A Novel and Perfectly Aligned Crystal of a Ferrocenyl Chromophore Displaying High Quadratic Nonlinear Optical Bulk Efficiency

Abstract

The highest nonlinear optical bulk efficiency for a 2‐(4‐nitrophenyl)ethenylferrocene (140 times that of urea) has been achieved for E‐4 owing to a favourable noncentrosymmetrical packing in which all molecules are perfectly aligned (P1 space group).

Ferrocenyl and pyridyl methylenepyrans as potential precursors of organometallic electron-rich extended bipyrans: Synthesis, characterization and crystal structure

“…Similarly, the ferrocenylmethylenepyran 3 ( Fig. 2) was obtained from the mono-protected ferrocene-1,1 0 -dicarboxaldehyde [16] (39% yield). Subsequent acid hydrolysis of the acetal function led to the ferrocenylpyran aldehyde 4 in 57% yield (Fig.…”

“…[15] and mono-protected ferrocene-1,1 0 -dicarboxaldehyde was synthesized as described previously by Balavoine and coll. [16]. Ferrocenyl acetylene and the corresponding aldehyde D were prepared according to Ref.…”

Synthesis and catalytic applications of new chiral ferrocenyl P,O ligands

“…The synthesis of cyclic acetals was successfully carried out for the 1,2 diols as well as for 1,3 diols (see Table 1) in toluene in presence of a catalytic amount of the organic acid, camphorsulfonic acid (CSA) with continuous removal of water by distillation [17]. In the case of compound (8a), the new acetalic carbon (carbon 1 of the 1,3-dioxolane ring) is asymmetric.…”

Ferrocenyl Phosphorhydrazone Dendrimers Synthesis, and Electrochemical and Catalytic Properties

“…The functionalization of ferrocene was carried out thanks to several efficient syntheses [19][20][21][22]. All the ferrocenes that have been linked to the surface of phosphorhydazone dendrimers are functionalized by a phenol, and possibly by another function, in particular a phosphine.…”
