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) .
