Abstract
Disclosed are compositions comprising at least one [benzo[4,5]imidazo(heterocycle)] compound, said [benzo[4,5]imidazo(heterocycle)] compound selected from the group consisting of structures I and II, wherein Rand Rare independently selected from the group consisting of a hydrogen atom, electron withdrawing group, organic group, divalent 1,2-cycloalkylidene group, or combinations thereof; 'q' is independently an integer from 1-4, L is a linking group, and 'r' is independently 0 or 1; said at least one [benzo[4,5]imidazo(heterocycle)] compound being present at a concentration sufficient to cause said composition to exhibit upon exposure to an excitation radiation having a wavelength of from about 330 nanometers to about 390 nanometers, a maximum fluorescence emission wavelength of greater than or equal to about 470 nanometers; and a Stokes shift of greater than or equal to about 80 nanometers; wherein the wavelengths are measured in bisphenol A polycarbonate matrix.
