The interchain hopping transport can be described by the probability Ql(x) -where x is the effective conjugation or delocalization length-of finding a comparable mean free path on another chain weighted by the Frank-Condon factor FC. The conductivity a can then be described as a function of the concentration C of polarons, multiplied by the integral over the interchain hopping probability Pp(x) [96, 97]. [Pg.35]

As shown in this review, the properties of polyphenylene-based materials, so as to maximise their potential as active materials in LEDs or polymer lasers, can be controlled by dehberate synthetic design. By incorporating bridges between some or all of the phenylene units to make ladder or stepladder polymers the effective conjugation length of the polymer may be controlled, while the interactions between the chains and the injection of charges may be regulated by careful selection of substituents. By these means it is possible to minimise interchain interactions, which lead to loss of luminescence... [Pg.73]
