资源简介:
We report an anthracene-based Ni-MOF [Ni­(II) metal–organic framework, {[Ni­(μ2-L)2Cl2]·x(C6H6)·y(MeOH)}n (1), L = anthracene-9,10-diylbis­(methylene)­diisonicotinate] whose crystal structure reveals the presence of hexagonal channels with a pore size of 1.4 nm that can accommodate guests such as C60 and C70. Both confocal fluorescence and Raman microscopy results are in agreement with a homogeneous distribution of fullerenes throughout the single crystals of 1. Efficient energy transfer from 1 to the fullerenes was observed, which emitted partially polarized fluorescence emission. Stronger binding between 1 and C70 versus C60 was confirmed from HPLC analysis of the dissolved material and provides a basis for the selective retention of C70 in liquid chromatography columns packed with 1.
