Intermolecular Foerster's energy transfer in labeled poly[N-(2-hydroxypropyl)methacrylamide].
By copolymerization of monomers containing donor (carbazole) and acceptor (dansyl) fluorophores withN-(2-hydroxypropyl)methacrylamide (HPMA), statistical copolymers with "low" and "high" contents of the fluorophores were prepared. The increase in nonradiative energy transfer between copolymers with a low content of fluorophores was probably due to intermolecular penetration of the polymer coils in concentrated solutions.
