摘要：

A series of photochromic 6'-nitro-3-octadecylspirobenzoselenazolinobenzopyrans have been newly prepared and their solution structures of the colored form have been confirmed as 3-octadecylbenzoselenazolenium-2-trans- 1'-cis-(5'-nitrostyryl-2'-oxide) by selective partial deuteration and NMR techniques. Photochromic repetition of these compounds for 50 % fatigue attained the number more than ca. 800 times.
