摘　　要：本文研究了酞菁分子结构与光存贮性能的关系，给出作用在酞菁薄膜上的激光功率和辐照时间，其阈值随酞菁分子侧链的增长而增加的特性。Homogeneous thin films of phthalocyanine compound were prepared by vapor deposition method and were found to be writable with He-Ne laser beam on phthalocyanine (MPc) films. The threshold irradiation time for writing the recording spots was 250 ns with He-Ne laser of 7. 8 mW power at the wavelength of 632. 8 nm. This indicates that the reflectance of MPc films is about 20% and the absorptance are falls in 550￣900 nm. The relationship between the structure and optical storage properties were discussed. The laser power and irradiation time increase as the in side chain phthalocyanine molecule increases.
