• process is called Compton scattering [179]. One of the major purposes of radiation modification of polymer surfaces is grafting. The surface grafting can be simply tuned by the dose of radiation [180]. Radiation grafting on polymer surfaces is also compatible with RDRP for high density and well-defined

• functionalization. Controlled surface grafting with a well-defined β-CD dimer is, on the other hand, expected to address these issues and allow for the preparation of a homogenous surface exhibiting well-defined divalent binding sites. To meet this objective, a novel method for the facile synthesis of a β-CD dimer

• inclusion of 2,6-ANS into both cavities of the β-CD dimer. Surface grafting The β-CD dimer was grafted onto quartz slides activated for CuAAC using an in-house method for the preparation of azidosilane monolayers (unpublished results) involving vapor deposition of 3-glycidoxypropyltrimethoxysilane (GPTMS

• intensity of the solution exhibited a four-fold enhancement. A 14 nm blue-shift was also observed (Figure 7). Fluorescence from 4 persists after several centrifugation/washing cycles (which completely remove 4 from the solvent) and the band shape does not undergo further change, thus proving the ZnO surface

• grafting. Conclusion Derivative 4 involving both the fluorophore moiety and the carboxylic group capable of binding the ZnO surface can serve as an efficient molecular probe owing to the high sensitivity to the polarity of the surroundings. Derivative 2 can also be used when fluorescence detection at
