fluoride to obtain its nido-[C2B9] − species; the reaction with fluoride to obtain nido-[C2B9]− species was also performed for biphenyl- and bithiophene-fused o-carboranes, the synthesis of which we have previously reported. The structures and optoelectronic properties of the three carboranes and their nido-[C2B9]− species were experimentally and theoretically characterized. The nido-[C2B9]− species possessed
联芳基稠合的闭合碳- ö -carborane与苯基噻吩基部分被合成并与氟化反应,获得它的巢- [C 2乙9 ] -物种; 我们还对联苯和联噻吩稠合的邻-碳硼烷进行了与氟化物的反应,以得到Nido- [C 2 B 9 ] -物种,我们先前已经报道了它们的合成。三种碳硼烷及其nido- [C 2 B 9 ] -的结构和光电性能物种进行了实验和理论上的表征。由于富含电子的阴离子物种,因此Nido- [C 2 B 9 ] -物种具有较高的HOMO和LUMO能级。他们还显示了电荷转移(CT)过渡带,并且在结晶态和溶液态都观察到了有效的CT发射,这是因为在Nido- Carbane笼中的碳-碳键长度较短,并且抑制了碳-碳键振动。
