首次提出并运用&取代基模型&(即将金属原子视为四唑环上的取代基、对金属配合物的处理采取与计算衍生物完全相同的模式)较为简便地计算研究了系列四唑金属配合物的热解反应，发现开环形成叠氮化物的活化能与它们的实验撞击感度之间存在良好的线性关系。

The B3LYP/6-31+G level of theory and the polarizable continuum model are employed to study the binding interactions between amidinium and tetrazolate anion which have two binding modes (side-on and end-on) as well as the binding interaction between amidinium and formate anion. We find, in the gas phase, that the end-on acetamidinium tetrazolate is more stable with its interaction energy 3.56 kJ/mol higher than that of the side-on.

The POSS-based hybrids were characterized by FTIR,~1H-NMR,~(29)Si-NMR and UV. The POSS content in the hybrids were determined using three kinds of different methods and could be effectively controlled by varying the POSS feed ratio.4. It was estimated that about 5~8 vinyl groups in POSS participated in the copolymerization reactions by the ~1H-NMR spectra.
