The efficiency of di-Me iodoterephthalate (I-DMT), 2,6-di-Me 1-benzoylnaphthalate (BZN), and 2,6-bis(2-hydroxyethylthio)naphthalene (NSEG) at quenching the fluorescence of the poly(ethylene 2,6-naphthalenedicarboxylate) (PEN) matrix has been investigated by steady-state and time-resolved fluorescence spectroscopy. All three quenchers are capable of capturing the energy migrating between naphthalene dimers. Steady-state fluorescence data indicate that, after the quencher has trapped the migrating energy, the excited quencher can relax either via nonradiative processes (I-DMT) or via radiative processes (BZN and NSEG). Fluorescence decay measurements show that NSEG quenches PEN fluorescence best, followed by BZN, and I-DMT is the worst quencher. Quenching efficiency of a given quencher increases linearly with quencher concentration, for quencher contents below the overlap concentration, for which the entire polymer matrix is covered by quenchers. Above the overlap concentration, quenching efficiency increases at a slower pace because any addnl. quencher quenches an already quenched volume Our exptl. results could be interpreted by compartmentalizing the quenching process in the polymer matrix. Compartmentalization could be handled by a blob model, which was applied to quantify the quenching efficiency of I-DMT and BZN.
