Molecular assembly and disassembly: novel photolabile molecular hosts
1Department of Chemistry and Biochemistry, University of Denver, Denver, Colorado 80208-2436, USA.
Abstract:
A new approach to the assembly and photochemical disassembly of molecular hosts is developed. It is based on photoinduced fragmentation in hydroxyalkyl dithianes and utilizes a novel spiro-bis-dithiane as a photolabile molecular tether to link two formylated macromolecular blocks, e.g., formyl calixarenes or formyl dibenzocrown ethers. A key feature of this molecular system is that after an assembly-disassembly cycle the starting macromolecular blocks are recovered intact and can be used again.
