Two new pyrene-polychlorotriphenylmethyl (PTM) dyads and triads have been synthesized and characterized by optical, magnetic and electrochemical methods. The interplay between the different electronic states of the PTM moiety in the dyads and triads and the optical and magnetic properties of the molecules have been studied. The electronic spectra of the radicals show the intramolecular charge-transfer (ICT) transition at around 700 nm due to the acceptor character of the PTM radical. In the diamagnetic protonated derivatives, the fluorescence due to the pyrene is maintained, whereas in the radicals and the corresponding anions there is a clear quenching of the fluorescence. The redox activity of PTM radicals that are easily reduced to the corresponding carbanion has been exploited to fabricate electrochemical switches with optical and magnetic response.

It is shown that the paramagnetism of the polychlorotriphenylmethyl (PTM) radical molecule in the form of a Kondo anomaly is preserved in two- and three-terminal solid-state devices, regardless of mechanical and electrostatic changes. Indeed, reported evidences demonstrate that the Kondo anomaly is robust under electrodes displacement and changes of the electrostatic environment pointing to a localized orbital in the radical as the source of magnetism. Strong support to this picture is provided by DFT calculations and measurements of the corresponding non-radical species. These results pave the way towards the use of all-organic neutral radical molecules in spintronics devices and open the door to further investigations into Kondo physics.
In nature, cells react to complex mechanical and biological stimuli whose understanding is essential for tissue construction in regenerative medicine. A review how research progresses toward the design of integrative, holistic scaffold platforms based on the exploration of individual mechanical and biological effectors and their further combination has been published in Nanomedicinejournal.

Participation of the NANOMOL group in the Mobile World Centre 2015 exhibition of devices fabricated in the framework of collaboration with the Ramón Llull University - La Salle Campus Barcelona
The curious Link device was presented in the section Music in the air. This device allows composing music with the coloured harp by bringing one's hands close to its surfaces. This instrument integrates nanosensors developed by the NANOMOL group which detect variations in temperatures. The sensor placed inside the musical instrument sense the temperature differences between the ambient and the hand and activates the different sounds. This sensor is constructed as a versatile film which allows it to be installed easily in different materials.
