Functionalized poly（phthalazinone ether sulfone ketone） was synthesized by successive chloromethylation and azidation, followed by curing reaction with the propargyl end-groups of various molecular weight crosslinking agents in the presence of Cu（I） catalyst via the azide-alkyne click reaction. The influences of the chain length of crosslinking agents on the poly（phthalazinone ether sulfone ketone） system were studied. FTIR and DSC tests demonstrated certain crosslinking by azide-alkyne reaction with the formation of triazole ring. DSC results showed that curing temperature shifted to lower temperatures considerably in the presence of Cu（I） catalyst. TGA showed cured polymers were of much higher thermal stability, including higher thermal decomposition temperatures and higher char-yielding properties. After being cured, the polymers became insoluble in organic solvents and the gel fraction of the cured polymers exceeded 71%. Wide-angle X-ray diffraction results indicated there was a short distance order in the poly（ether sulfone）（PES） main chain except for the azido methyl poly（phthalazinone ether sulfone ketone） and 4,4＇-bis（2-propynyloxy） biphenyl （AMPPESK-BP） system.

Hydrogen sulfide(H2S) is commonly referred to as the third gasotransmitter with firmly established physiological roles. Prodrug approaches have been broadly applied to deliver H2S for various applications and mechanistic studies. Since S-persulfidation and glutathionylation are known to be important in cellular signaling by sulfur species, there have been interests in developing donors of persulfide and glutathione persulfide as well. In this review, we discuss the recent development in area of prodrugs for various sulfur species.
