In this work, the aromatic fluctuation index (FLU) that describes the fluctuation of electronic charge between adjacent atoms in a given ring is introduced as a new aromaticity measure. This new electronic criterion of aromaticity is based on the fact that aromaticity is related to the cyclic delocalized circulation of π electrons. It is defined not only considering the amount of electron sharing between contiguous atoms, which should be substantial in aromatic molecules, but also taking into account the similarity of electron sharing between adjacent atoms. For a series of rings in 15 planar polycyclic aromatic hydrocarbons, we have found that, in general, FLU is strongly correlated with other widely used indicators of local aromaticity, such as the harmonic-oscillator model of aromaticity, the nucleus independent chemical shift, and the para-delocalization index (PDI). In contrast to PDI, the FLU index can be applied to study the aromaticity of rings with any number of members and it can be used to analyze both the local and global aromatic character of rings and molecules.

Miquel SolaIn 1972 Erich Clar formulated his aromatic pi-sextet rule that allows discussing qualitatively the aromatic character of benzenoid species. Now, forty years later, Clar’s aromatic pi-sextet rule is still a source of inspiration for many chemists. This simple rule has been validated both experimentally and theoretically. In this review, we select some particular examples to highlight the achievement of Clar’s aromatic pi-sextet rule in many situations and we discuss two recent successful cases of its application.

Jordi PoaterMiquel SolaAromaticity cannot be measured directly by any physical or chemical experiment because it is not a well-defined magnitude. Its quantification is done indirectly from the measure of different properties that are usually found in aromatic compounds such as bond length equalisation, energetic stabilisation, and particular magnetic behaviour associated with induced ring currents. These properties have been used to set up the myriad of structural-, energetic-, and magnetic-based indices of aromaticity known to date. The cyclic delocalisation of mobile electrons in two or three dimensions is probably one of the key aspects that characterise aromatic compounds. However, it has not been until the last decade that electron delocalisation measures have been widely employed to quantify aromaticity. Some of these new indicators of aromaticity such as the PDI, FLU, ING, and INB were defined in our group. In this paper, we review the different existing descriptors of aromaticity that are based on electron delocalisation properties, we compare their performance with indices based on other properties, and we summarise a number of applications of electronic-based indices for the analysis of aromaticity in interesting chemical problems.

About Me
Miquel Solà (1964) obtained his PhD at the UAB in 1991, graduating with academic honors. His doctoral research under the supervision of Profs. Juan Bertran and Agustí Lledós was awarded with the Saint Albert Prize. In 1993, after several months in a private consultant company, he moved to the University of Girona (UdG) as an assistant researcher. In 1994, he conducted postdoctoral research in Amsterdam with Prof. Evert Jan Baerends and in 1995, in Calgary with Prof. Tom Ziegler. He was appointed assistant professor of the UdG in 1997. In 2001, he was awarded the Distinction for the Promotion of University Research (young scientist category). Since 2003, he holds a permanent position as a full professor in the UdG. He was awarded the ICREA Academia Prize three times, in 2009, 2014, and 2024. In 2013, he was awarded the Physical Chemistry prize by the Spanish Royal Society of Chemistry. In 2025, he received the medal of the Spanish Royal Society of Chemistry. He is coauthor on more than 500 scientific papers and has supervised 27 doctoral students. He serves on the Editorial Board of Theor. Chem. Acc. and Sci. Rep. journals. At the UdG, he previously served as director of the Institute of Computational Chemistry and Catalysis (2004-07), director of the Department of Chemistry (2007-10), and director of the School of Doctoral Studies( (2010-14 and 2018-22).
