The channel inclusion compounds (ICs) formed by perhydrotriphenylene (PHTP) with linear or rod-shaped molecules can be used for investigations of guest-guest interactions and in optoelectronics applications, for which high dichroic ratios and high fluorescence quantum yields are desirable. The preparation and characterization of some novel PHTP ICs formed with oligophenylenevinplenes and substituted derivatives are described and the investigation of their optical properties is reported. Results of polarized fluorescence spectroscopy are shown to confirm the expected high optical dichroism.
