Facile synthetic routes to a new class of red α-benzo-fused BOPHYs with 6,5,6,6,5,6-hexacyclic fused rings and β-thiophene-fused BOPHYs with 5,5,6,6,5,5-hexacyclic fused rings are presented. These dyes were characterized by NMR spectroscopy, HRMS, X-ray structure analysis, cyclic voltammetry, and optical measurements. Compared to parent BOPHY, significant red-shifts in the absorption (up to 600 nm
轻松合成具有6、5、6、6、5、6-六环稠合环的新型红色α-苯并稠合BOPHY和具有5,5、6、6、5、5的β-噻吩稠合BOPHY的简便合成路线给出了-六环稠合环。这些染料通过NMR光谱,HRMS,X射线结构分析,循环伏安法和光学测量来表征。与母体BOPHY相比,发现它们的吸收(溶液中高达600 nm)和发射(溶液中高达648 nm,固态高达717 nm)有明显的红移,并且具有很高的化学稳定性和光稳定性。芳香环稠合的BOPHY染料。如循环伏安法和DFT计算所示,芳环稠合导致HOMO能级显着提高,从而使π共轭比这些BOPHY染料有效扩展。
