Spin-crossover (SCO) metal complexes are expected to be widely used in data storage materials, display devices and sensors. Although a lot of spin-crossover photoswitches have been developed, the reversible photomodulation cases that work at room temperature are limited. Herein, a novel cobalt complex o-1-Co(II) wherein the salen unit bridges with bis-diarylethene has been designed as switch to construct “off-on” logic operation at room temperature The complex o-1-Co(II) displays an abrupt, reversible and hysteretic spin crossover (T1/2↓=166 K, T1/2←=177 K, and ΔT1/2=11 K) between the high-spin (HS) and low-spin (LS) states. Meanwhile, photocyclization of o-1-Co(II) with UV light produces a photoresponsive closed form c-1-Co(II), which always stays at low-spin without SCO at all. Moreover, the magnetic switching of the complex can also be achieved with redox reactions between Co(II) and Co(III). In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Application of 10243-15-9).
3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9) belongs to benzothiophene derivatives. Benzothiophene finds use in research as a starting material for the synthesis of larger, usually bioactive structures. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Application of 10243-15-9
