Effective Shielding of Triplet Energy Transfer to Conjugated Polymer by Its Dense Side Chains from Phosphor Dopant for Highly Efficient Electrophosphorescence

摘要

To examine the quenching of a triplet exciton by low triplet energy (E_T) polymer hosts with different chain configurations for high E_T phosphor guests, the quenching rate constant measurements were carried out and analyzed by the standard Stern-Volmer e
