What is it about?

BODIPY chromophores are composed of a functional-COOH group at meso position were synthesized and investigated photophysically and theoretically. The experimental results showed that BODIPY compounds with iodine atoms lead to intersystem crossing (ISC) process. According to the theoretical results, the charge transfer in the investigated compounds mostly appears to be intrinsic local excitations, corresponding to high photoluminescence efficiency

Why is it important?

In this research, the ISC rates are found as 150 ps and 180 ps for iodine BODIPY compounds with and without π-expanded biphenyl moieties, respectively. The experimental findings are useful for the design and study of the fundamental photochemistry of organic triplet photosensitizers.


Discovering the photophysical properties, especially in femtosecond time window, of new organic molecules is considerable exciting and therefore, writing this article was a great pleasure for me. I believe this article work will be useful to researchers working on novel derivatives to find out about triplet photosensitizers.
