The triplet-triplet annihilation of the lowest-lying excited states of porphyrins and phthalocyanines has been investigated by laser flash photolysis. Spectroscopic and kinetic evtdence indicates that the lowest-lying triplet dimerizes into excimers at a rate less than diffusion controlled.
## Abstract Tripletโtriplet annihilation (TTA) is studied in a wide range of fluorescent host:guest emitter systems used in organic lightโemitting devices (OLEDs). Strong TTA is observed in host:guest systems in which the dopant has a limited chargeโtrapping capability. On the other hand, systems i
