Related Products of 4221-99-2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: (S)-Butan-2-ol, is researched, Molecular C4H10O, CAS is 4221-99-2, about Stability Tuning of Vapor-Adsorbed State of Vapochromic Pt(II) Complex by Introduction of Chiral Moiety.

New luminescent Pt(II) complexes with chiral ester chains, [PtCl2(R,R-bpybe)] (R-1; bpybe = 2,2′-bipyridine-4,4′-dicarboxylic acid di-Bu ester) and its racemic mixture (rac-1) with the chiral isomer, S-1, were synthesized, and their vapochromic behavior was investigated. Single-crystal x-ray structural anal. revealed that the rac-1 crystal was composed of only one crystallog. independent column formed by alternating stacking of R-1 and S-1 by the effective intermol. Pt···Pt interaction. In contrast, three types of columnar structures with different Pt···Pt interactions were found for the R-1 crystal, probably because of the different packing of the chiral ester chains between the columns. Consequently, the estimated mol. volume of R-1 was slightly larger than that in the racemic crystal rac-1, although they have the same chem. formula. The x-ray structure of the toluene-adsorbed rac-1 (rac-1·toluene) also indicated that the intermol. Pt···Pt interaction, which was effective for unsolvated rac-1, was completely canceled out by adsorption of toluene vapor. Both the rac-1 and R-1 crystals exhibited similar vapochromism driven by toluene vapor adsorption/desorption that switched the emission origin between the strongly emissive 3MMLCT (metal-metal-to-ligand charge transfer) to the weakly emissive 3π-π* phosphorescence. Although both crystals had the same chem. formula, the toluene vapor desorption temperature of R-1·toluene (84°) was obviously lower than that of rac-1·toluene (107°), suggesting that the binding interaction with toluene mols. was weaker in R-1·toluene than in rac-1·toluene.
