Sporer, C., Casal, L., Caballero, D., Samitier, J., Errachid, A., Perez-Garcia, L., (2009). Novel anionophores for biosensor applications: nano characterisation of SAMS based on amphiphilic imidazolium protophanes and cyclophanes on gold surfaces Sensor Letters 6th Maghreb-Europe Meeting on Materials and Their Applications for Devices and Physical, Chemical and Biological Sensors , AMER SCIENTIFIC PUBLISHERS (Rabat, Morocco) 7, (5), 757-764

Here we report on the results of surface deposition of the novel amphiphilic imidazolium heterocyclophanes and protophanes 1, 2, 3 onto gold electrodes by soft lithography and wet chemistry techniques. Depending on the specific functionalization conditions chosen, the surface properties and the pattern composition can vary widely. The formation of aggregates of monolayers or oligolayer structures and of rings with nano dimensioned wall widths has been investigated with Atomic Force Microscopy (AFM), Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) and Contact angle measurements.
