文摘
- •
Star-shaped molecules decorated with pyrene and anthracene exhibited aggregation enhanced excimer emission (AEEE).
- •
These star-shaped molecules emitted blue fluorescence and (IE/IM) ratio enhancement by increasing water fraction.
- •
Molecular mechanics (MM) showed flexible structure allowed an appropriate distance and conformation to form dimer.
- •
Transition Electron Microscopy (TEM) showed difference in particle size, shape, and distribution in different water fractions.
