Baldo and coworkers [22, 23] were the first to use the red-emitting dye 2,3,7,8,12,13,17,18-octaethyl-21H,23H-porphine platinum (PtOEP, see Fig. 11.2) in an OLED. The absorption of this compound consists of a Soret band (at ca. 

However the reaction is rather complexfl233i and besides the use o-f the dangerous phosgene, the presence o-f the corrosive HCl creates several problems. Aliphatic isocyanates can be also obtained -from ole-fins with isocyanate ion in the presence o-f a salt or coordination compound o-f palladium or platinum 024], -from ole-fins with isocyan I c acid in the vapor phase over Pt/Al2O3025], and -from -formamides by oxidation over a silver catalystfl26]. However apparently these methods cannot compete with the phosgene route.
