Circular dichroism and circularly polarized luminescence triggered by self-assembly of tris(phenylisoxazolyl) benzenes possessing a perylenebisimide moiety

Chiral tris(phenylisoxazolyl) benzenes possessing a perylenebisimide moiety assembled to form helical stacks. The self-assembling behavior of the helical stacks responded to changes in solvent properties, temperature, and concentration. Strong circular dichroism (CD) and circularly polarized luminescence (CPL) of their assemblies were displayed, and were controlled by external stimuli.
