Implication

Experimental study demonstrates highly anisotropic fluorescence in mechanically sheared lyotropic perylene films, suggesting a straightforward route to ordered photoluminescent materials.

Key Points

To develop oriented solid thin films exhibiting polarized photoluminescence through the mechanical shearing and self-organization of a lyotropic liquid-crystalline dye.
Formulated a lyotropic liquid-crystalline phase using N,N‘-bis(N,N-diethylaminoethyl)perylene-3,4:9,10-bis(dicarboximide) dihydrochloride.
Applied mechanical shearing to the liquid-crystalline precursor to produce aligned solid films.
Mechanically sheared films exhibited highly anisotropic fluorescence emission.
Maximum photoluminescent emission intensity occurred when the film's shearing direction was perpendicular to the polarization axes of both excitation and emission light.
