将螺苯并吡喃的苯溶液放入阳极氧化铝的纳米孔中，观察到光致变色特性的显著变化。在紫外线照射过程中出现的吸收峰向较短波长移动，并且脱色过程的衰减时间变得比原始溶液的衰减时间长约200倍。然而，经过几天的保存期后，吸收波长和衰减时间都恢复到原始溶液的吸收波长和衰减时间。这些实验结果表明，在氧化铝纳米孔的光致变色异构化的影响，而不是有限的自由体积的基质的大的表面积。
A notable change in the photochromic characteristics was observed when the benzene solution of spirobenzopyran was put in nanoholes of anodic alumina. The absorption peak that appeared in the ultraviolet irradiation process shifted to a shorter wavelength, and the decay time of the decoloration process became approximately 200 times longer than that of the original solution. After a preservation period of several days, however, both the absorption wavelength and the decay time recovered to those of the original solution. These experimental results suggest that the photochromic isomerization in the alumina nanoholes is affected by the large surface area of the matrix rather than the limited free volume.
