Self‐Assembled Alkynyl Azoles and Benzoazoles as Colored Optical Waveguides

Abstract

Abstract Different alkynyl azoles and benzoazoles have been synthesized in good yields by carbon‐carbon coupling reactions. The self‐assembly of some of these compounds by the slow diffusion technique led to well‐defined ribbons and needle‐like aggregates. The X‐ray study of some materials showed that the CH‐π interactions involving the C≡C triple bond and the heteroatoms induce aggregation along with H‐bonds due to the methoxy groups. A fluorescence and confocal optical microscopy study of most of the aggregates indicated optical waveguide behavior with different colors.
