Group for Applied Ultrafast Spectroscopy and Photochemical Identification

In collaboration with the scientists from Institute Ruđer Bošković we published a paper about photogeneration of carbenes in anti-Kasha reactions from upper excited states of diazoalkanes.

Mateo Forjan defended his PhD thesis “Ultrafast Spectroscopy and Photochemistry of Intermediates With Potential Application in Biology and Medicine”.

M. Forjan and S. Vdović, in collaboration with the scientists from Institute Ruđer Bošković and Politecnico di Milano have published a paper about photodehydration mechanisms of quinone methide from 2-naphthol derivatives.

Recently we moved to our new laboratory within the Centre for Advanced Laser Techniques (CALT).

M. Forjan and S. Vdović, in collaboration with the scientists from Institute Ruđer Bošković,  Politecnico di Milano and University of Bern have published a paper about photogeneration of quinone methide from adamantylphenol in an ultrafast non-adiabatic dehydration reaction.

Vedran Brusar defended his diploma thesis “Transient absorption of Rhodamine B” where he used visible NOPA pulses for excitation and resulting transients for assessment of NOPA pulse duration.

Mateo Forjan participated in Central European Conference on Photochemistry 2020 held in Bad Hofgastein, Austria with the poster titled ”Ultrafast Transient Absorption of Phenolic and Adamantyl Compounds.

M. Forjan participated in Laserlab Europe user meeting in Coimbra, Portugal with oral talk titled ”Ultrafast Transient Absorption of Phenolic and Adamantyl Compounds”.

Mateo Forjan participated in the Ultrafast Optics XII Conference held in Bol, Croatia with the poster titled ”Ultrafast Transient Absorption of Adamantyl Phenol”.

Having the opportunity to apply for experimental time at one of the Laserlab-Europe centres, we prepared a project “Ultrafast transient absorption of adamantyl-phenol and the formation of quinone methide”

Transient absorption of DCM dye (4-(Dicyanomethylene)–2-methyl-6-(4-dimethylaminostyryl)–4H-pyran) dissolved in ethanol was measured on a time scale of 15 picoseconds with the time step of 100 femtoseconds.

Transient absorption of phenol derivatives dissolved in 50:50 mixture of acetonitrile (C₂H₃N) and water was measured. Concentration of the solution was 5 x 10^-4 M while the absorbance at the pump wavelength (267nm) was 0.72 per cm.

Mateo Forjan attended a Croatian Physical Society conference held in Beli Manastir, Croatia in October of 2018. He contributed the conference with a poster and a short speech followed by discussions during poster sessions.

Optical kerr effect (kerr gating) was studied in benzene and a 50:50 mixture of water and acetonitrile. With the analysis of data, time resolution of the experiment is defined and reorientational times of the mentioned molecules are qualitatively compared. 

Mateo Forjan defended his diploma thesis “Ultrafast Transient Absorption of Photochemical Reactions” and thus graduated at University of Zagreb, Faculty of Science, Physics Department. Diploma thesis focused on the transient absorption of dye molecule rhodamine B
