The Functional Nanomaterials and Surfaces (FunNanoSurf) Group develops its activity on the fields of nanoscience and nanotechnology, with a focus on molecular electronics, molecular magnetism and biosensors. FunNanoSurf researchers design molecular systems that are useful for providing inputs at the micro-/nano- scales, operating on different surfaces and devices, paying special attention on the control and molecular organization.
The groups’ main areas of expertise include the synthesis of functional molecules/polymers & supramolecular aggregates, with special emphasis on those based on curcuminoids (curcumin derivatives), viologens and supramolecular hosts such as cyclodextrin and cucurbiturils, the characterization of these molecular-based materials and their immobilization on surfaces.
During 2019, FunNanoSurf has achieved a series of new molecular materials based on Curcuminoids (CCMoids) and porphyrins for different purposes. This way, (i) multifunctional CCMoids have been designed and attached to functionalized surfaces, functioning as sensors of boron, taking advantage of their effective anchoring groups and luminescent properties that switch upon coordination; (ii) a new family of PAH-CCMoids (polycyclic aromatic hydrocarbons) has been attained with the aims of anchoring such materials in hybrid graphene-based nanodevices forsingle-molecule electronic transport purposes; (iii) a number of CCMoids have been used as polytopic systems coordinating to transition metals and achieving high-dimensional systems, among them, 2D CCMoid-based materials that are been exfoliated and characterized on different substrates.
In addition, the versatile chemistry of CCMoids has allowed (iv) the creation of molecular units that can be covalently attached to functionalized electrodes, as for example, graphene and CNTs. The capacity of functionalized different parts of CCMoids (v) has allowed the development of supramolecular approaches to control the deposition of such bioinspired molecules on different substrates and microparticles and to obtain new bio(inspired) responsive supramolecular polymers. This is extended toward (vi) the creation of biommetic surfaces and theranostic materials. Regarding the porphyrins, the incorporation of chiral and achiral Zn-porphyrins to block copolymers via axial metal coordination for supramolecular hybrid materials has been developed.
