Luminescence dyes

Table 13-2. Chemical structures of representative small molecule transport materials ami luminescent dyes.

Red electrophosphorescent devices employing exciton blocking have been demonstrated.222 These devices contained the luminescent dye Pt(OEP)], doped into a 4,4 -/V, N dicarbazolebi-... 

Fluorescent encoded beads represent the largest group in multiplexed suspension arrays (Fig. 6c). Luminescent dyes are commonly incorporated by swelling. The... 

SUPRAMOLECULARLY ORGANIZED LUMINESCENT DYE MOLECULES IN THE CHANNELS OF ZEOLITE L ... 

Different types of sites exist. Those occupied with luminescent dye molecules are marked with small letters. Capital letters are reserved for traps that may or may not be luminescent. Per crystal, the number of sites available for dye molecules is imax and the number of sites available for traps is /lnax Equivalent v-sites have the same geometrical properties. Dye molecules in equivalent sites i are assumed to be equivalent. The same is valid for traps. 

Optical fluorescence microscopy is a powerful and sensitive method for obtaining information about the orientation of luminescent dye molecules in small crystals. In Figure 1.10, we show unpolarized and linearly polarized fluorescence of two perpendicularly lying zeolite L crystals loaded with DSC.
