[求助] 求大神帮忙翻译一下文献中的英文。用谷歌翻译的不是很懂已有3人参与

Considering the strong π-conjugated effect of the rigid coplanar
Py 2 TTz ligand and d 10 electron configuration of central metal ions, compounds 1 and 2 are likely
to exhibit good fluorescent properties. Thus, the fluorescent properties of free ligand and
compounds 1 and 2 were investigated. As shown in Figure S7, the free ligand Py 2 TTz exhibits
two emission peaks at 440 nm and 451 nm upon excitation at 413 nm in the solid state, which
can be assigned to π*-π transition. 68-69 Upon excitation at 414 nm for compound 1 and 417 nm
for compound 2, the emission peaks of compounds 1 and 2 in powder samples appear at 453 nm
and 518 nm, respectively. Compared with the free ligand Py 2 TTz, the emission peak of
compound 1 is slightly red shifted, which can be attributed to metal perturbed emission of ligand.
However, compound 2 displays a large red shift of 67 nm, which may be assigned to the ligand-
to-metal charge transfer (LMCT). 70-71

红外分析啊

这个我也能知道,就是那些峰具体只什么峰我没搞明白

由于存在共轭π键和中间有十个电子的配位键,成分1和2很可能存在荧光性质,在激发波长为413nm时,固体中成分1吸收峰440nm,成分2吸收峰451,推测为ππ共轭所造成,但是在分别用414nm激发成分1,417nm激发成分2,两个成 ...

谢谢你,看了你的,我应该基本上明白了

1的红移归功于金属离子移动,,2的红移则是因为配位体和金属间的电荷转移

谢谢
