摘要：
A pi-conjugated polymer containing an azobenzene segment in its backbone is found to be highly photo-responsive. As the polymer film is irradiated with an interfering laser beam, the trans-to cis-photo-isomerization in the polymer chain induces a great change to the chain configuration from a rigid-rod to an irregular coil, and a corresponding great local stress, which drives the chain transfer to form high contrast surface patterning.
