Second-order non-linear optical response of metallo-organic compounds: towards switchable materials

The interaction between the spin transition and a crystallographic phase transition in the spin-crossover compound [Fe(bbtr)3](ClO4)2: Nucleation, formation of domains and fluctuations

“…They are among the few systems showing bistability at a molecular scale with switchable properties induced by variations of temperature [2,3], pressure [4,5] or by light-irradiation [6]. This makes them interesting for potential application such as high-density information storage systems [7] and displays [8]. By far the largest number of known spin-crossover systems have d 6 iron(II) as central ion, for which the transition occurs between the lowspin (LS) 1 A 1 ðt 6 2g Þ state and the high-spin (HS) 5 T 2 ðt 4 2g e 2 g Þ state.…”

Crystal structure of bis[(2,4-dimethylphenyl)iminomethylpyridine-k2N,N′]-dinitratomercury(II), Hg(C14H14N2)2(NO3)2

“…The metal centers play akey role in enhancing fluorescent emission of the ligands [8]. More classic complexes with functionalized iminopyridines have been reported to exhibit very interesting properties such as spin crossover [9], second order non-linear optical properties [10], or mesogenic behavior [11]. The crystal structure of the title compound …”

Growth and characterization of new nonlinear optical thiourea l-alanine acetate single crystal

“…Second-order NLO materials are much attracted because of their potential applications in the field of optoelectronics [2][3][4][5]. The development of organic NLO materials led to compounds potentially suitable for application in frequency conversion, optical telecommunication, image processing, optical computing, and data storage devices [6][7][8][9].…”
