Ag. Mirochnik et al., "Antenna effect" in macromolecular complexes of Eu3+ dibenzoylmethanate with poly(acrylic acid) containing chromophoric groups, POLYM SCI B, 42(9-10), 2000, pp. 271-272
Fluorescent properties of Eu3+ dibenzoylmethanate macromolecular complexes
with poly(acrylic acid) containing grafted o-phenathroline groups were stud
ied. Examination of the luminescence spectra of the polymer suggests the ex
istence of the effective intramolecular transfer of excitation energy from
the resonance levels of chromophoric groups to Eu3+ (the "antenna" effect).
The intensity of luminescence for the complex with a low content of Eu3+ (
[Eu3+] = 0.75 wt %) and a 2% content of phenanthroline groups is higher by
an order of magnitude compared to europium poly(acrylates).
