[求助] 英文段落翻译

本人英语水平有限,不是很明白下面段落是什么意思,望哪位帮忙翻译下,谢谢!
Theoretical calculations performed by Honeybourne on closed-shell conjugated macrocyclic ligands placed in perfectly linear columnar stacks, with an interplanar spacing of 0.373 nm, pointed out that both metal-free phthalocyanines(酞菁) and hemiporphyrazines(半紫菜嗪),because of the large bandgaps, must show low ó values at room temperature when undoped, i.e., they will not act as intrinsic semiconductors. However, these results are extremely distance-dependent,
and narrower bandgaps and larger bandwidths could be obtained by reducing the interplanar distance. Moreover, by taking into account the fact that the conductivity of the macrocycles is usually very low until donor-acceptor interactions occur, the studies were extended to open-shell (radical ions) systems.
The calculations for two spacing distances (0.373 and 0.332 nm) showed that the metal-free phthalocyanine displays larger bandwidths and narrower bandgaps
than the corresponding hemiporphyrazines(半紫菜嗪). Indeed, the H2Thp radical anion does not have at 0.373 nm the minimum bandwidth required to ensure enough mobility of the charge carriers.

Honeybourne进行理论计算指出,闭环大环共轭配体很好的嵌在线性柱状堆叠(一种晶胞堆叠方式?),面间距是0.373纳米;无金属配基的酞菁和半紫菜嗪,由于它们具有大的能带隙,在无掺杂的情况下必然表现出低欧姆值,也就是说它们不会充当精密的半导体。然而,这些结果都是极其依赖距离的,通过减小晶面距可以获得窄能带隙和大的频宽。此外,考虑到的大环化合物的电导率通常是非常低的,除非体 - 受体发生相互作用,研究扩大自由基离子系统。
两个晶面距离(0.373和0.332 nm)的计算表明,无金属酞菁(比相应的hemiporphyrazines半紫菜嗪)显示更大的带宽和窄能隙。事实上,H2Thp的阴离子自由基没有在0.373纳米所需的最小频宽,以确保电荷载体足够的流动性。
