摘要： Structured phosophorescence with 20μs life time[480nm, 510nm (max),550nm] from 4-phenyl-benzophenone (4-PBP) was quenched by trieyhylamine (TEA) in benzene. An Anomalous exciplex emission with strutureless peaking at 647nm and 30μs life time. A quenching mechanism has been shown to involve a mixed (π,π*) and (n,π*) triplet of 4-PBP to form an exciplex with the grond state of TEA.
