Photoinduced tuning of (anti)aromaticity and associated mol. properties is currently in the focus of attention for both tailoring photochem. reactivity and designing new materials. Here, we report on the synthesis and spectroscopic characterization of diarylethene-based mol. switches embedded in a biphenylene structure composed of rings with different levels of local (anti)aromaticity. We show that it is possible to modulate and control the (anti)aromatic character of each ring through reversible photoswitching of the aryl units of the system between open and closed forms. Remarkably, it is shown that the irreversible formation of an annulated bis(dihydro-thiopyran) side-product that hampers the photoswitching can be efficiently suppressed when the aryl core formed by thienyl groups in one switch is replaced by thiazolyl groups in another. This study involved multiple reactions and reactants, such as 2,5-Dimethylthiophene (cas: 638-02-8Related Products of 638-02-8).
2,5-Dimethylthiophene (cas: 638-02-8) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The core structure is a part of various pharmaceutical substances and natural products. It has been used as a raw material for the synthesis of biologically active structures and is found in pharmaceuticals such as leukotriene synthesis inhibitors and antifungals, as well as in many natural products.Related Products of 638-02-8
