Atomic structure of the continuous random network of amorphous C[(C6H4)2]2 PAF-1

We demonstrate that the amorphous material PAF-1, C[(C6H4)2]2, forms a continuous random network in which tetrahedral carbon sites are connected by 4,4'-biphenyl linkers. Experimental neutron total scattering measurements on deuterated, hydrogenous, and null-scattering samples agree with molecular dynamics simulations based this model. From MD model, we able for first time to interrogate atomistic structure. The small-angle is consistent Porod from particle surfaces, of form Q^{-4}, where Q vector. measure distinct peak at = 0.45 {\AA}^{-1}, corresponding sharp diffraction silica, indicates structural analogy between these two networks.
