T. Nagasaki et al., SYNTHESES AND CHARACTERIZATION OF PHOTOCHROMIC DENDRIMERS INCLUDING A1,3-ALTERNATE CALIX[4]ARENE AS A CORE AND AZOBENZENE MOIETIES AS BRANCHES, Chemistry Letters, (8), 1997, pp. 717-718
The first photochromic dendrimers which involve a 1,3-alternate confor
mer of a calix[4]arene as a core and azobenzene skeletons as branches
have been synthesized and characterized. Photochemical properties of t
he photochromic dendrimers are described.
