Scientific Interests

MAIN SCIENTIFIC ACHIEVEMENTS

• Created a field of materials akin to zeolites: microporous silicates of transition metals and lanthanides (over 100 novel Ti, Zr, V, Nb, Cu, Sn, Ca, Y, Ce and other Ln silicates, so-called AV and AM materials) processed in the form of powders, membranes and films. To be clear, these are stoichiometric materials, not metal-doped zeolites, whose archetypal solid is titanium silicate ETS-10 (Nature367: 347, 1994). He has explored applications in luminescence (J. Am. Chem. Soc., 137: 3051, 2015), catalysis, gas sorption and separation, ion exchange, magnetism and as MRI contrast agentes (J. Phys. Chem. B, 1997, 10: 7114, 1997, Eur. J. Inorg. Chem., 801, 2000J. Am. Chem. Soc., 125: 14573, 2003Angew. Chem. Int. Ed., 45: 7938, 2006J. Am. Chem. Soc., 131: 8620, 2009J. Am. Chem. Soc., 137: 3051, 2015). Outstandingly, one zirconium silicate has found a real commercial application as a drug for the treatment of hyperkalemia.

• Developed unprecedented luminescent lanthanide-bearing Metal Organic Frameworks (MOFs) and coordination polymers (Angew. Chem. Int. Ed., 47: 1080, 2008) and, in particular, pioneered the field of MOFs nanothermometry (ACS Nano7: 7213, 2013Adv. Funct. Mater., 25: 2824, 2015Chem. Eur. J., 22: 14782, 2016). Representative other contributions include MOFs transposition of chirality (Inorg. Chem., 51: 1703, 2012), Chem. Commun., 49: 11668, 2013), 2D-3D interconvertible MOFs, and photocatalytic MOFs – Cr(III) and Ag nanoparticles composites (Chem. Eur. J., 21: 11072, 2015).

• Became interested in MOFs and COFs for Li ion batteries expanded due to a competitive FCT project grant and the ERC Starting grant to my co-worker M. Souto. We are focusing on electroactive organic ligands for electronic applications, including perylene materials (Inorg. Chem., 62: 7834, 2023) and multivariate radical MOFs (Chem. Mater, 10.1021/acs.chemmater.3c02460), with notable success in COFs synthesis too (Angew. Chem.Int. Ed., 62: e202302872(1 of 9), 2023).

• Designed a photoresponsive crystalline organic-inorganic hybrid ferroelectric material with a high Curie temperature (423 K), paving the way for accomplishing multiple-state ferroelectric memories, optical switches, and various optoelectronic devices (J. Am. Chem. Soc.,142: 16990, 2020, J. Am. Chem. Soc., 2023, doi.org/10.1021/jacs.3c01530).

 Developed oxide nanoparticles for imaging contrast agents (ACS Nano, 4: 5339, 2010), bimodal imaging (Biomater., 33: 925, 2012), and thermometry (Nature Nanotech11: 851, 2016Adv. Mater., 35: 4868, 2013).

 Designed materials for small-drugs release (including NO, J. Am. Chem. Soc., 133: 6396, 2011).

• Devised materials for a more sustainable World (including anti-mosquito nets, ACS Appl. Mater. Interfaces9: 22112, 2017; and uranyl capture Angew. Chem., Intl. Ed., 58: 1, 2019).

• Designed (ca. 40) heterogeneous catalysts based on mesoporous silicas derivatized with metal complexes (J. Mater. Chem., 12: 1735, 2002), and ordered benzene-silica hybrids with molecular-scale periodicity in the walls and different mesopore sizes (J. Mater. Chem., 13:1910, 2003).

• Elucidated the structure of minerals using NMR and XRD techniques (J. Am. Chem. Soc., 113: 7100, 1991J. Am. Chem. Soc., 114: 6867, 1992Am. Mineral., 103: 812, 2018).

• Investigated the mechanisms of adsorption and activation of CO2 on nanoporous materials (Chem. Mater., 23: 1387, 2011).

• Pioneered the development and application of solid-state NMR techniques for studying (i) quadrupolar (I>1/2) nuclei, encompassing 2H exchange NMR (J. Am. Chem. Soc., 114: 6867, 1992), quadrupole nutation and DOR (Solid State NMR1: 217, 1992), multiple-quantum MAS NMR and related techniques (FAM MQ MAS, HETCOR MQ MAS, ST MAS, I-ST MAS...) (J. Phys. Chem., 100: 17889, 1996Solid State NMR, 21: 61, 2002Magn. Reson. Chem., 41: 679, 2003), and (ii) 1H high-resolution CRAMPS techniques (FSLG, PMLG, DUMBO) (J. Mag. Reson., 199: 111, 2009Chem. Phys. Lett., 470: 337, 2009). Recent interests include NMR crystallography (Cryst. Grow Design, 13: 2390, 2013) and the development of molecules, such as trimethylphosphine oxide, to study by NMR zeolite's acidity (J. Am. Chem. Soc., 143: 13616, 2021).

SOCIETAL IMPACT

Rocha is perhaps best known for having extended the realm of zeolitic materials to transition metal and Ln silicate solids. Notably, one of my creations, AV-13 (Inorg. Chim. Acta, 356: 19, 2003), was later modified and evaluated by ZS Pharma, now a part of AstraZeneca, for treating hyperkalemia (excess potassium in the bloodstream). This innovation led to the development of Lokelma, an orally administered drug that has received approval from both the FDA and the EMA and is now available in markets and institutions across Europe (including hospitals in Portugal), the US, China, and Japan. I served as a project lead and consultant for these companies from 2016 to 2018, thereby making a significant impact in the pharmaceutical industry and enhancing patient care globally.
