WebSep 16, 2024 · Mono and tetra phenothiazine (PTZ) functionalized tetraphenylethylene (TPE) derivatives PTZTPE-1 and PTZTPE-4 were designed and synthesized by the Suzuki cross-coupling reactions between PTZ boronate ester and bromo TPEs. The PTZTPE-1 and PTZTPE-4 are highly emissive in the solid state, which is crucial for a molecule to show …

WebOct 21, 2024 · Phenothiazines are tri-heterocyclic donors containing nitrogen and sulfur atoms in their structures. They are easy to be functionalized, have multiple modifiable positions, and are commercially available at cheap prices. The presence of N and S atoms makes them promising electron-donors [ 38 ]. WebWhen phenothiazine (2a) was added into the blank solution alone, 2a began to be oxidized at about 0.03 V. An obvious oxidation peak and a reduction peak appeared at 0.29 V and 0.11 V, respectively. ... The cross-coupling reactions were carried out smoothly without external oxidants and catalysts. The C–N bonds were constructed at a low ... WebThe Suzuki cross-coupling reaction of the mono boronate ester of phenothiazine PTZ with the corresponding bromo derivatives of phenyl BT generated the isomers p-PTZ, m-PTZ and o-PTZ.
