Abstract:

Big steric monomer with aggregation induced emission tetraphenylethylene group, norbornenyl modified with tetraphenyl ethylene(NTPE), was designed and synthesized, dendronized block copolymer poly(decanephenyl terephthalate based norbornene)-block-poly(norbornenyl modified with tetraphenyl ethylene)(PNDC-b-PNTPE) was prepared by sequential ring-opening metathesis polymerization(ROMP) of NTPE and dendronized monomer with di-decanyl groups, decanephenyl terephthalate based norbornene(NDC). One-dimensional photonic crystal(1D PC) thin film with both structural color and luminescent emission was prepared by thin film self-assembly. The experimental results showed that the 1D PC thin film, which reflects blue color, was prepared by quick self-assembly of PNDC-b-PNTPE in tetrahydrofuran(THF), the maximum reflection wavelength(λmax) was 443 nm. Scanning electron microscopy image of the cross section of the 1D PC thin film showed that the PNDC-b-PNTPE self-assembled into lamellar structures with periodicity of 133 nm. Fluorescent emission spectrum showed that the luminescent emission of the self-assembled 1D PC thin film was 425 nm. The 1D PC thin film with both structural color and luminescent emission shows potential in display and anti-counterfeiting fields.
