Abstract

Dendrimeric and related molecules that have the same atomic connectivity from exterior to core, P-C1-J1-C2- ⋯ Z (P peripheral group, J juncture, C connector, Z core) can be described completely by a highly compact fractal notation, which is of the general form PfJ1,J2⋯ (C1.C2 ⋯ )Z. In this paper, we show how to describe molecules that deviate slightly from the symmetry of a related parent molecule, by use of parenthetic expressions (iX), (dX), and (YrX) which designate atoms or molecular groups that are inserted, deleted, or replaced by other groups in the parent. © 1998 John Wiley & Sons, Inc.
