摘要:
The C(60)ONCFn cycloadduct (Fn=ferrocene) was prepared in the reaction between C-60 and ferrocene oxime, the ferrocene derivative was bound to C-60 at the 6-6 bond by a heterocyclic oxygen-nitrogen-carbon ring; the compound was stable in air. The compound dissolved in dichloroethane was deposited on HOPG and observed by UHV STM/STS methods. The molecules of C(60)ONCFn formed several-microns-long straight chains with clearly visible adducted groups pointing to one side of the chain. The STM/STS observations are discussed within the terms of semiempirical quantum chemical molecular modeling. (C) 2003 Elsevier Science B.V. All rights reserved.
