The NMR spectra were recorded
at room temperature on Avance II 400, Avance III 400, Avance I 500,
or Avance III 600 spectrometers (Bruker). DOSY NMR spectra were recorded
on a Bruker Avance I 500 using a bipolar pulse program (stebpgp1s)
with d20 = 0.2 and p30 = 2750 μs for gradient amplitudes from
5 to 95%. Spectra were calibrated using the solvent signals, and the
data were analyzed using MestReNova 14.1.2 (Mestrelab Research S.L.).

NMR analyses were performed as follows: For ¹H spectra, an Avance I 500 (UltraShield 500 MHz, SEI 500 S2 probe head (5 mm, inverse with Z-gradient), Autosampler B-ACS 60) from Bruker Instruments (Karlsruhe, Germany) was used. The software installed was TopSpin 2.1 (Bruker Instruments, Karlsruhe, Germany). For ¹³C spectra, either an Avance I 500 (Cryomagnet BZH 500 MHz, Autosampler B-ACS 60) or an Advance III 500 system with an UltraShield PLUS 500 MHz magnet and a cryo probe head (5 mm CPQNP, ¹H/¹³C/³¹P/¹⁹F/²⁹Si (Z-gradient), Autosampler B-ACS 120) both from Bruker Instruments (Karlsruhe, Germany) were used. The software installed was TopSpin 3.0, respectively (Bruker Instruments, Karlsruhe, Germany). The measurements were performed at magnetic fields of 11.75 Tesla. The resonance frequencies of ¹H and ¹³C were 500.13 MHz and 125.77 MHz, respectively, and the temperature was 300 K. Data analysis was performed with the MestReNova Software (Mestrelab Research, Santiago de Compostela, Spain), TOPSPIN or XWIN NMR. The one-dimensional ¹H and ¹³C NMR spectra, and the two-dimensional COSY (magnitude mode or phase-sensitive), HSQC, HSQC-DEPTedited, HSQC-TOCSY, NOESY (with 1 s mixing), TOCSY (with 60 ms mixing) and HMBC spectra were measured with standard Bruker parameter sets.

All solvents (Aldrich, Acros) and reagents MeO-PEG₄-OMs (Aldrich) and MeO-PEG₁₂-OMs (Creative Peg Works), CuTC (Aldrich) were reagent grade, or better, and were used as received. meso-Tetrakis(p-methoxyphenyl)-2,3-dihydroxychlorin (7),^{28 (link)} and BODIPYs 10 and 11 were prepared as described previously.^{27 (link)}Analytical (aluminum backed, silica gel 60, 250 μm thickness) and preparative (20 × 20 cm, glass backed, silica gel 60, 500 μm thickness) TLC plates, and the flash column silica gel (standard grade, 60 Å, 32–63 μm) used were provided by Sorbent Technologies, Atlanta, GA.
¹H and ¹³C NMR spectra were recorded on Bruker Avance II 400 and Bruker Avance I 500 instruments in the solvents indicated, and were referenced to residual solvent peaks. High and low resolution ESI mass spectra were provided by the Mass Spectrometry Facilities at the Department of Chemistry, University of Connecticut. MALDI MS Spectra were provided by the Mass Spectrometry & Proteomics Facility at the University of Notre Dame. UV-vis and fluorescence spectra were recorded on Cary 50 and Cary Eclipse photospectrometers, Varian Inc, respectively, and IR spectra on a Bruker Alpha-P FT-IR spectrometer using a diamond ATR unit.

The transmission electron microscopy (TEM) characterizations were performed using a JEOL 1011 microscope operating at 100 kV. A drop of gold nanowire suspension in hexane was deposited on a carbon-coated copper grid and dried under vacuum.
Small Angle X-ray Diffraction was performed on a PANalytical Empyrean diffractometer equipped with a Cobalt source, λ (Co Kα1/Kα2) = 1.7889/1.792Å, a Bragg-Brentano HD optics with a divergence slit of 1/32° and an anti-scatter slit of 1/8°, and a PIXcel1D-Medpix3 detector. Several drops of gold nanowire suspension in hexane were deposited on a zero-background silicon substrate and then dried at room temperature for 3 min.
Solution NMR spectra were obtained on a Bruker Avance I 500 spectrometer equipped with a 5 mm triple resonance inverse Z-gradient probe (TBI 1 H, 31 P, BB). 1 H NMR spectrum were recorded in toluene-d8 at 293 K. Diffusion measurements were made using the stimulated echo pulse sequence. The mixing time of NOESY experiment were set to 100 ms. Chemical shifts (δ, parts per million) are quoted relative to SiMe4 ( 1 H). They were measured by internal referencing to the residual 1 H resonances of the deuterated solvent (toluene-d8, 1 H δ 2.09 as a quintuplet of the methyl group). 31 P chemical shifts were referenced to an external 85% H3PO4 sample.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
