What Can Mathematical Chemistry Contribute to the Development of Mathematics?

Abstract: It is pointed out that visualization, such as the structural formula of molecules, is the most important factor in ‘chemical thinking’. How mathe-matical chemistry has contributed to the development of mathematics is de-scribed with particular reference to the topological index or Z-index, proposed by the present author, and fullerene chemistry developed by mathematical chemists in various countries. Mathematical chemistry will be able to contrib-ute to the development of mathematics by interplaying with mathematicians in the same way as it has been developing up to the present stage
