Polyaromatic compounds are well-known to intercalate DNA. Numerous anticancer chemotherapeutics have been developed upon the basis of this recognition motif. The compounds have been designed such that they interfere with the role of the topoisomerase

Chameleonic Binding of the Dimethyldiazaperopyrenium Dication by Cucurbit[8]uril

Autor: Amy A. Sarjeant, Ross S. Forgan, Ashish N. Basuray, J. Fraser Stoddart, Henri‐Pierre Jacquot de Rouville, Takashi Kikuchi, Chenfeng Ke, Karel J. Hartlieb, Josh W. Kurutz

Two are better than one: The diazaperopyrenium dication acts as both a viologen-like electron-poor and an electron-rich guest, resulting in the formation of a 1:2 complex with cucurbit[8]uril. This chameleonic binding facilitates deaggregation of the

Photoinduced Memory Effect in a Redox Controllable Bistable Mechanical Molecular Switch

Autor: Serena Silvi, Gokhan Barin, Alberto Credi, J. Fraser Stoddart, Hao Li, Ali Trabolsi, Sanjeev K. Dey, Ali Coskun, Ashish N. Basuray, Tommaso Avellini, Margherita Venturi

Publikováno v: Angewandte Chemie International Edition. 51:1611-1615

Herein, we discuss the performance of a molecular switch in the form of a bistable [2]rotaxane, which 1) undergoes relative mechanical movements of its ring and dumbbell components under redox control and thus can be switched between two states therm

Surface-Enhanced Raman Spectroelectrochemistry of TTF-Modified Self-Assembled Monolayers

Autor: Walter F. Paxton, Ashish N. Basuray, J. Fraser Stoddart, Samuel L. Kleinman, Richard P. Van Duyne

Publikováno v: The Journal of Physical Chemistry Letters. 2:1145-1149

Surface-enhanced Raman spectroscopy (SERS) was used to monitor the response of a self-assembled monolayer (SAM) of a tetrathiafulvalene (TTF) derivative on a gold film-over-nanosphere electrode. The electrochemical response observed was rationalized

The synthesis and the dynamic behavior of a bistable [2]rotaxane, based on a reverse donor–acceptor motif containing naphthalene diimide (NpI) and 4,4′-bipyridinium (BIPY2+) as two electron-deficient stations and bis-1,5-dioxynaphthalene[38]crown

Polycatenation under Thermodynamic Control

Autor: Ali Coskun, Ashish N. Basuray, Mark A. Olson, Lei Fang, J. Fraser Stoddart

Publikováno v: Angewandte Chemie. 122:3219-3224

Iodide-catalyzed reversible nucleophilic attacks have been exploited to access side-chain polycatenanes under thermodynamic control. Multiple catenations occurring all along the polymer chain are entirely driven to completion by the intra- and interm

Multiple homeostatic mechanisms in the control of P1 plasmid replication

Autor: Peter P. Papp, Richard A. Fekete, Ashish N. Basuray, Johan Paulsson, Majda Valjavec-Gratian, Dhruba K. Chattoraj, Nilangshu Das

Publikováno v: Proceedings of the National Academy of Sciences. 102:2856-2861

Many organisms control initiation of DNA replication by limiting supply or activity of initiator proteins. In plasmids, such as P1, initiators are limited primarily by transcription and dimerization. However, the relevance of initiator limitation to
