Femtochemistry of Guest Molecules Hosted in Colloidal Zeolites (original) (raw)

This research explores the femtochemistry of guest molecules, particularly 2-(2¢-hydroxyphenyl)benzothiazole (HBT), incorporated within colloidal zeolites like FAU and MFI. The study presents insights into the ultrafast photophysical and photochemical processes occurring within these host materials, demonstrating that the confined environment facilitates exciting optical properties. A significant finding includes the ultrafast deprotonation of HBT initiated by UV excitation, providing valuable implications for applications in fluorescent sensors and molecular switching.
