Recent experiments [158] on polymer light emitting diodes using alkoxy derivatives of PPV as the semiconducting and luminescent material have demonstrated that the ratio of the EL quantum efficiency (ihel) to the PL quantum efficiency (t]pl) can be increased to t1el/ 9pl>0 5, well beyond the theoretical limit for singlet and triplet excitons as the low energy excited states. 

Conjugated polymers have found widespread applications in semiconducting devices and fluorescent sensing schemes. They are now incorporated as emitter layers into commercially produced polymer light-emitting diodes (PLEDs). What makes conjugated polymers alluring ...
