三環(3, 3, 1, 1^(3,7))葵烷之氮、磷、硼、鋁元素衍生物((CH_2)_6N_4,(CH_2)_6P_4,(CH_2)_6B_4及(CH_2)_6AI_4)理論計算研究

Theoretical Study of Tricyclo[3,3, 1,1^(3,7)] decane's Derivatives of N, P, B and AI, (CH_2)_6N_4, (CH_2)_6P_4, (CH_2)_6B_4 and (CH_2)_6AI_4

摘要


本研究以Gaussian 94程式組中之HF/6 -31G* ab initio分子軌域法對三環[3, 3, 1, 1 ^(3,7)] 英銳的IlIA族硼、鋁元素及VA族氮、磷元素衍生物((CH_2)_6M_4, M=N, P, B及AI)進行理論計算研究。由計算結果,吾人獲得上述各衍生物分子之幾何優選結構、游離能、HOMO、LUMO能量、能隙、生成倍、原子化熱以及按動頻率等數掉。證實(CH_2)_6N_4分子、(CH2)_6P_4分子、(CH_2)_6B_4分子及(CH_2)_6AI_4分子均為穩定的分子。同時藉由上述計算結果亦證實(CH_2)_6N_4分子及(CH_2)_6B_4分子較(CH_2)_6P_4及(CH_2)_6AI_4分子具有較高之穩定性,(CH_2)_6AI_4分子之導電性大於其他各衍生物分子之導電性。

The HF/6-31G* ab initio molecule orbital method from Gaussian 94 program package was applied to tricyclo[3,3,1,1^(3.7)]decane derivatives ((CH_2)_6M_4, M = N, P, B and AI). The structures, ionization potentials, HOMO, LUMO energies, energy gaps, heat of formations, atomization energies, vibration frequencies of these molecules were obtained. The results show that (CH_2)_6N_4, (CH_2)_6P_4, (CH_2)_6B_4, and (CH_2)_6AI_4 all are stable molecules with (CH_2)_6N_4 and (CH_2)_6B_4 molecules more stable than (CH_2)_6P_4 and (CH_2)_6AI_4 molecules. The (CH_2)_6AI_4 has the highest conductivity among the four derivatives.
