My Flashcards

Definition

Meaning

A compound where fullerene (C60 or other fullerenes) acts as a negatively charged ion, typically forming salts with metals.

A class of chemical substances derived from fullerenes, where the fullerene molecule has gained electrons and exists as an anion, often complexed with alkali or alkaline earth metals, and studied for unique superconducting or electronic properties.

Linguistics

Semantic Notes

Exclusively used in chemistry and materials science. The term is a specific, systematic chemical nomenclature, not used metaphorically. Always refers to a chemical structure, not a process or a concept.

Examples

By Part of Speech

adjective

British English

  • The fulleride phase was characterised by X-ray diffraction.
  • They studied the fulleride properties at low temperatures.

American English

  • The fulleride phase was characterized using XRD.
  • They investigated the fulleride properties under high pressure.

Examples

By CEFR Level

B2
  • Scientists created a new material called a fulleride.
  • Fullerides are special salts made from carbon molecules.
C1
  • The superconducting transition temperature in alkali metal fullerides like Cs3C60 is pressure-dependent.
  • Research focused on synthesising and characterising the novel barium fulleride compound.

Learning

Memory Aids

Mnemonic

Think: "Fullerene" + "-ide" (like chloride, bromide). A fullerene acting like a halide ion.

Conceptual Metaphor

A 'cage' (the fullerene) that has trapped extra electrons, becoming a negatively charged building block.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not translate as 'фуллерИд' (incorrect). The standard Russian term is 'фуллерид' (fullerid). Beware of false cognates with 'фторид' (fluoride).

Common Mistakes

  • Misspelling as 'fullerite' (a different material). Confusing it with 'fullerene'. Using it as a verb (e.g., 'to fulleride').

FAQ

Frequently Asked Questions

No, it is a highly specialised term used only in advanced chemistry and materials science.

No, it is exclusively a noun referring to a class of chemical compounds.

A fullerene is a neutral molecule (like C60). A fulleride is an ionic compound where a fullerene has gained electrons to become a negatively charged anion.

Primarily in condensed matter physics, solid-state chemistry, and advanced materials science research, particularly in studies of superconductivity.
