Quantum yield spectrometer c11347 quantaurus

High-performance liquid chromatography (HPLC) was measured on a Waters 2487 (600E) equipment with a column of Poroshell 120 (EC-C18, 2.7 μm, 4.6 × 150 mm), using acetonitrile/water mixture (ratio = 9:1, v/v) with a flow rate of 1.0 mL/min. Nuclear magnetic resonance (NMR) spectra were carried out on a Bruker AVIII 400 MHz NMR spectrometer equipped with a Dual Probe, using deuterated chloroform (CDCl₃) as the solvent. High-resolution mass spectra (HRMS) were measured on a GCT premier CAB048 mass spectrometer manipulated in a GC-TOF module with chemical ionization (CI). Ultraviolet-visible (UV-Vis) spectra were collected on a Varian Cary 50 Conc UV-Visible Spectrophotometer with Peltier. Photoluminescence (PL) spectra and their lifetimes at room temperature and 77 K were recorded on an Edinburgh FLS980 Spectrometer. Absolute quantum yield (QY) was collected on a Hamamatsu Quantum Yield Spectrometer C11347 Quantaurus. Single-crystal X-ray diffraction (XRD) was carried out on a Rigaku Oxford Diffraction (SuperNova) with Atlas diffractometer (Cu Kα (λ = 1.54184 Å)). The single-crystal structures were solved with Olex2 software. Dynamic light scattering (DLS) measurements for the diameter of aggregates were measured on a Malvern Zetasizer Nano ZS equipment at room temperature. All digital photos of crystals and amorphous compounds were recorded on a Canon EOS 60D camera.

NMR measurements of ¹H and ¹³C were conducted on a Bruker AVIII 400 MHz NMR spectrometer equipped with a Dual Probe. High-resolution mass spectra (HRMS) were performed on a CT Premier CAB048 mass spectrometer using a positive ESI-TOF module. Ultraviolet-visible (UV-Vis) spectra were recorded on a Varian Cary 50 UV-Visible Spectrophotometer. Photoluminescence (PL) spectra were carried out on Fluorolog®-3 (HORIBA) spectrofluorometer. Absolute quantum yields (QY) were collected using an integrating sphere on a Hamamatsu Quantum Yield Spectrometer C11347 Quantaurus. Fluorescence lifetime was recorded on an Edinburgh FLS980 Spectrometer. Dynamic light scattering (DLS) of the diameters of aggregates was measured on Malvern Zetasizer Nano ZS equipment at room temperature. Single-crystal structures of four compounds were confirmed through single-crystal X-ray diffraction on a Rigaku Oxford Diffraction (SuperNova) with Atlas diffractometer (Cu Kα (λ = 1.54184 Å) and solved using Olex2 software. All digital photographs of the solution, mixture, and crystalline powder were recorded using a Canon EOS 60D camera.
