Abstract:
Multicolor organic afterglow materials with lifetimes up to 2.65 s, a phosphorescence quantum yield of 27%, and excellent resistance to water, oxygen, and heat were achieved by grafting polyacrylamide onto poly(vinyl alcohol), incorporating arylboronic acid luminophores in situ, and constructing a locally ordered, densely hydrogen-bonded triplet-confining microenvironment in situ.
