Here we describe the combination of an archetypal redox-active metal sulfide cluster, Fe4S4, with an organic linker, 1,4-benzenedithiolate, to prepare coordination polymers containing infinite chains of Fe4S4 cl

The invention provides a method for preparing sulfhydryl compounds by hydroxyl substitution and the sulfhydryl compounds. According to the method, low-cost and easily-obtained benzene or fused ring compounds with phenolic hydroxyl groups or benzyl hydroxyl substituents serving as raw materials to react with the raw materials such as inorganic sulfide under the catalysis conditions to prepare the corresponding sulfhydryl compounds. The method has the advantages that the preparation method is simple, convenient and rapid, low in cost, mild in reaction condition, high in reaction site selectivity and high in yield, a post-processing process is simple, and no pollution is caused.

A study involving the evaporation-grinding MALDI sample preparation method, MALDITOF/TOF CID, and Py-GC/MS is presented to examine the fragmentation mechanisms of poly(p-phenylene sulfide) (PPS). MALDI-TOF/TOF CID fragmentation studies yielded a wealth of information about the mass, structure (linear or cyclic), end-groups, and backbone modifications of the polymer. Additionally, Py-GC/MS experimental data are presented for comparison of the multimolecular free radical reactions in pyrolysis with the unimolecular fragmentation reactions of MS/MS.1,2 TOF/TOF CID results indicate that linear PPS undergoes random main chain fragmentation along the polymer backbone and preferentially fragments at bonds adjacent to dibenzothiophene and phenyl end-groups. Cyclic species produce fragment ions similar to linear species. However, the MS/MS precursor ions for cyclic PPS are, by far, the most intense peaks, while the precursor ions for linear species show relatively low intensity. CID fragmentation results are supported by Py-GC/MS data and are consistent with the proposed degradation mechanisms.
