and phenanthrene‒like derivatives have been synthesized, in 46%‒67% overall yields, through a short and practical photochemical pathway involving soft conditions and very low-cost starting materials. The target π‒conjugated systems have been characterized by 1H, 13C and COSY NMR and FT−IR spectroscopies. The absorption properties of these compounds have been explored experimentally in various solvents
通过涉及软条件和极低成本起始材料的短而实用的光化学途径,合成了多种新型功能性菲和类菲衍生物,总收率为 46%∼67%。目标 π- 共轭系统已通过1 H、13 C 和 COSY NMR 以及 FT-IR 光谱进行了表征。这些化合物的吸收特性已经在各种溶剂中进行了实验探索,显示出完全在紫外光谱 (λ max = 281−285 nm),同时确定了吸收带形状的微小变化。这些化合物表现出蓝移或红移发射,导致量子产率为 0.07 至 0.21。还通过循环伏安法研究了它们的电化学性质,以强调对此类物质的不可逆氧化还原活性过程,并评估 HOMO 和 LUMO 能级,这使得电化学带隙 ( E g–el ) 在 2.34 eV 至 2.80 eV 之间。
