From Polymer to Monomer: Cleavage and Rearrangement of Si‐O‐Si Bonds after Oxidation Yielded an Ordered Cyclic Crystallized Structure

Abstract: Polymerization reactions are very common in the chemical industry, however, the reaction in which monomers are obtained from polymers is rarely invesitgated. This work reveals for the first time that oxone can break the Si-O-Si bond and induce further rearrangement to yield an ordered cyclic structure. The oxidation of P1, which is obtained by reaction of 2,2'-1,2-ethanediylbis(oxy)bis(ethanethiol) (DBOET) with 1,3-divinyl-1,1,3,3-tetramethyldisiloxane (MM(Vi)), with oxone yielded cyclic crystallized sulfone-s… Show more

“…The ligand field splits the 3 d orbital of the Si atom, which is degenerated before coordination. The electrons are rearranged in the split orbitals, and d–d transitions occur, which could be inferred to be responsible for the luminescent properties of C1 . Second, as a good emitter, VPD also emits a blue color upon irradiation with UV light.…”

“…3d orbitals of Si atoms were split by ligand fields, which degenerated before coordination. Electrons then rearranged in split orbitals, and d–d transition occurred, coinciding with results of our previous work . Existing blue emissions indicated that novel silanes may be potentially applied as blue emission materials in OLEDs …”

“…Then, the electrons rearranged in the split orbitals resulting in a d–d transition, which could account for the luminescent properties of Cns-non . 29 , 30 Dns-non were transparent and presented strong red photoluminescence under natural light with the incorporation of rhodamine-B [ Fig. 1(e) and (f) ].…”
