visible-light. The para-methoxy group in 2 leads to a bathochromic shift in the emission band, pushing its tail further to the near infrared region. This group also changes the isomerization properties in 2, as it does not display the concentration-dependent isomerization rate change observed in 1, most likely because of a change in mechanism from rotation to inversion, and weaker π−π interaction in the
偶氮BF 2开关1和2及其扩展的菲啶基π系统具有红色荧光,其强度可以使用可见光进行光调制。的对位在甲氧基组2导致在发射带红移,进一步推动它的尾巴到近红外区域。该组还改变了2中的异构化性质,因为它没有显示1中观察到的浓度依赖性异构化速率变化,这很可能是由于从旋转到反转的机理变化以及系统中较弱的π-π相互作用。
