abstract = {X-ray free electron laser (XFEL) microcrystallography and
synchrotron single-crystal crystallography are used to
evaluate the role of organic substituent position on the
optoelectronic properties of metal–organic chalcogenolates
(MOChas). MOChas are crystalline 1D and 2D semiconducting
hybrid materials that have varying optoelectronic properties
depending on composition, topology, and structure. While
MOChas have attracted much interest, small crystal sizes
impede routine crystal structure determination. A series of
constitutional isomers where the aryl thiol is
functionalized by either methoxy or methyl ester are solved
by small molecule serial femtosecond X-ray crystallography
(smSFX) and single crystal rotational crystallography. While
all the methoxy examples have a low quantum yield $(0-1\%),$
the methyl ester in the ortho position yields a high quantum
yield of $22\%.$ The proximity of the oxygen atoms to the
silver inorganic core correlates to a considerable
enhancement of quantum yield. Four crystal structures are
solved at a resolution range of 0.8–1.0 Å revealing a
collapse of the 2D topology for functional groups in the 2-
and 3- positions, resulting in needle-like crystals. Further
analysis using density functional theory (DFT) and many-body
perturbation theory (MBPT) enables the exploration of
complex excitonic phenomena within easily prepared material
systems.},
