Further picosecond PL studies on dendronized PFs show that the fluorene-based emission in dilute solution follows a single exponential decay, whereas those in thin film decayed in a multi-phase manner and the lifetime prolongs with the generation of dendronization. These observations are discussed in terms of dispersive transport happening between adjacent chains in film. The dispersive relaxation can be controlled by site isolation of bulky dendrons. Our results prove that dendronization is highly effective in controlling the inter-chain interactions of fluorene-based polymers.
