Problem of definition
editThe definition of this term as "connections of molecules not through traditional bonds, but instead as a consequence of their topology" is not very good. It is OK for catenanes and borromean rings, but not for trefoil knots (which are single molecules) and not for rotaxanes (the topology of a rotaxane is the same than a ring plus a chain).Matrok2 (talk) 17:07, 9 January 2009 (UTC)
"Catenand effect" definition
editHi, from what I can tell the catenand effect refers specifically to the extra difficulty in removing a metal ion from a mechanically interlocked molecular architecture (MIMA) as compared to it it's non linked analogue. It is (from what I can see) not a general term used to describe enhanced stability of a MIMA. I came to this conclusion after cross referencing the book "The Nature of the Mechanical Bond: From Molecules to Machines" and the article "Chemical consequences of mechanical bonding incatenanes and rotaxanes: isomerism, modification,catalysis and molecular machines for synthesis" where the book seems to make it clear it specifically refers to extra difficulty in removing a metal ion the article does suggest that being the case however I feel there is a bit more ambiguity in it. Are all other editors on this page in agreement that it specifically refers to removing a metal ion? EvilxFish (talk) 16:27, 31 October 2016 (UTC)
molecular stitches
editHi folks! Somebody may be interested in mentioning the "molecular stitches" in plastic recycling from a chemist's (which I am not) POV. See http://newatlas.com/new-polymer-boost-plastics-recycling-cornell/48105/ and http://science.sciencemag.org/content/355/6327/814/tab-article-info and http://science.sciencemag.org/content/355/6327/797 I included a brief mention of it in plastic recycling. Chemists may have access to http://cen.acs.org/articles/95/i9/Welding-immiscible-polyethylene-isotactic-polypropylene.html?type=paidArticleContent which may have more info from a chemist's perspective.

- Hi, Will look into this and see if it is worth adding when I have more time (may be in a couple of months from now really am blocked up with work/other articles that need more attention unfortunately). Thanks for the suggestion. Regards EvilxFish (talk) 12:00, 19 March 2017 (UTC)
- @DennisPietras: Hi, I looked into the molecular stitches stuff. Seems quite interesting however I don't think it is relevant here. Mechanically interlocked molecular architectures can best be thought of as key chain loops where they cannot be separated unless you break a bond. From what I read it seems the molecular stitches are simply two different components woven around each other (like two threads), which therefore theoretically could be separated without the breaking of bonds (however in practice this may be difficult). That's my take on it anyway, a second opinion would be appreciated. EvilxFish (talk) 17:21, 18 April 2017 (UTC)
