the dilute solution state due to high nonradiative decay caused by the free rotation of the benzene ring. , More importantly, the variety of AIE fluorophores is very limited, so scientists are still trying various methods to avoid the ACQ behavior of the traditional chromophore, for example, the introduction of large steric hindrance groups, , covalent doping, , wrapping and adsorption of other particles, and so on. Although these methods reduce the impact of aggregation, they still have disadvantages such as complex synthesis, low yield, and destruction of the original functionality of the material.…”
