Time‐resolved absorption spectroscopy measurements were performed to study the dynamics of photochromic 1,2‐Bis(2,4‐dimethylthiophene‐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, condensed ring by‐product formation is observed and hypotheses concerning the origin of this by‐product are presented.

光致变色全氟环戊烯二噻吩乙烯在溶液中的环化动力学和竞争过程。

进行了时间分辨吸收光谱测量，以研究光致变色的1,2-双（2,4-二甲基噻吩-3-基）全氟环戊烯（DMTPF）在氯仿中的动力学，包括反平行构象闭环反应和平行构象光物理。给出，讨论了所有特征时间，并将其与先前有关苯环取代的近分子的出版物进行了讨论。（Hamdi et al。，PCCP，2016）。除了预期的光环化过程外，还观察到缩合环副产物的形成，并提出了有关该副产物起源的假设。
