Embodiment
[0025] In a first aspect, the present disclosure provides a composition comprising a compound selected from Structure 1:
[0026]
[0027] where R 1 to R 24 each independently selected from hydrogen, hydrocarbyl, substituted hydrocarbyl, cyano, alkoxy, aryloxy, or NR' 2 , wherein R' is selected from aryl or heteroaryl; and
[0028] where optionally, R 1 to R 24 Two or more of form one or more ring structures; and
[0029] wherein Z is selected from the group (1) or (2):
[0030] (1) (2) and
[0031] Where optionally, one or more hydrogens may be replaced with deuterium.
[0032] Compounds of structure 1 may comprise a combination of two or more embodiments as described herein.
[0033] Compositions of the invention may comprise a combination of two or more of the embodiments described herein.
[0034] As used herein, R1=R 1 , R2=R 2 , R3=R 3 Wait. As used herein, NR'2=NR' 2 .
[0035] In one embodiment, for Structure 1, R1 to R24 are each independently se...

[0181] Reagents and Test Methods
[0182] All solvents and reagents were obtained from commercial vendors, including Sigma-Aldrich, TCI, and Alfa Aesar, and were prepared in the highest available purity and / or when necessary. When used in the form of recrystallization before use. Dry solvents were obtained from an in-house purification / distribution system (hexane, toluene, and tetrahydrofuran) or purchased from Sigma-Aldrich. All experiments involving "water-sensitive compounds" were performed in "dry-dried" glassware under a nitrogen atmosphere or in a glove box. Reactions were monitored by analytical thin layer chromatography (TLC) on pre-coated glass plates (VWR 60 F254) and visualized by UV light and / or potassium permanganate staining. Flash chromatography was performed on an ISCO COMBIFLASH system with a GRACERESOLV column. GC-mass spectroscopy (GC-MS) was performed on an HP 6890 series GC system with a "12m x 0.2mm x 0.55μΜ" DB-MS column (coiled).
