Abstract
Theoretical and experimental results are presented for a variety of novel phases of carbon. These include (1) `opalized forms' of diamond and graphitic foams, which we have prepared as cubic phases having lattice periodicities of several thousand angstroms, (2) `rectangulated carbon phases' in which hexagonal ring sheets are coupled together to form cyclobutane rings, whose predicted properties and structural features are consistent with available data for a high-pressure-formed phase of carbon which graphizes at room temperature, (3) hinged carbon phases that are ferroelastic and have negative linear compressibilities and negative Poisson's ratios, and (4) a hexagonal acetylenic carbon phase and related polytypes, whose predicted diffraction data and properties are consistent with reported data for controversial carbon phases called carbynes.
