用蒸发法制备了由长链螺吡喃组成的有机薄膜。这些膜在环境气氛中立即或逐渐结晶。研究表明，长链烷基的引入是获得透明光滑薄膜的有效途径，并且在薄膜中发生了可逆的光致异构化，即一种开关。
Organic thin films consisting of spiropyrans with long alkyl chains were prepared by evaporation. These films crystallized immediately or gradually in an ambient atmosphere. It has been demonstrated that introduction of long alkyl chains is an effective way to obtain transparent and smooth films by evaporation and that reversible photo-isomerization, a kind of on-off switching, is performed in the films.
