Discotic liquid crystals are an interesting type of organic semiconductors that allow
the actual implementation of discotics in devices.
In the present work we study thin films of hexapentyloxytriphenylene, known as HAT5 for short (Scheme 1), a historically important discotic molecule which allowed the proof of photoconductivity in discotic LCs [13]. Besides exhibiting high charge
