Application

1,4-Phenylene diisocyanate (PPDI) can be used as:
  • A reactant to synthesize high yield polymers via criss-cross addition polymerization reaction with alkyl aldazines in pyridine.
  • An organic building block to prepare adamantyl-containing diurea and thiourea derivatives applicable as potent mammalian and human soluble epoxide hydrolase inhibitors.
  • A coupling agent to synthesize polyethylene glycol (PEG)/silica composite material using dibutyltin dilaurate (DBTDL) as a catalyst.

It can also be used:
  • As a cross-linking reagent to investigate the mechanism of enzyme immobilization on silanized surfaces.
  • In the synthesis of the dipodal bis-urea receptor, a selective receptor for hydrogen sulfate.
  • In the deposition of polyurea resists films via molecular layer deposition.

We investigated the mechanism of enzyme immobilization on silanized surfaces through coupling agents (cross-linkers) in order to understand the role of these molecules on interfacial processes and their effect on catalytic activity. To this end, we used a model multimeric

Metallic Li is considered as one of the most promising anode materials for next-generation batteries due to its high theoretical capacity and low electrochemical potential. However, its commercialization has been impeded by the severe safety issues associated with Li-dendrite growth.

A 3D urea-based porous organic polymer (Urea-POP) was prepared via the reaction of tetrakis(4-aminophenyl)methane and 1,4-Phenylene diisocyanate. The polymer was subsequently reacted with 2D layered nanosheets of graphene oxide (GO) to prepare Urea-POP/GO as a novel and highly efficient sorbent
