چکیده انگلیسی
When the rotor-stator compound C60â
C8H8 is treated at temperatures above about 450 K under high-pressure conditions, fullerene-based copolymers are formed. Earlier results have shown the existence of two types of polymers, a “low-pressure” pseudo-cubic copolymer similar to that formed at atmospheric pressure, and a “high-pressure” phase tentatively identified as a pseudo-orthorhombic copolymer structurally based on the known low-temperature phase. In this communication we show that the reaction boundary between the polymers occurs at pressures near 1Â GPa. From this result it follows that the slope of the cubic-orthorhombic phase line in the pristine material is 305Â KÂ GPaâ1, significantly larger than the slope observed for the corresponding rotational transition in pure C60.
