Figure 7. (A) Synthesis of chiral cross-linked polymers of PDVB and PMBA via radical polymerization of divinyl monomers around biphenyl group-bearing SiO₂ nanofibers. (B) ¹³C NMR spectra of L-form Bp-SiO₂, DVB@Bp-PEI@SiO₂ and isolated PDVB. Solid-state CD and UV-vis absorption spectra of (C) chiral isolated PDVB and (D) TCPP@PDVB.

DVB: Divinylbenzene; MBV: N,N′-methylenebisacrylamide; PDVB: polydivinylbenzene; PMBA: poly(N,N′-methylenebisacrylamide); NMR: nuclear magnetic resonance; CD: circular dichroism; TCPP: tetrakis(4-carboxyphenyl)porphyrin.
