| The Topological Index Z Before and After 1971 (2008) | |||||||||||||||
Abstract | |||||||||||||||
| The author’s first paper on the topological index Z was published in Bull. Chem. Soc. Jpn. in 1971, where good correlation was found between the boiling points of alkane isomers and their Z values. This idea is based on the author’s unpublished work performed in 1957, when the boiling points of octane isomers were predicted by scrutinizing the structural dependency of boiling points of alkanes up to heptane. Behind stories inside and outside of the country before and after the birth of Z index are introduced. Several academic encounters of the author and reactions of the contemporary chemists to the new idea are also described. In the end some aspects of QSAR problems for octane isomers are introduced. | |||||||||||||||
