The effect of the third sulfur on the stability of the respective radical cations and radicals is examined computationally and experimentally in a laser flash photolysis study. A straightforward synthetic approach to a variety of 4-substituted trithiabicyclo[2.2.2]octanes from 3-bromo-2,2-bis(bromomethyl)propanol is developed, making a diverse set of mass-differentiated photolabile tags readily available
三噻吩双环[2.2.2]辛烷(TTBO)和羰基化合物的加合物经过有效的光诱导裂解,其量子产率可与二噻吩加合物相媲美。在激光闪光光解研究中,通过计算和实验研究了第三种硫对各个自由基阳离子和自由基稳定性的影响。开发了一种直接合成方法,用于从3-溴-2,2-双(溴甲基)丙醇中合成各种4-取代的三硫代双环[2.2.2]辛烷,从而使易于区分的多种质量分化的光不稳定标签可用于组合编码。
