Influence of solvent and solid-state environment on excited-state dynamics in donor-acceptor block oligomers.
Donor-acceptor π-conjugated block oligomers provide a platform for probing how molecular electronic structure and medium govern excited-state dynamics in π-conjugated systems. Here, we examine a series of diblock and triblock oligomers consisting of a tetrathiophene (T4) donor segment coupled to acceptor segments with...
