Room Temperature Phosphorescent Crystals Consisting of Cyclized Guests and Their Uncyclized Mother Host Molecules
A unique strategy for the fabrication of room temperature phosphorescent guest/host crystals, which consist of pi-extended cyclized guests and their mother uncyclized flexible brominated hosts, is reported. Combinations of bisbenzofuropyrazines/bis(2-bromophenoxy)pyrazines are the examples. Judicious choice of the guest/host pair allows to create highly phosphorescent crystals.
