  • On the Nature of Nonplanarity in the [N]Phenylenes
    作者:Daniel Holmes、Sriram Kumaraswamy、Adam J. Matzger、K. Peter C. Vollhardt
    DOI:10.1002/(sici)1521-3765(19991105)5:11<3399::aid-chem3399>3.0.co;2-v
    日期:1999.11.5
    The [N]phenylenes display marked deformation from planarity in the crystalline state. In order to probe the generality of this phenomenon, several derivatives were synthesized and their single-crystal X-ray structures were obtained. All new compounds displayed some degree of nonplanarity. Thus, for example, the parent triangular [4]phenylene (4b) has a median bend angle at the ring junction of 1.5 degrees and a range of 0.3 degrees to 3.5 degrees, whereas hexakis[triisopropylsilyl(ethynyl)] triangular [4]phenylene (4c) possesses the bulkiest appendages and the largest median bend angle and range (3.8 degrees and 1.7 degrees-5.6 degrees, respectively). A detailed analysis of the bending and twisting angles at the ring junctions, however, revealed that the magnitude of deformations were independent of topology, molecular size, and substituent type. In contrast to the phenylenes, a Cambridge Structural Database (CSD) search of unsubstituted and non-peri-substituted naphthalenes and anthracenes shows these molecules to be virtually planar in the solid state. A comparison of the single-point energies (HF/6-31G*) of the phenylenes with the acenes calculated for molecules possessing a fixed bend angle at the ring fusion of 3 degrees, 6 degrees, 9 degrees, and 12 degrees reveals the former to be 26% to 45% easier to deform than the latter. Based on these results, the nonplanarity seen for the phenylenes is most likely a consequence of crystal-packing forces deforming particularly flexible molecules.
