after immersing in DMF for 24 h and 30 min respectively. The
shape of cross-linked spheres keeps perfectly but the un-cross-
linked spheres collapse into the fragments fully. This result
confirms the high stability of the cross-linked shell originated
from photo-cross-linking reaction.

The porphyrin moieties of the hollow sphere are reserved
after etching treatment with DMF. From the UV–vis spectra
of the cross-linked hollow spheres after DMF etching, the
obvious absorption peak at 424 nm indicates the reservation of
porphyrin groups (Spectra can be found in the electronic
supplementary information (ESI){).
Conclusion
In conclusion, a new photosensitive copolymer P(DSS–VP)
has been synthesized and used to self-assemble (SA) with
TAPP (or THPP) on quartz wafer (2D SA) and on styrene
copolymer (or SiO2) beads (3D SA) in a weak basic condition.
The core–shell composite spheres with [P(DSS–VP)/TAPP
(or THPP)]n films as shell have been prepared. The driving
force of SA between [P(DSS–VP) and TAPP (or THPP) is
identified to be H-bond interaction. The photosensitive multi-
layer films can be stabilized by UV irradiation. The hollow
spheres with cross-linked P(DSS–VP)/TAPP film as shell were
prepared and demonstrated that they were very stable towards
polar solvents.
