    "abstract": "We demonstrate quantum interference for tetraphenylporphyrin, the first\nbiomolecule exhibiting wave nature, and for the fluorofullerene C60F48 using a\nnear-field Talbot-Lau interferometer. For the porphyrins, which are\ndistinguished by their low symmetry and their abundant occurence in organic\nsystems, we find the theoretically expected maximal interference contrast and\nits expected dependence on the de Broglie wavelength. For C60F48 the observed\nfringe visibility is below the expected value, but the high contrast still\nprovides good evidence for the quantum character of the observed fringe\npattern. The fluorofullerenes therefore set the new mark in complexity and mass\n(1632 amu) for de Broglie wave experiments, exceeding the previous mass record\nby a factor of two.",
