【摘要】 在共混的两种低维聚合物量子线中,采用分子自组装技术制备了嵌段低维聚合物纳米线的异质结构,通过对室温下吸收光谱、发光光谱和激发光谱的研究,证实了在这种嵌段低维聚合物纳米线的异质结构中存在很强的激子限域效应以及链内和链间的能量传递效应。更多还原

【Abstract】 An ABA triblock nano-line of low dimension polymer heterostructures with strong two-dimensional confinement of excitons was synthesized by self-assembly of two block conjugated polymers in binary blends.The spatial confinement of excitons as well as efficient energy transfer via interchain and intrachain mechanisms in the ABA triblock nano-line of low dimension polymer heterostructures were shown by optical absorption,photoluminescence,and excitation spectra of the triblock polymer at room temperature.更多还原
