摘　　要：聚并苯同系物的导电性与其结构之间关系的研究是理论化学的活跃领域之一 .用聚并苯同系物的能量、电子极化率和同系序数分别表征其稳定性、导电性和结构参数 ,经研究发现 ,聚并苯同系物的能量、全价电子极化率 (a)和π电子极化率 (aπ)以及π电子极化率占全价电子极化率的比例 (aπ/a(% ) )与同系序数 (N)之间满足同系线性规律 .One of the very brisk filed of the theory chemistry is that studies on the relation between the conductivity and their structure of polyacene homologue.The stability,connectivity and structure parameter of polyacene homologue is characterized by their energy,electronic polarizability and homologous number respectively.The study has found that a set correlation equation is contented with the energy,the polarizability of total and π electrons,the ratios(%) of the π electronic polarizability to the total electronic polarizability of polyacene homologue and homologous number (N) .
