Visible and near-infrared fluorescent emitters are being applied in the medical imaging fleld. Examples include cancer diagnosis, ophthalmology, cardiac surgery and in the treatment of bums. (See also Chapter 4, section 4.6). 

The most important one is the efficient luminescence in the near infrared and the whole visible range. In addihon, PS is an active host for rare earth emitters, for example, Nd of Er, as well as dye solutions.

The emission color of PAVs depends crucially on the nature of the arylene unit. Replacement of a phenylene with an oligophenylene unit produces a blue-shift in the emission, e. g. the poly(pentaphenylene vinylene) 58 is a blue emitter (2rnax = 446 nm) [71], while heterocydes induce red-shifts. This is particularly marked in the case of thiophene so that the polymer 59 actually emits in the near-infrared (7m lx = 740 nm) [72]. The picture with fused polycyclic aromatics is more complicated with the 1,4-naphthalene 19 [73] and 9,10-anthracene 60 [74] polymers both being markedly red-shifted in emission compared with PPV (1), while the 2,6-napthalene 18 [75] and 3,6-phenanthrene 61 [58] materials are slightly blue-shifted.
