Electronic structure and properties of bunz' polymers

摘要

The bunz polymers consist of n-membered rings of carbon atoms connected via n mono- or diethynyl units (m=1, 2 respectively) to other such rings. Coordinated to the three-, four, and five-membered rings are ML_N units (L=CO, Cp) which lead to 18-electron rule stability at each metal-organic center.
