Abstract

The invention relates to a monodisperse laser-responsive photoinducedly-movable one-dimensional organic semiconductor microbelt which can convert luminous energy into mechanical energy at a microscopic scale so as to make other things work, and a preparation method and application thereof. The one-dimensional organic semiconductor microbelt is obtained through self-assembly of a plurality of perylene bisimide derivatives having same substituents at two ends and containing 3,4,9,10-perylenetetracarboxylic dianhydride in virtue of pi-pi interaction among 3,4,9,10-perylenetetracarboxylic dianhydride. In the absorption wavelength range of a construction monomer molecule and under irradiation by laser with laser intensity density of greater than or equal to 40 mW/cm2, the one-dimensional organic semiconductor microbelt continuously moves on the surface of a hydrophobic substrate under excitation, and the moving manner of the microbelt is directly related to the structure of construction monomers composing the one-dimensional organic semiconductor microbelt while the moving speed of the microbelt is directly related to provided laser intensity density. Thus, the moving manner of the one-dimensional organic semiconductor microbelt can be controlled by adjusting the structure of construction monomers composing the one-dimensional organic semiconductor microbelt.
