Steps to reproduce
Electronic absorption spectra were recorded using the Aquilon SF-104 (Russian Federation), the Agilent Cary 100 (USA), and the SOLAR SM2203 (Belarus). The fluorescence spectra have been taken using the Cary Eclipse (Varian-Agilent, USA-Australia; the detector voltage is 600 V), the Horiba Jobin Yvon Fluorolog 3, USA; the detector voltage is 950 V), and the SOLAR SM2203 (Belarus) spectrofluorometers. All experiments were performed in a thermostatic cell holder equipped with a Peltier PTC-2 heat transfer module at 298.2±0.1 K. Optical and fluorescence microscopy images were obtained using fluorescence microscopes using Micromed LUM-3 with a digital camera, ToupCam 5.0 MP CCD, and an Olympus BX-61 equipped with a QImaging MicroPublisher 3.3 digital camera. 1H-NMR spectra of the dyes were recorded on an Avance-500 (Bruker, Germany) spectrometer operating at 500 MHz. Elemental analysis was performed on a FLESH EA1112 (TermoQuest, Italy) elemental analyzer. MALDI-TOF analysis was performed on an AXIMA Confidence MALDI-TOF mass spectrometer (Shimadzu, Japan). Side UV illumination was applied using a UV lamp under a 254/365 nm exposure wavelength to obtain fluorescent images in the UV region. Quantum-chemical calculations have been done using Gaussian G09W, CHARMM. Molecular docking studies have been done using Autodock 4.2 (part of the MGLtools 1.5.7 package). Molecules have been visualized using PyMol 1.7, ChimeraX 1.4, Chimera 1.15, and Autodesk Fusion 360.
