The Merrifield-Simmons index is one of the popular and valuable topological indices in chemistry molecular graph theory.In order to calculate the Merrifield-Simmons index of polyphenyl chains fast and convenient,the formulae of the Merrifield-Simmons indices of three special polyphenyl chains Zn,Sn and Ln were obtained by using recurrence method.After some matrix operation,the more general formuale on the Merrifield-Simmons index of the three polyphenyl chains are given.
