摘要：In this work, photostable coassemblies from a nonphotostable fluorene oligomer (the energy donor) and a photostable oligomer (the energy acceptor) are fabricated. Longrange exciton migration over a net distance of about 370
energy-donor molecules to energy acceptors is demonstrated in
such coassemblies. The fast and long energy migration allows
harvesting of the excitation energy of energy donors by
embedding a small number of energy acceptors for photostability enhancement. Importantly, embedding a small
number of energy acceptors in coassemblies causes a negligible
negative influence on the electron donation of energy donors
that are desired in practical applications. The advantages of the
coassemblies fabricated, that is, high photostability without
disrupting the electron donation of energy donors, are well
illustrated in fluorescence detection of trace explosives where
prolonged working life and improved detection capacity are
achieved.
