You are using bibstyle=chem-acs, which means that the citation style is unchanged from the biblatex default. You probably want the chem-acs citation style too, which is much easier to do using style=chem-acs:
\begin{filecontents}{\jobname.bib}
@article{James2003,
author = {James, S. L.},
journal = {Chem. Soc. Rev.},
number = {5},
pages = {276--288},
title = {{Metal-organic frameworks}},
volume = {32},
year = {2003}
}
@article{Rowsell2004,
author = {Rowsell, Jesse L.C. and Yaghi, Omar M.},
journal = {Microporous Mesoporous Mater.},
pages = {3--14},
title = {{Metal-organic frameworks: a new class of porous materials}},
volume = {73},
year = {2004}
}
@article{Allendorf2009,
author = {Allendorf, M. D. and Bauer, C. A. and Bhakta, R. K. and Houk, R. J. T.},
journal = {Chem. Soc. Rev.},
number = {5},
pages = {1330--1352},
title = {{Luminescent metal-organic frameworks.}},
volume = {38},
year = {2009}
}
\end{filecontents}
\documentclass[12pt,a4paper,bibliography=totoc]{scrreprt}

\printbibliography
\end{document}
This automatically sets sorting=none and sortcites=true as that is standard for chemistry styles.
First thing to do is to add a field for the journal abbreviation to the article entrytype, journalabbr in the MWE. Therefore you need to declare a datamodel (an extra file; in the MWE I've used filecontents to simulate that) and you have to tell biblatex/biber to use it in the package options.
Then you have to modify the cite command, so it fits your needs. \citep from the authoryear-style (your citestyle) uses the \cite command. There you just have to add a switch, which checks if the field journalabbr is empty or not, and prints it out or not.
Last but not least you have to add the abbreviation fields to the entries.

Just use the following redefinition of
\supercitewith just\bibopenbracketand\bibclosebracketsprinkled in.If you replace the
\superciteabove by\citeyou redefine the standard\citecommand.
