Thread: Looking for a material

I am looking for a material similar to water, but not water.

I was thinking in the nanotech area, to get polymer composite dots, that have the properties;

- Able to accept electrons.
- Able to accept and supply protons. (H+)
- Wants to keep oxygen to itself, but when a reaction pulls hard enough, oxygen should come off.
- Must be polar, in an extent it replicates water.

Why? I am preforming an experiment with anoxic reductions, and water interferes with this, only slightly, but i want to see how much the reaction changes when i pull out the negative effects water has on the reactions.

I hope any of you can help.

Thanks

Nobody?

I think everything accepts electrons. protons come with electrons i think. something that when you shake it it doesn't fizz up or bubble, as then oxygen is released. must be like water, must be a fluid.

How about ozone or o3?

Have you thought about studying chemistry before posting nonsense?

I know a little bit of this and that. he said he wants something that releases oxygen. maybe o4?

no you seem to know nothing. stop posting bullshit

Well.. Oxygen has none of those things i want in a material. I want a kind of complex polymer, where an oxygen atom can be drawn relatively easy. And i have to be able to regulate this by some means, like temperature, or by changing solvents, like varying my silicon oil. The problem with the demand is, water is really unique, and is extremely hard to replace.

O4 does not exist long enough to be detectable, it is a hypothetical byproduct when 2 O2 molecules collide under O3 creating conditions, (UV240).

My experiment Reduces FeS2 without the use of O2 (important), to Fe2+ and 2SO42-. This effect creates an electrochemical potential i can measure. (electrons leave the FeS2 part, and enter the solution, that's why the potential forms)

I don't know if it will work but the only polymer that leaps to mind that may have some of the properties you are looking for is PEG:

Polyethylene glycol - Wikipedia, the free encyclopedia

Hmm, that one looks like it's in the right direction. I like it's polarity, Soluble in methanol, ethanol, acetonitrile, benzene, and dichloromethane.

I'm only just finding out that my question is a lot harder than i first imagined. I'm actually asking for a potentially acidic/alkaline, solution, that conducts electricity, can work as a battery, and does not contain any water, and actually has the ability to reduce water by binding their oxygen and simply releasing a H+..

I wonder however how acidity will work without H3O+. Acidity will most probably not be measurable, but will it still act as an acid when it can easily release H+?

You will still get some dissociation which you can quantify by the pKa value. There is a comprehensive review of available data here. It might be worth having a dig through some of the papers listed, you may find a better option than PEG.

I have no idea if this is of any help to you, but I'll offer the following suggestion anyway: Polyaniline

But that doesn't contain oxygen so the requirement:

"- Wants to keep oxygen to itself, but when a reaction pulls hard enough, oxygen should come off."

can't be met.

I didn't really suggest polyaniline as a full solution to the problem, but rather as a substance with some seemingly desired properties that may provide an avenue for further exploration.

Some of those benzene rings could be harbor an oxygen group, but this won't come off easily, it could also have a COOH group for the proton release, not sure if this same group could be used to provide oxygen, as this won't come off as easily, water should never be formed in this reaction, but for the rest it should not matter.. Calculating oxidation rates for these types of organic substances is nearly impossible, all i can think off is testing some..

Bear in mind that the redox reaction also involves loss or gain of protons on the nitrogen atoms. Sulfonate groups on the benzene rings would perhaps be useful for producing a soluble polymer as well as changing the redox potential.
