Room temperature unstable macromolecule

[Edi]

What would it take to make a ... macromolecule, a group of atoms, molecules that has one "shared" electron, witch is at a very high energy level, so that room temperatures internal kinetic energy aka heat/ temperature and room temperature long IR waves would be enough to ionize it or, at least, take it to the conduction band?

You would need an organic polymer with alternating double bonds that is multiply substituted with electron donating groups. The electron donating ability of said groups to be determined. Length of the macromolecule should be approximately as long as the wavelength of the long IR electromagnetic radiation. The molecule should be fairly rigid to ensure that the overlap is maintained for the temperature of operation. (molecule should not flop around at room temperature, Tg >> RT)

So, it is possible. (?) Why don't we (can't we? ) develop this and use it to convert ambient heat and radiation in to electrical current?

[chemisttree]

You mean photovoltaics based on conducting organic molecules? (http://en.wikipedia.org/wiki/Organic_solar_cell) Or an organic thin film phototransistor? (http://www.eecs.umich.edu/omelab/downloads/MH%20IEEE%20TED%202004.pdf)

Hmm, so somethings actually being done at least along the lines of this.. Kinda.
Maybe someday we will actually have an ambient heat converter.. ( I really mean basically human body temperature, room temperature.. radiation coming of the walls and ground and what not. )
Its just that work is not done as fast as one would like.
Good. Kinda.
