Abstract

Abstract: Ambient pressure chemical vapour deposition of 5, 5′‐bis((2‐(trifluoromethyl)phenyl)ethynyl)‐2, 2′‐bithiophene provides ultrapure needle‐shaped crystals. The crystal's supramolecular structure consists of an array of hydrogen bonds and π‐π interactions leading to anisotropic arrangements. The cyan emitting crystals exhibit an optical waveguiding tendency with guided polarised optical emissions due to anisotropic molecular arrangements. Abstract : Anisotropic molecular arrangement in 5, 5′‐bis((2‐(trifluoromethyl)phenyl)ethynyl)‐2, 2′‐bithiophene crystal waveguide triggers a polarized fluorescence.
