Two types of processing exist for T1-T2* data sets. The simplest option is to process all the data assuming the transverse magnetization decays are exponentials. This type of processing is simple and is commonly employed in relaxation correlation measurements such as T1-T2. The Schlumberger program employed is user-friendly and only requires a few parameters to be manually changed. We utilized this method to process the results in figures 1 and 2. The disadvantage is that many rigid samples, like many of our solid samples, display non-exponential gaussian or sinc-gaussian T2* decay curves (SM, see section S3). The sinc-gaussian nonexponential T2* decay in the time domain occurs due to a distribution of Pake doublets in the frequency domain. Processing non-exponential decay curves as exponential curves will introduce errors and harm quantification. However, the work of Guo et al. demonstrates that the plots using this approximation yield similar relaxation time values to the non-exponential processing results. Exponential processing is a suitable method for species identification and differentiation, but it is not suitable for quantification of the samples. This is further supported in figure where we compare exponential and non-exponential processing of ZIF-8 synthesis where the exponential processing peaks are very similar to the graphs generated from the non-exponential processing method (SM, see section S4).
