时间分辨单光子计数技术被用来比较和对比线性聚（己基甲基硅烯），聚（己基硅炔），和三个共聚物纳入标称1%，5%和25%己基硅炔分支点的发光行为。虽然低水平的支化导致电子吸收光谱的相对较小的变化，但对发光行为的影响是惊人的
Time-resolved single photon counting techniques were used to compare and contrast the luminescence behavior of linear poly(hexylmethylsilylene), poly(hexylsilyne), and three copolymers incorporating nominally 1%, 5%, and 25% hexylsilyne branch points. While low levels of branching cause relatively small changes in the electronic absorption spectrum, the effect on the luminescence behavior is striking
