摘要：

In this paper, we investigate the catacondensed hexagonal systems with smaller numbers of Kekule structures. The unbranched catacondensed hexagonal systems with one kink are ordered. The unbranched catacondensed hexagonal system with two kinks and the branched catacondensed hexagonal system with one branched hexagon, which have the smallest and largest numbers of Kekule structures, are determined. Furthermore, based on the above results, the catacondensed hexagonal systems with the first up to the fourth smallest numbers of Kekule structures are determined. (C) 2003 Elsevier B.V.
