title: Phenylene ethynylene pentamers for organic electroluminescence.
abstract: An isomeric family of eighteen triisopropylsilyl-capped phenylene ethynylene pentamers (molecular formula C60H62Si2) has been prepared by using fast parallel synthesis, for organic electroluminescence. Each pentamer was grown on a polymer support of propylaminomethylated polystyrene by using a series of palladium-catalysed reactions between aryl iodides and alkynes. "Tea bag" technology was used to carry out several different reactions simultaneously in the same flask. Here I present the syntheses of the materials, compare their photoluminescence both in solution and in the solid state (amorphous thin films) and describe the incorporation of the most promising pentamer into organic electroluminescence devices.
