Delayed Luminescence of Organic Mixed Crystals. VII. Intermolecular Triplet Decay Processes

摘要

Mixed single crystalline specimens of various hosthyphen;guest systems have been studied. Host materials were biphenyl, durene, and phenanthrene; guest materials were naphthalenehyphen;hsandds, phenanthrenehyphen;d10andh10, and chrysene. Primary attention was paid to the temperature dependence of firsthyphen;order guest phosphorescence decay rates. It has been shown that the guest triplet depletive route is intermolecular and that it involves a thermally stimulated processT1Grarrw;T1H. No other temperaturehyphen;dependentT1Gdepletive process of any significance has been detected.
