Nor for that matter can I claim to be expert over the wide range of chemical behavior which he explored in his research so diligently and productively. Still, even in the short time that I interacted with him, this altoget

The Preparation of Ribose-Free ‘Artificial Dinucleotides’: A New Approach to Molecular Recognition?ribose-free system to be prepared and characterized in which molecular recognition by complementary guanine-cytosine base-pairing might be possible. It is thus prototypical of a new and potentially large class of ‘artificial oligonucleotides’.

Studies Directed Toward the Fabrication of a Synthetic Cation-conducting Channel Based on Lariat Eththe construction of biomolecules, many ‘feeble forces’ are involved as well. We have used feeble forces in model studies directed eventually to the synthesis of a self-assembling, cation-conducting channel. Specifically, we have prepared three models for portions of such a cation-conducting channel.
