Mechanochromic luminescence (MCL) compounds exhibit change of their photoluminescent color in response to mechanical stimuli. The initial molecular alignment of a liquid-crystalline MCL compound was controlled by using an alignment layer. The rubbing method and rubbing direction were successfully determined. Influence of mechanical force on photoluminescent behavior was evaluated.
