Although, current preparation methods for microporous organic polymers (MOP) based on coupling or condensations reactions are simple and flexible, they suffer from the requirement of additional modification steps for introducing properties for specific purposes. In the present work, we have developed a simple and rapid synthetic strategy to prepare MOP possessing reactive sites to incorporate any molecules of interest by ''Click Chemistry''. The clickable MOP with high surface area was readily synthesized through Schiff base chemistry using propargylated anthraquinone and melamine in the catalyst free, one-pot process. The versatility of the click coupling on the acetylene functional MOP was demonstrated on a model reaction using independently prepared fluorescent azido-pyrene.

“…The applicability of this kind of polymeric photocatalyst has been recently extended to the ATRP system. The required Cu(I) activator can be obtained from air-stable Cu(II) species via electrons released from mpg-C 3 N 4 under light (60,61). The photoinduced ATRP of a variety of vinyl monomers, including methyl methacrylate, methyl acrylate and styrene is investigated by using Cu(II)/PMDETA as the catalyst and mpg-C 3 N 4 as the photocatalyst in acetonitrile media.…”

Titanium dioxide (TiO 2 )/graphitic carbon nitride (g-C 3 N 4 ) composites were first used as photoinitiator for photochemically mediated controlled/living polymerization of methyl methacrylate. The polymerization was successfully carried out in polyethylene glycol at room temperature with FeCl 3 Á6H 2 O/N,N,N 0 ,N 0 ,N 00 -pentamethyldiethylenetriamine as complex catalyst and ethyl 2-bromoisobutyrate as initiator in this case. A pseudo-first-order dependence of the monomer concentration on the polymerization time was observed. TiO 2 /g-C 3 N 4 was verified to be an efficient photoinitiator. The polymerization was controlled to produce poly (methyl methacrylate) with narrow molecular weight distribution and controlled number average molecular weight (M n,GPC ). The M n,GPC matched well with the theoretical values when using both UV and sunlight irradiation as light source. The effects of reaction conditions on the polymerization were investigated. The polymerization could be started and stopped through periodically switching on/off the light. The living nature was further supported by the chain extension experiments.
