2-Phenyl-1,3-di(4-pyridyl)naphthvalene 3a was synthesized by the photoinduced reversible valence isomerization of 2-phenyl-1,3-di(4-pyridyl)naphthalene 2a. Then, 3a was converted into 3-phenyl-1,2-di(4-pyridyl)naphthalene 4a and 2a simultaneously. The t1/2 of 3a in DMSO-d6 at 90 °C was 2 h, while that at 110 °C was approximately 10 min.
2-苯基-1,3-二(4-吡啶基)naphthvalene 3A通过2-苯基-1,3-二(4-吡啶基)萘的光致可逆价异构合成2a中。然后,将3a同时转化为3-苯基-1,2-二(4-吡啶基)萘4a和2a。在90°C下DMSO- d 6中3a的t 1/2为2 h,而在110°C下约为10分钟。
