The random copolymers grafted onto the surfaces of SiO_2 hollow sphere via reverse atom transfer radical polymerization(RATRP) and “click” chemistry were investigated.A sufficient amount of peroxides,as initiating moieties,were introduced onto the surface of hollow spheres.Then styrene and 4-vinylbenzyl azide were polymerized via surface-initiated reverse atom transfer radical polymerization(Sl-RATRP) using the peroxide group modified hollow sphere as initiator,resulting in hollow spheres(HS) with grafted polystyrene-co-poly(4-vinylbenzyl azide) copolymer brushes as(HS-g-PS-co-PVBA) intermediate material.Subsequently,N-propargyl-carbazole(PC) was covalently bonded to HS-g-PS-co-PVBA by the “click” reaction,resulting in the HS-g-PS-co-PVBPC hybrid material.The excitation spectrum is dominated by a broad band from 350 nm to 400 nm with the maximum peak at 362 nm,attributed to the characteristic absorption of the carbazole group of HS-g-PS-co-PVBPC hybrid material.

Substituted, N-propargyl- carbazole was covalently bonded to HS-g-PS-co-PVBA by the “click ” reaction , resulting in the HS-g-PS-co-PVBPC hybrid material. The excitation spectrum is dominated by a broad band from 350 nm to 400 nm with the maximum peak at 362 nm, attributed to the characteristic absorption of the carbazole group of HS -g-PS-co-PVBPC hybrid material.
