TECHNOLOGY FOCUS - ELECTRONICS - Preferred Device: The device further comprises a hole transport layer containing an electroactive material having functional groups selected from carbazole, amine, and/or triarylamine; an electron transport layer containing an electroactive material having functional groups selected from fluorene, pyridine, and/or phenylpyridine; a substrate selected from plastic, glass, and/or metal; and a layer selected from an abrasion resistant layer, an adhesion layer, a chemically resistant layer, a photoluminescent layer, a radiation-absorbing layer, a radiation reflective layer, a barrier layer, a planarizing layer, and/or an optical diffusing layer.    TECHNOLOGY FOCUS - METALLURGY - Preferred Components: The organic phosphorescent dye has at least one transition metal selected from iridium, platinum, osmium, rhenium and ruthenium.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composite: The composite further comprises an organic initiator. Preferred Method: The method for preparing an organic composite further involves adding at least one organic initiator into the solution of step (c). The solution of step (c) is treated with heat or radiation to covalently bond the organic phosphorescent dye to the electroactive material. Preferred Components: The electroactive material is a crosslinkable composition of an epoxy, and/or acrylate; and it has at least two functional groups. EXAMPLE - Vinyl-iridium (III) bis((4,6-difluorophenyl)-pyridinato) picolinate (vinyl-FIrpic) (8 mg) was dissolved in tetrahydrofuran (THF) (1.6 ml) to form a solution of FIrpic (0.5 wt.%). SR454 (RTM: ethoxylated trimethlopropane triacrylate) (33 mg) was dissolved in tetrahydrofuran (THF) (3.3 ml) to form a acrylate solution (1 wt.%). The Vinyl-FIrpic (0.5 wt.%) in THF solution (0.020 ml) was mixed with acrylate (l wt.%) in THF solution (1 ml). The mixture solution was drop-cast onto a quartz substrate and ultraviolet (UV) cured for one minute and baked at 110 degrees C for five minutes to give an acrylate conjugated vinyl-FIrpic film.
