摘要：(Figure Presented) A molecular abacus: In a [2]rotaxane that mimicks a half adder with distinct AND and XOR logic gates, all the inputs (I) and outputs (O) are photochemical (see scheme; F = fluorescence, A = absorbance). Reversible E&rarrZ photoisomerization about two double bonds (shown in red and dark blue) in the thread molecule leads to four conformers that have different spectral properties. ? 2005 Wiley-VCH Verlag GmbH & Co.
