| Popis: | The E–Z isomerisation of two perchlorotriphenylmethane derivatives containing stilbene units has been investigated, both thermally and photochemically. The irreversibility of the E / Z isomerisation in both compounds is experimentally demonstrated and supported by density functional calculations. We thank Carlos Franco for his help with the HPLC analysis and Amable Bernab´e CTQ2016-80030-R for the MALDI-ToF characterizations.
