studied organic chromophores is presented. The luminescence properties of a series of symmetrical sulfur-bridged chromophores are reported as a function of the oxidation state of the bridging sulfur atom. The photoluminescence quantum yield is significantly enhanced by successively oxidizing the sulfur bridge from sulfide (S), to sulfoxide (SO), to sulfone (SO2).
提出了一种提高几种广泛研究的有机发色团发射量子产率的一般方法。据报道,一系列对称硫桥接发色团的发光特性是桥接硫原子氧化态的函数。通过将硫桥从硫化物 (S) 依次氧化为亚砜 (SO) 和砜 (SO2),显着提高了光致发光量子产率。
