摘要
Efficient room temperature phosphorescence is observed in natural compounds and polymers such as starch,cellulose,bovine serum albumin(BSA),and some other carbohydrates.Whereas being practically nonluminescent in solutions and TLC plates,they emit bright phosphorescence in the crystalline states with lifetime up to microseconds,exhibiting crystallization-induced phosphorescence(CIP)characteristics.The CIP of these natural products without any conventional chromophores offers a new platform for the exploration of conceptually novel luminogens.
Efficient room temperature phosphorescence is observed in natural compounds and polymers such as starch, cellulose, bovine serum albumin （BSA）, and some other carbohydrates. Whereas being practically nonluminescent in solutions and TLC plates, they emit bright phosphorescence in the crystalline states with lifetime up to microseconds, exhibiting crystallization-induced phosphorescence （CIP） characteristics. The CIP of these natural products without any conventional chromophores offers a new platform for the exploration of conceptually novel luminogens.
