All chemical reagents were purchased from FUJIFILM Wako Pure Chemical Corporation (Osaka, Japan) and Tokyo Chemical Industry Co., Ltd. (TCI, Tokyo, Japan). The starting polymerizable ionic liquid of [{CH2=C(CH3)COO(CH2)2}C3H3N2] (denoted as MAIm–N) was synthesized as a neutral compound, and [{CH2=C(CH3)COO(CH2)2}C3H3N2(C8H17)]Br (MAImC8·Br) were synthesized as bromide salts according to previous studies (Figure S1) [42 (link),43 (link),44 (link)].
Infrared (IR) spectra were recorded on a Jasco FT/IR-4200ST spectrometer (JASCO Corporation, Tokyo, Japan) by the KBr pellet method. Powder X-ray diffraction (XRD) patterns were measured with a Rigaku MiniFlex300 diffractometer (Rigaku Corporation, Tokyo, Japan) by using Cu Kα radiation (λ = 1.54056 Å) at ambient temperature. CHN (carbon, hydrogen, and nitrogen) elemental analyses were performed with a PerkinElmer 2400II elemental analyzer (PerkinElmer, Waltham, MA, USA).

Using a Fourier transform infrared spectrometer (iSTM 20 Thermo Fisher, Waltham, Massachusetts, USA) equipped with a Kinmen single attenuated total reflection accessory (ATR), the chemical structure of L, AL, and keratin hydrolysate PL coating material films was recorded in the range of 4000~600 cm−1 with a resolution of 16 cm−1. The elemental analysis of the L and AL was carried out using X-ray photoelectron spectroscopy (XPS) (madzu Corporation, Tokyo, Japan) and a PerkinElmer 2400II elemental analyzer (Perkin Elmer, Waltham, MA, USA). The thermal stabilities of the obtained films were determined using a thermogravimetric analyzer (TGA8000; PerkinElmer, Waltham, MA, USA) from room temperature (30 °C) to 500 °C in a nitrogen atmosphere at a rate of 10 °C min−1. The PL composites were characterized using a German Bruker D8 X-ray diffractometer (λ = 0.154 nm) in the range of 0–80° with a scanning rate of 10°/min.

The chemical shifts of the 1H, 13C{1H}, 11B{1H} and 19F{1H} NMR spectra determined in CDCl3 were given in ppm relative to tetramethylsilane (0.00 ppm for 1H and 13C{1H}) as an internal standard, or boron trifluoride diethyl-ether complex (0.00 ppm for 11B{1H}) and hexafluorobenzene (−164.9 ppm vs. CFCl3 for 19F{1H}) as external standards. High-resolution fast-atom bombardment mass spectroscopies (HR-FAB-MS) were carried out on a JEOL JMS-700N spectrometer. Elemental analyses (C, H, N) were performed by a Perkin Elmer 2400II elemental analyzer. UV-vis absorption spectra were recorded on a Jasco V-560 spectrophotometer. The corrected emission spectra were obtained by using a Jasco F-6500 spectrofluorometer (excitation wavelength = 365 nm). Fluorescence decay measurements were conducted by using a Hamamatsu Photonics picosecond fluorescence lifetime measurement system C11200 equipped with picosecond light pulser PLP-10 as a 405 nm excitation light source. Emission quantum yields were determined by using a Hamamatsu Photonic Absolute PL Quantum Yield Measurement System C9920-02 (excitation wavelength = 365 nm).

Each replicate consisted of one strip (27 square meters, approximately 112-115 plants). All fresh fruit were harvested from each strip and every fruit was weighed. Above 200 g per fruit was characterized as qualified fruit, otherwise it was defined as unqualified. Unqualified fruit was ultimately grouped by insect pest or disease. Total N from the harvest sweet corn leaves were determined by combustion (PerkinElmer 2400 II elemental analyzer, PerkinElmer, Shelton, CT, USA).

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.
