Oxidation of carbynes : signatures in infrared spectra / E. Cinquanta, N. Manini, L. Ravagnan, L. Caramella, G. Onida, P. Milani, P. Rudolf. - In: THE JOURNAL OF CHEMICAL PHYSICS. - ISSN 0021-9606. - 140:24(2014 Jun 28), pp. 244708.1-244708.6. [10.1063/1.4884645]
Abstract:
We report and solidly interpret the infrared spectrum of both pristine and oxidized carbynes embedded in a pure-carbon matrix. The spectra probe separately the effects of oxidation on sp- and on sp(2)-hybridized carbon, and provide information on the stability of the different structures in an oxidizing atmosphere. The final products are mostly short end-oxidized carbynes anchored with a double bond to sp(2) fragments, plus an oxidized sp(2) amorphous matrix. Our results have important implications for the realization of carbyne-based nano-electronics devices and highlight the active participation of carbynes in astrochemical reactions where they act as carbon source for the promotion of more complex organic species.
