Same for me. I know that theoreticallu something would be possible
using \Var and special typescripts, but I do not know how that is
supposed to be done in actual code.

This does not work well, because


is not correct.

(For educational purposes only, it cannot be used by
Mojca this way because of the staggered scripts)

Your macro has already parsed the argument. This way

   \def\molecule#1{{\activatelohi \scantokens{#1}}}

it would work (because \scantokens re-evaluates the argument).

And this way it does not need etex, nor the \gdef:

      \catcode`\_=\active \uccode`\~=`\_ \uppercase{\let~\low}%
      \catcode`\^=\active \uccode`\~=`\^ \uppercase{\let~\high}%
      \domolecule }%

It only gets the size right, not the boldnes. But it can be argued
that that is the correct behaviour anyways.
