Neighbor Effect in Complexation of a Conjugated Polymer
Charge-transfer
complex (CTC) formation between a conjugated polymer and low-molecular-weight
organic acceptor is proposed to be driven by the neighbor effect.
Formation of a CTC on the polymer chain results in an increased probability
of new CTC formation near the existing one. We present an analytical
model for CTC distribution considering the neighbor effect, based
on the principles of statistical mechanics. This model explains the
experimentally observed threshold-like dependence of the CTC concentration
on the acceptor content in a polymer:acceptor blend. It also allows
us to evaluate binding energies of the complexes
