An amide cyclophane
The title compound, 8,18-dithia-2,6-diaza-13(1,4)-piperidina-1(1,2),4(1,3),7(1,2)-tribenzenaoctadecaphane-10,15-diyne-3,6-dione, C32H30N4O2S2, is composed of a relatively planar bis-(2-mercaptophen-yl)isophthalamide unit linked to a bridging 1,4-di(but-2-yn-1-yl)piperazine unit, forming a macrocycle. The isophthalamide ring is inclined to the outer mercaptophenyl rings by 8.18 (11) and 5.59 (10...
متن کاملPressure catalyzed bond dissociation in an anthracene cyclophane photodimer.
The anthracene cyclophane bis-anthracene (BA) can undergo a [4 + 4] photocycloaddition reaction that results in a photodimer with two cyclobutane rings. We find that the subsequent dissociation of the dimer, which involves the rupture of two carbon-carbon bonds, is strongly accelerated by the application of mild pressures. The reaction kinetics of the dimer dissociation in a Zeonex (polycyclool...
متن کاملSelf-assembled cage as an endo-template for cyclophane synthesis.
An organic-pillared coordination cage templated the quantitative formation of siloxane-bridged cyclophanes within its cavity via hydrolysis and condensation of 1,6- and 1,8-bis(trimethoxysilyl)pyrene.
متن کاملTriply ferrocene-bridged boroxine cyclophane.
Mild solvothermal dehydration of 1,1'-ferrocenediboronic acid produces a triply ferrocene-bridged boroxine cyclophane. Its crystal structure reveals a rigid trigonal prism that presents a minimal boroxine-based covalent organic polyhedron (COP).
متن کاملDesigning cyclophane-based molecular wire sensors.
We propose a model molecular wire sensor that can detect zerovalent chromium by a strong increase in conductance when included in a metal-molecule-metal junction. An essential part of the sensor is a paracyclophane unit that binds to the metal atom. The nature and the energies of the molecular orbitals change drastically after the complex is formed, resulting in a 10- to 12-fold increase in con...
