Title of the project: Development of new optically active boron cluster-based fluorophores as good candidates for two-photon absorption spectroscopy

Supervisor and Host institution: Dr. Rosario Núñez at the Institute of Materials Science of Barcelona (ICMAB-CSIC)

The two photon absorption (TPA) process is a third-order nonlinear optical (NLO) process in which materials simultaneously absorb two photons. Materials that exhibit large two-photon cross section can be applied like 3D optical data storage, optical limiting, microfabrication, photodynamic therapy or imaging. Despite of unique structural and electronic properties of boron clusters, some boron based p-cojugated systems have been reported. The main aim of the project is the preparation and characterization of novel boron cluster derivatives linked to highly conjugated systems to construct a new generation of optical active systems. The advantage of incorporating boron clusters would be improved hydrophobicity, low toxicity, thermal and chemical stability, among others. Further, these compounds might be regarded as potential candidates for anticancer agents for boron neutron capture therapy (BNCT).

"DOC-FAM and MSCA is an opportunity to think about our roles as citizens & researchers. It's an experience to delve deep into the World of Science"

My first major introduction with research came in 2016, when I worked on my master dissertation titled as “Application of Organoruthenium in Photodynamic Therapy” at the department of chemistry of Vellore Institute of Technology (VIT), India. During this time, my experience in research gave me an opportunity to publish and present my work in various scientific platforms. Fortunately, I came across DOC FAM and MSCA programme and the kind of work our research group Inorganic Materials and Catalysis laboratory does. The programme and the institute offers an excellent ambience which can challenge me intellectually, provide a good work culture but also enhance my extracurricular skills like in communication and to face social challenges in today’s world.      

So far my experience has given me confidence in the planning and execution of a range of experiments as well as addressing common problems faced. With all these strong positives I strive for an active participation in cutting-edge science and want to pursue my scientific ambitions to maximize my potential as a researcher.
