Deviation from Beer's law and relationship of aggregation with the effective TPA coefficient: UV-vis studies on a series of low symmetry monophthalocyanines bearing a cyclotriphosphazene substituent

Autor: Alexander Yu. Tolbin, Vladimir I. Shestov, Mikhail S. Savelyev, Alexander Yu. Gerasimenko

Publikováno v: New Journal of Chemistry. 47:1165-1173

A new “Extinction model” was developed to calculate aggregation threshold. The possibility of creating a forecasting model is shown on the example of establishing a correlation between aggregation and NLO properties.

A New Way to Predict the Efficiency of Optical Limiters without Providing an Experiment: Processing of TDDFT Calculations for the Case of Pure Two-Photon Absorption

Autor: Alexander Yu. Tolbin, Mikhail S. Savelyev, Alexander Yu. Gerasimenko, Victor E. Pushkarev

Publikováno v: ACS Omega. 7:28658-28666

Laser-power-limiting devices play a predominant role in photonics because of their potential for protecting human eyes and optical devices that are sensitive to intense laser beams. This paper describes a new methodology for predicting the efficiency

Conjugates of thermally stable phthalocyanine J-type dimers with single-walled carbon nanotubes for enhanced optical limiting applications

Autor: Mikhail S. Savelyev, Alexander Yu. Gerasimenko, Alexander Yu. Tolbin, Sergey V. Selishchev, Vitaly M. Podgaetskii, Sergey A. Tereshchenko

Publikováno v: Optics & Laser Technology. 117:272-279

The widespread application of laser devices requires development of new protections against light pulses of high intensity. This problem is relevant because of the danger of hitting the civil aviation pilots with bright and powerful radiation origina
