摘要：

Exposing a uniformly aligned discotic columnar liquid crystal to an argon ion laser beam results in a reorientation, thereby changing the optical properties of the liquid crystal. We have studied this new optical storage effect for a polymer dispersed metallomesogenic compound which exhibits a columnar phase at room temperature. The writing energy is approximate to 3.5 J cm(-2). The stored information can be erased by heating and subsequent shearing of the sample.
