Design and synthesis of well-defined hetero-functional cubic silsesquioxane remain as international research focuses and challenges. In this work, we demonstrated in detail the synthesis of two Janus hetero-functional cubic silsesquioxane. We applied similar "bottom-up" method to construct the aimed Janus HFCSQ, which was carried out by using cyclic tetrasiloxanes as synthetic platforms and followed by further hydrolysis and cage-closure. The obtained products exhibited good solubility in THF, CHCl3 and DMSO, which embodied themselves potential use in further derivations and processing. The precise structure of these obtained Janus HFCSQ were fully characterized by FTIR, 1H NMR, Maldi-tof MS, 29Si NMR, WAXD and TGA. Red-shifts observed from Photoluminescence UV-vis analysis further confirmed extended conjugation of the silsesquioxane cages, which in turn proved the formation of completed cages.This work provided us a versatile novel method to prepare the resulting Janus HFCSQs, which can widely expand the species of silsesquioxane monomers and applications as well.

Key words: hetero-functional cubic silsesquioxane, Janus nanoparticle, functional monomer
