X-ray crystallographic studies of ferrocene bis(nucleobase) conjugates reveal two-dimensional supramolecular organizations of backbones through self-assembled Watson-Crick and reverse Watson-Crick type pairs. Ferrocene-bis(thymine) conjugate self-assembles by reverse Watson-Crick pairing, while the corresponding bis(uracil) conjugate self-assembles by alternating WC and reverse WC type pairing. Such continuous assemblies are not seen in monosubstituted ferrocene nucleobase conjugates which form only planar sheets. The results are interesting from the point of understanding and engineering supramolecular assemblies through rational design of base pairing patterns.</p>1 aPatwa, Amit, N.1 aGupta, Susmita1 aGonnade, Rajesh, G.1 aKumar, Vaijayanti, A.1 aBhadbhade, Mohan, M.1 aGanesh, Krishna, N.  uhttps://library.ncl.res.in/content/ferrocene-linked-thymineuracil-conjugates-base-pairing-directed-self-assembly-and-001159nas a2200193   4500008004100000022001400041245012700055210006900182260007100251300001400322490000700336520037100343100002000714700002400734700002600758700002500784700002400809856013200833       2010                        eng d  a0022-326300aFerrocene-Bis(thymine/uracil) conjugates: base pairing directed, spacer dependent self-assembly and supramolecular packing0 aFerroceneBisthymineuracil conjugates base pairing directed space  a1155 16TH ST, NW, WASHINGTON, DC 20036 USAbAMER CHEMICAL SOCcDEC  a8705-87080 v753 a<p>X-ray crystallographic studies of methylene linked Ferrocene-bis(thymine/uracil) conjugates Fc(T:T)m and Fc(U:U)(M) reveal base dependent 2-D supramolecular assemblies generated via wobble self-pairing for bis-thymine and reverse wobble self-pairing for bis-uracil conjugates, differing in architecture from the corresponding butylene spacer linked conjugates</p>1 aPatwa, Amit, N.1 aGonnade, Rajesh, G.1 aKumar, Vaijayanti, A.1 aBhadbhade, Mohan, M.1 aGanesh, Krishna, N.  uhttps://library.ncl.res.in/content/ferrocene-bisthymineuracil-conjugates-base-pairing-directed-spacer-dependent-self-assembly-0
