| Description: |
International audience ; Time-resolved absorption spectroscopy measurements were applied to study the dynamics of photochromic 1,2-Bis(2,4dimethylthiophene-3-yl)perfluoro-cyclopentene (DMTPF) in chloroform including antiparallel conformer ring-closure reaction and parallel conformer photophysics. All characteristic times are given, discussed and compared to a previous publication concerning the close molecule substituted with phenyl rings. (Hamdi et al, pccp, 2016). Apart from the expected photocyclization process, a ring condensed by-product formation is observed and hypothesis concerning the origin of this by-product are presented. |
