It should be merged.

Above statement is unsigned. I disagree with a merge. Graphynes are distinct from graphene (and carbon nanotubes, for example) in that they have different bond hybridization, and thus is a distinct carbon allotrope. Swc nice (talk) 01:30, 18 August 2012 (UTC)[reply]

I disagree with a merge. Graphyne and graphene are two distinct allotropes of carbon. Graphynes can be mentioned in graphene section, but a seperate page should be dedicated to graphynes with appropriate links. — Preceding unsigned comment added by 78.185.217.16 (talk) 00:16, 27 January 2013 (UTC)[reply]

I Strongly disagree with merging. Graphynes are distinct materials with different mechanical and optical properties. — Preceding unsigned comment added by 139.179.65.8 (talk) 12:52, 29 January 2013 (UTC)[reply]

Graphdiyne synthesized?

[edit]

I checked reference 14 (the nature article "Homo-coupling of terminal alkynes on a noble metal surface"), and it doesn't claim the synthesis of graphdiyne. See figure 3, for example, where they show what they really synthesized: a dimer of 1,3,5-triethynyl-benzene, and in figure 5, polymers of 1,3,5-tris-(4-ethynylphenyl)benzene. Note that these still include hydrogen atoms, and are NOT a polymorph of carbon (meaning, only carbon). Also, it's not the same structure (only three carbon atoms of the six-ring connected, compared to all six for graphdiyne). Citing the conclusion of the paper: "This provides a new synthesis route towards conjugated molecular nanosystems and networks, providing potential for the fabrication of regular 1D scaffolds, such as carbyne40,41, 2D polymers, such as graphyne or graphdiyne6,42, and similar hydrocarbon membranes." I.e., they showed potential, not actual graphdiyne.

Unfortunately, reference 17 ("Study of carrier mobility of tubular and planar graphdiyne") is only a theoretical study, and the sentence "The construction of nanotubes of graphdiyne was reported few years ago[17]" is wrong.

I will remove these from the main article. —!nnovativ (talk) 08:36, 2 July 2018 (UTC)[reply]

Ref. 13 (Li et al., 2010, Architecture of graphdiyne nanoscale films) does explicitly mention graphdiyne synthesis and includes SEM, TEM, and AFM images. So perhaps the lede's "Although not yet synthesized" could be altered. --Ingafube (talk) 22:21, 22 March 2019 (UTC)[reply]
