Research supported from National Science Centre (NCN) in Kraków, Poland (project 2019/35/B/ST5/00656).
The resarch guided in the framework of the project entitled "Development of new class of fluorophores based on boron centre with tailored photophysical properties" is focused on the optimization of the photophysical properties of fluorophores. More detailed data are available in published materials (listed below).

We have described a series of charge-transfer dyes to study the effect of halogen bonding on photophysical properties of those. For comparisons the models of acceptors and donor moieties were also studied.

The synthesis of dyes carrying two arms decorated with stron donors gave interesting properties, namemyl, one-photon absorption in the visible region, two-photon absorption in NIR and emission in NIR, biological transparent window.

The computational model for decompoistion of the energy was used to understand the character of interaction in halogen bonded complexes.

In the publication we have described how halogen bonding influences the photophysical properties of emitter. It turned out the lowering temperature had opposite to usual influence on emission, caused by greater complex stability when temperature was lowered. Open data LINK.
