The spectroscopic and electrochemical studies suggest the energy structure of this class complex can be easily controlled by modification. With the introduction of electron-donating arylamino groups, the obtained complexes show intense and continuous absorption bands in the region of 250-550nm with strong metal-to-ligand charge transfer dπ(Pt →π* transitions (ε~ 2×104 dm3 · mol-1 · cm-1). Complexes involving the construction of D-π-A type systems also display continuous absorption bands in the region of 400-750nm, rising from the overlapping effect of MLCT and LL'CT bands.

In order to clarify the rules of POD isoenzyme in the hazelnut, identify their blood relations between female, male and filial generations and select the superior parents for cross-breeding, we have studied the characteristics of peroxidase isoenzyme which are distributed in the 34 hazelnut varieties or lines by polyarclamide gel electrophoresis, The results showed that:POD isoenzymes of Corylus heterophylla Fisch, Corylus avellana L, and the hybrid of Corylus heterophylla Fisch × Corylus avellana L had obvious difference; some hybrids had lost P10 spectrum band of parents; the enzyme spectrum of 32 hybrid hazelnuts produced 'new hybrid spectrum bands'that could be considered as a mean to identify hybrids.

为了阐明过氧化物同工酶在榛品种中的分布规律，探讨平榛、欧榛及其杂种榛之间的亲缘关系，选育优势杂交亲本，本试验采用聚丙烯酰胺凝胶垂直电泳，研究了34个榛品种成熟叶过氧化物酶同工酶酶谱特征，结果表明：平榛、欧榛及其平欧杂种榛品种间酶谱具有较大差异；有的杂种品种遗失了父母本共有谱带P10；32个平欧杂种榛品种出现了双亲所不具有的新酶带，可作为鉴别杂种的一条途径。

Moreover, it added two bands of higher molecular weight and one band which molecular weight is about 25KD, but lost two bands of smaller molecular weight. The bands of peroxidase isozymes showed vitrous plantlets lost three bands such as Rf0.245, Rf0.309, Rf0.382; but added one band of Rf0.200, and the activity of Rf0.136 was increased.
