Energy migration processes

A new transduction mechanism based on the aggregation of conjugated sensory polymers induced ions as described by Swager et al. [109]. This new system displays enhanced sensitivity because of energy migration processes and has a high selectivity for over Na" ions. 

The objective of this review is to characterize the excimer formation and energy migration processes in aryl vinyl polymers sufficiently well that the excimer probe may be used quantitatively to study polymer structure. One such area of application in which some measure of success has already been achieved is in the analysis of the thermodynamics of multicomponent systems and the kinetics of phase separation. In the future, it is likely that the technique will also prove fruitful in the study of structural order in liquid crystalline polymers. 

ENERGY TRANSFER AND ELECTRONIC ENERGY MIGRATION PROCESSES... 

Photoinduced energy transfer and energy migration processes have been studied extensively in luminescent polymers for several decades and have applications in sensors, optics, and solar energy conversion [1-7], Energy transfer refers to a photophysical process whereby the excitation energy of an excited luminophore (donor D ) moves to a chromophore (acceptor A ). This process can occur by either... 

The photophysics of type I polymers is very similar to that of the corresponding small-molecule substituent chromophores that they contain. The polymer can be described as an inert scaffold that restricts the movement and relative distance of the chromophores. As a result, the photophysics of these polymers can be strongly affected by the conformation of the polymer backbone and, to a lesser extent, by the aggregation of the polymers. The basic photophysics and energy migration processes of this type of fluorescent polymers have been studied extensively by Guillet and Webber over the past two decades and have been summarized elsewhere [1,11].
