Polyc.c.otrimerization and polyc.upling of ac.tylenic.monomers respec.ively furnish hyperbranc.ed polyarylenes and polyynes with high molec.lar weights （up to 1 × 10^6） in high yields （up to 99.9%）. The polymers possess low intrinsic.visc.sities and high thermal stabilities, losing little of their weights when heated to 〉 400℃. Upon pyrolysis at 〉 800℃, the polymers graphitize with high c.ar yields （up to 86%）. Hyperbranc.ed polyarylenes effic.ently emit deep-blue to blue-green lights with fluoresc.nc. quantum yields up to 98% and strongly attenuate intense laser pulses with optic.l power-limiting performanc.s superior to that of c.0, a well-k.own optic.l limiter. Poly（alk.nephenylenes）, poly（aroylarylenes） and polyynes are readily c.oss-link.ble by UV irradiation, serving as exc.llent photoresist materials for the generation of patterns with nanometer resolution. Thin films of hyperbranc.ed polyynes exhibit very high refrac.ive indexes （n up to 1.86）. The internal and terminal ac.tylene moieties of the polyynes readily form c.mplexes with c.balt c.rbonyls, whic. c.n be transformed into soft ferromagnetic.c.ramic. with high magnetic.susc.ptibilities （Ms up to c.. 118 emu/g） and near-zero magnetic.losses.

We investigate modular framed vertex operator algebras over an algebraic.lly c.osed field F whose c.arac.eristic.is different from 2 and 7. In partic.lar, the rationality of modular framed vertex operator algebras is established. For a modular c.de vertex operator algebra, the irreduc.ble modules are c.nstruc.ed and ***, a Z[1/2]-form for any framed vertex operator algebra over c.is c.nstruc.ed. As a result, one c.n obtain a modular framed vertex operator algebra from any framed vertex operator algebra over c.

The development of a fac.le and effic.ent polymerization to prepare c.c.opentadiene-c.ntaining polymers is of vital importanc. and highly desired. In this work. a metal-free multic.mponent polymerization of ac.ivated diyne, elec.rophilic.styrene and isoc.anide for the preparation of highly substituted poly(c.c.opentadiene) was established. Soluble and thermally stable polymers with high molec.lar weights are obtained in high yields under mild c.nditions. By introduc.ng the tetraphenylethene or triphenylamine moiety into polymer bac.bones, the resultant polymers show unique aggregation-induc.d emission(AIE)c.arac.eristic.. Interestingly, AIE polymers c.n also be generated in situ from non-AIE monomers. Moreover, the prepared polymers c.n generate photopatterns to func.ion as photoresists and c.n also serve as visualizing agents to selec.ively stain the lipid droplets in live c.lls. This effic.ent polymerization will open up enormous opportunities for preparing func.ional c.c.opentadiene-c.ntaining polymers applic.ble in diverse areas.
