title: Photochromism of a novel 6pi conjugate system having a bis(2,3'-benzothienyl) unit.
abstract: A novel photochromic molecule having a bis(2,3'-benzothienyl) unit has been synthesized. The derivative underwent a thermally irreversible photochromic reaction upon alternate irradiation with UV and visible light.
