A silyloxy-functionalized tetraphenylethylene (TPE) derivative shows a remarkable change in the absorption spectrum on deprotection with fluoride ions. The reaction process is highly selective for fluoride and the resulting charge transfer band results in a bright green solution. A simple selective visual assay of aqueous fluoride ions was also obtained by the impregnation of cellulose strips with the TPE derivative.
Switching the emission of tetrakis(4-methoxyphenyl)ethylene among three colors in the solid state

Emission of a luminogen could be switched among three colors in the solid state by transformation among three different aggregation states. The partly amorphous solid of the luminogen exhibits excitation dependent emission due to the contribution of both amorphous and crystalline parts to the photoluminescence intensity.
Insights into the general and efficient cross McMurry reactions between ketones
Duan, Xin-Fang,Zeng, Jing,Lue, Jia-Wei,Zhang, Zhan-Bin
, p. 9873 - 9876 (2006)
The selective cross McMurry couplings of diaryl or aryl ketones with various substituted ketones were achieved in 53-94% isolated yields. It is believed that the strong affinity of the substituents to the low-valent titanium surface plays an important role in regards to moderating selectivity. Through the introduction of such substituents followed by their removal post McMurry coupling, structurally similar ketones can be effectively cross-coupled.

Simple Modifications for the Facile Preparation of 1,1,2,3,4,4-Hexaaryl-1,3-butadienes
Sakaguchi, Tomoya,Kusumoto, Naoki,Shimomura, Osamu,Ohtaka, Atsushi
, (2022/01/11)
A facile preparation of 1,1,2,3,4,4-hexaaryl-1,3-butadienes which are important molecules due to their aggregation-induced emission (AIE) activity was achieved by simple modifications of the reaction conditions reported in the previous work. In this react
Identification of the donor-substitution effect of tetraphenylethylene AIEgen: Synthesis, photophysical property analysis, and bioimaging applications
Kim, Dokyoung,Kim, Na Hee
, (2022/01/24)
Various aggregation-induced emission luminogen (AIEgen) derivatives based on TPE (tetraphenylethylene) containing the electron-donating moiety (–NMe2, –OMe) and bromine (–Br) moiety were prepared, which are key intermediates for tuning the emis
