Benzo[b]thiophen-3-ylboronic acid (cas: 113893-08-6) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The electrophilic substitution of benzothiophene systems is much less regioselective than that of indoles. It is also used in the manufacturing of dyes such as thioindigo.Application In Synthesis of Benzo[b]thiophen-3-ylboronic acid

Herein we report on four diarylmaleimides based on 3- or 2-substituted benzothiophene (M3S or M2S) and benzofuran (M3O or M2O), which show very different emission properties: aggregation-caused quenching (ACQ), aggregation-induced emission (AIE), and dual-state strong emission (DSE) in both solution and solid states. Their emission color in the solid state can be adjusted from green-yellow into red. M2O displays strong red solid-state emission at 630 nm with a quantum yield of 46.3 %. Single-crystal X-ray diffraction anal. confirms that their large distinction in solid-state emission originates from their different packing structures: hydrogen-bonded organic frameworks (HOFs) for M3S, a staggered structure for M3O, J-aggregation for M2S, and weak H-aggregation for M2O. HOF of M3S and weak H-aggregation of M2O make them produce inverse-type piezochromic fluorescence: blueshifted “turn-on” and red shifted “turn-off” emission, resp. These results provide new insight in fluorescence manipulated by subtle structure modification. In the experiment, the researchers used many compounds, for example, Benzo[b]thiophen-3-ylboronic acid (cas: 113893-08-6Application In Synthesis of Benzo[b]thiophen-3-ylboronic acid).
