Abstract: | A series of homopolymers, poly(4-(benzoxazole-2-yl)phenyl)methyl methacrylate] (NAPH-PMABEs) containing benzoxazole side
chain and 1,8-naphthalimide end group, were prepared by atom transfer radical polymerization (ATRP) and end-group modification.
The structure of NAPH-PMABE was characterized by GPC, 1H-NMR and UV-vis spectra. The polymer has good solubility in common organic solvents, such as dichloromethane (CH2Cl2), tetrahydrofuran (THF), N,N-dimethylformamide (DMF), chloroform (CHCl3), acetone and toluene. The optical properties of NAPH-PMABE were investigated. Results show that NAPH-PMABE has a composite
emission spectrum comprising an ultraviolet component originating from benzoxazole side chains and a green component originating
from 1,8-naphthalimide end group in both solution and film. The intensity of the two emission bands can be easily tuned by
changing molecular weight.
