The influence of distinct side-chains (Figure ) and linkers (Figure ) was evaluated based on the average stabilization rates over OE-4mer ligands sharing these components. Bulkier side-chains tend to destabilize the perovskite lattice, with ethyl showing the lowest stabilization rate (76.76%) followed by methoxy (84.50%). Despite their increased size, fluorine (92.16%) and cyano (91.38%) substitutions exhibit marginally increased average stabilization rates relative to unsubstituted analogues (90.50%). The overall side-chain trend is weakly correlated with the distribution of ∆⟨σ 2 ⟩ for each class of sidechain (Figure ), reflecting the increased strain associated with the side-chains with lower stabilization rate. In contrast, the length of the linker bears no simple relationship with the stabilization rate (Figure ). The shortest linker, 1C, shows the lowest stabilization rate (67.39%) followed by 3C (76.70%). Comparing 3C with its double-bonded analog, 3C-conj (85.73%), suggests that the additional planarity increases stability. The 2C linker, which is by far the most represented in contemporary experimental literature, is among the most stable (94.83%) but is still outperformed with respect to stability by the ether containing linkers, 2C-O (98.93%) and 3C-O (97.14%). These ether linkers present a potential avenue for incorporating otherwise promising ligand bodies into perovskites that fail with the more typical 2C linker. At this stage, we have not considered the relationships between the stabilization rate and the optoelectronic properties of these ligands. It may be that some linkers with lower overall rates, like 3C-conj, still lead to favorable packing with specific bodies that promote charge transport or other favorable properties.
