2021 was an outstanding year for the detection of new astromolecules, with over three dozen newly discovered
species and several more tentatively identified. One of the first 2021 detections to be reported was
1-cyano-cyclopentadiene (c-C5H5CN), which was identified by
McCarthy and co-workers toward
TMC-1 using the
100m Green Bank Telescope.
As Michael McCarthy and Brett McGuire noted in a subsequent
article featured in the
Journal of Physical Chemistry A, the recent discoveries of 1-cyano-cyclopentadiene and
benzonitrile are marking the beginning of a new era of detections
involving organic compounds with one or more rings containing 5 or 6 carbon atoms. Identifications of
2-cyano-cyclopentadiene,
two cyanonaphthalene isomers,
cyclopentadiene,
indene
(see also here),
o-benzyne,
two ethynyl-cyclopentadiene isomers, and the
tentative detection of
ethynyl-benzene
followed just in 2021 so far.
