Collaboration is a great idea! Can silicon cages be linked to singlet oxygen emission? A study by Prof. UAM Beata Dudziec, Dr. Joanna Szymkowiak, and Prof. UAM Tomasz Pędziński published in the prestigious journal The Journal of Physical Chemistry Letters (MNiSW=200, IF=4.8) shows that yes, they can.
The researchers developed a synthetic pathway for hybrid salphen compounds with T8 cages at their periphery, using solution-based and mechanochemical methods for Zn²⁺ ion coordination. The study revealed intriguing photophysical properties of these systems, influenced by their aggregation behavior. Additionally, their ability to generate singlet oxygen (¹O₂) was examined, highlighting the role of excited-state dynamics in their emission properties and potential applications in medicine and materials science.
