Mass Spectrometry Evidence for Self-Rigidification of π-Conjugated Oligomers Containing 3,4-Ethylenedioxythiophene (EDOT) Groups using RRKM Theory and Internal Energy Calibration

Résumé

The self-rigidification of ionized π-conjugated systems based on two combinations of thiophene (T) and 3,4-Ethylenedioxythiophene (E) is investigated using mass-analyzed ion kinetic energy spectrometry (MIKES) of ions produced from electron impact ionization at 70 eV. The m/z 446 radical cations of the two isomers ETTE and TEET lead to detect m/z 418 and 390 daughter ions. The MIKE spectra differ only by the intensities of these fragment ions. As the m/z 418 daughter ion is produced through a same retro-Diels Alder reaction whatever
