All the chemicals were purchased from commercial sources and used without any further purification. 1H-NMR spectra were recorded with BRUKER AVANCE III 500 NMR instrument (CDCl3 solution) at 500 MHz. The single-crystal structure was tested on a D8 Venture SMART-CCD instrument with Mo-Kα radiation designed by Bruker from Germany. X-ray powder diffraction (XRD) measurements were performed with Cu-Kα radiation source (λ = 0.15406 nm) at 40 kV voltage and 25 mA current. IR spectra were performed on an IS50 FT-IR instrument. Thermogravimetric analysis was finished on a SDTQ600 thermogravimetric analysis instrument under N2 condition. The content of C, H and N was analysed by vario EL III elemental analysis instrument designed by Elementar Company from Germany.

Unless noted otherwise, all reagents were obtained from commercial sources and used without further purification. The 1-pyrenebutyric acid N-hydroxysuccinimide ester was obtained from Tokyo Chemical Industry Co., Ltd. (Tokyo, Japan). Dimethyl sulfoxide was obtained from Fujifilm Wako Pure Chemical Corporation (Osaka, Japan). DMSO-d6, was obtained from Sigma-Aldrich Inc. (St. Louis, MO, USA). UV absorption spectroscopy was performed using a DU-800 spectrophotometer (Beckman-Coulter, Brea, CA, USA). Fluorescence spectra were measured using a LS50B fluorescence spectrometer (Perkin Elmer, Waltham, MA, USA). Time-resolved fluorescence measurement was performed using a single photon counter FluoroCube (Horiba, Kyoto, Japan). 1H NMR spectra were recorded using an Avance III-500 NMR instrument (Bruker, Billerica, MA) at the Biomedical Research Institute, National Institute of Advanced Industrial Science and Technology (AIST). HRMS was performed by the Open Research Facilities Station, TIA Central Office, AIST.
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.
