metadata.value: The luminescent and excitation spectra of polycrystalline triptycene doped by diphenyl and triazole
  have been studied. In triptycene—diphenyl systems sensitized luminescence was observed
  when the excitation of the matrix (triptycene) led to luminiscence of the energy acceptor — the
  dopant. For the latter system the maximum luminescence of the donor and that of the excitation
  band of the energy acceptor differ by 10 nm, unlike the triptycene—triazole system where
  differences amount to 75 nm and the sensitized luminescence was not detected. This result is
  consistent with the notion that effective electronic excitation energy transfer occurs in systems
  with the greatest overlap of the emission spectrum of energy donor with the excitation spectrum
  of the acceptor. The IR study of triptycene films deposited at 77 K reveals irreversible structural
  changes upon raising the temperature indicating a possible effect of recrystallization on the
  luminescence spectra. Refs 12. Figs 7. Tables 1.
