Curved nanographenes: Multiple emission, thermally activated delayed fluorescence, and non-radiative decay

The intriguing and rich photophysical properties of three curved nanographenes (CNG 6, 7, and 8) are investigated by time-resolved and temperature-dependent photoluminescence (PL) spectroscopy. CNG 7 and 8 exhibit dual fluorescence, as well as dual phosphorescence at low temperature in the main PL bands. In addition, hot bands are detected in fluorescence as well as phosphorescence, and, in the narrow temperature range of 100–140 K, thermally activated delayed fluorescence (TADF) with lifetimes on the millisecond time-scale is observed. These findings are rationalized by quantum-chemical simulations, which predict a single minimum of the S1 potential of CNG 6, but two S1 minima for CNG 7 and CNG 8, with considerable geometric reorganization between them, in agreement with the experimental findings. Additionally, a higher-lying S2 minimum close to S1 is optimized for the three CNG, from where emission is also possible due to thermal activation and, hence, non-Kasha behavior. The presence of higher-lying dark triplet states close to the S1 minima provides mechanistic evidence for the TADF phenomena observed. Non-radiative decay of the T1 state appears to be thermally activated with activation energies of roughly 100 meV and leads to disappearance of phosphorescence and TADF at T > 140

Evaluación del impacto del perfil del alumnado y su formación preuniversitaria en la asignatura de Química del primer curso de grado en tres facultades de ciencias de la UCM

En este trabajo se analizan y comparan las características del perfil de los estudiantes de nuevo acceso en las titulaciones de Química, Biología y Óptica-Optometría, en tres facultades de Ciencias de la Universidad Complutense de Madrid (UCM). Se examina el rendimiento aca-démico del alumnado en la materia básica de Química, así como su relación con la situación de partida o perfil del alumnado que ingresa en la Universidad. Asimismo, se han detectado las carencias que presentan los estudiantes de primer curso de Grado en dicha materia, a partir de la autoevaluación del grado de conocimiento del temario preuniversitario de la asignatura de Química. Los resultados señalan que el alumnado mayoritariamente ha cursado la asignatura de Química, destacando que habría elegido otro Grado si hubiese obtenido la nota de acceso necesaria. Además, los estudiantes manifiestan menor conocimiento en temas que, en general, se imparten específicamente en el segundo curso de Bachillerato.The impact of the pre-university profile of first-year students of Chemistry, Biology and Optics-Optometry degrees in three Faculties of the Complutense University of Madrid (UCM) is discussed in this paper. This work also analyses the academic performance of the students in a basic subject such as Chemistry, as well as its relationship with the starting situation or profile of the first-year students. Likewise, the major shortcomings detected by the first-year students in the basic subject of Chemistry in the three degrees have been discussed, based on the self-evaluation by the students of their degree of knowledge of the pre-university subject of Chemistry. The results show that the majority of the students took Chemistry training in the Baccalaureate, and most of them would have chosen a different university degree provided they had obtained the necessary qualifications for it. In addition, students show less knowledge in subjects that, in general, are taught specifically in the second year of Baccalaureate

Evaluación del impacto del perfil del alumnado en la valoración de la actividad docente del profesorado

En este proyecto se analiza el perfil de los estudiantes de primer curso en tres Grados (Química, Biología y Óptica-Optometría) de las Facultades de Ciencias de la UCM, detectando las carencias que presentan los estudiantes en una materia básica como la Química. Se comparan los resultados con los obtenidos en el curso académico 2016-2017. Asimismo se analiza la relación del perfil del alumnado con la valoración de la actividad docente del profesorado que realizan los estudiantes dentro del programa DOCENTIA

Exploring BODIPY Derivatives as Singlet Oxygen Photosensitizers for PDT

This minireview is devoted to honoring the memory of Dr. Thomas Dougherty, a pioneer of modern photodynamic therapy (PDT). It compiles the most important inputs made by our research group since 2012 in the development of new photosensitizers based on BODIPY chromophore which, thanks to the rich BODIPY chemistry, allows a finely tuned design of the photophysical properties of this family of dyes to serve as efficient photosensitizers for the generation of singlet oxygen. These two factors, photophysical tuning and workable chemistry, have turned BODIPY chromophore as one of the most promising dyes for the development of improved photosensitizers for PDT. In this line, this minireview is mainly related to the establishment of chemical methods and structural designs for enabling efficient singlet oxygen generation in BODIPYs. The approaches include the incorporation of heavy atoms, such as halogens (iodine or bromine) in different number and positions on the BODIPY scaffold, and also transition metal atoms, by their complexation with Ir(III) center, for instance. On the other hand, low‐toxicity approaches, without involving heavy metals, have been developed by preparing several orthogonal BODIPY dimers with different substitution patterns. The advantages and drawbacks of all these diverse molecular designs based on BODIPY structural framework are described
