An ABA triblock conjugated polymer with strong two dimensional quantum confinement of excitons was synthesized by self-assembly of two block conjugated polymers in binary blends
the heterostructures were prepared. The spatial confinement of excitons
and microphase separation as well as efficient energy transfer via interchain and intrachain mechanisms in the ABA triblock polymer heterostructures were shown by optical absorption
photoluminescence
and photoluminescence excitation spectra of the triblock polymer at room temperature.
