[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

考虑到刚性共轭平面的Py2TTZ配体的强 π键的共轭效应以及中心金属离子的d10电子构型，化合物1和2可能表现出很好的荧光性质。因此对自由配体和化合物1和2的荧光性质进行了研究。如图S7所示，在固体状态下于413nm波长激发下，配体具有两个发射峰，分别在440nm和451nm。这归因于π*-π跃迁。（68-69引用文献？）粉末状态下的化合物1和2分别在414nm和417nm波长下激发，其发射峰分别在453nm和518nm。于自由配体Py2TTZ相比较，化合物1的发射峰有轻微的红移，这是由于配体的发射峰受金属干扰所致。然而，化合物2表现出了67nm很大的范围的红移，这是由于配体金属的电荷转移所致。
