The extent of electronic coupling between a boron dipyrromethene (BODIPY) fluorophore and a diarylethene (DAE) photoswitch has been modulated in a covalently linked mol. dyad by irradiation with either UV or visible light. In the open isomer, both moieties can be regarded as individual chromophores, while in the closed form the lowest electronic (S0→S1) transition of the dyad is slightly shifted, enabling photomodulation of its fluorescence. Transient spectroscopy confirms that the dyad behaves dramatically different in the two switching states: while in the open isomer it resembles an undisturbed BODIPY fluorophore, in the closed isomer no fluorescence occurs and instead a red-shifted DAE behavior prevails. In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8Application In Synthesis of 2-Methylbenzo[b]thiophene).
2-Methylbenzo[b]thiophene (cas: 1195-14-8) belongs to benzothiophene derivatives. Benzothiophene is used as starting material for the synthesis of bioactive molecules. The core structure is a part of various pharmaceutical substances and natural products. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.Application In Synthesis of 2-Methylbenzo[b]thiophene
