摘要:

A series of novel bis-spironaphthooxazines (3a∼3i) and (4) containing a phosphoryl group were synthesized in 70∼91% yield. Their photochromic behaviors and photostabilty were investigated with the aid of absorption spectral measurements, showing that they exhibited higher fatigue resistance in the coloration and decoloration cycle than that of the parent reference compound1.
