Crystal structure and characterization of a novel organic optical crystal: 2-Aminopyridinium trichloroacetate

Growth and characterization of a third order nonlinear optical single crystal: Ethylenediamine-4-nitrophenolate monohydrate

“…Table 5 summarizes the experimental details and results of the Z-scan technique. The nonlinear response (n 2 , b and x (3) ) of EDA4NPH is found to be comparable to piperazinium 4-nitrophenolate monohydrate [16], 2-aminopyridinium trichloroacetate [35] and some metal complexes of thiourea [36,37].…”

Studies on structure, growth and characterization of third order nonlinear optical 2-amino-5-chloropyridinium-4-amino benzoate single crystal

“…Third order nonlinear optical effects require strong delocalization of π-electron conjugation system in organic molecules. The formation of an organic molecule with a proper electron donor and acceptor on either ends of π-electron conjugation system could be a key factor to produce better nonlinear optical responses [4][5][6]. For example, extensive research has been conducted on 4-N,N-dimethylamino-4 -N -methyl-stilbazolium tosylate (DAST) crystals.…”

“…The DAST single crystals were grown in a form of bulk or thin films to be used in nonlinear optical and electrooptic devices for creation and detection of terahertz (THz) frequencies [7,8]. Organic complexes, in which molecules having extremely improved electronic nonlinear optical polarization response possess conjugate systems, show several advantages over inorganic materials [6]. Though a material showing second order nonlinear optical efficiency is very much needed, the requirement of third order molecular crystals and complexes still persists.…”

“…Though a material showing second order nonlinear optical efficiency is very much needed, the requirement of third order molecular crystals and complexes still persists. The extremely strong delocalization of π electrons decides on molecular polarizability and third order molecular polarizability in an organic molecule [6].…”

Density functional theory calculations on conformational, spectroscopic and electrical properties of 3-(2,3-dimethoxyphenyl)-1-(pyridin-2-yl)prop-2-en-1-one: a potential nonlinear optical material

“…It is well known that the delocalized p electrons and the charge transfer between the electron donor and electron acceptor are the main sources of the first hyperpolarizability (b). Organic molecules containing conjugate systems have some advantages over inorganic materials owing to the possibility of highly enhanced electronic NLO polarization responses [2]. It is also known that large hyperpolarizabilities are the result of an optimum combination of various factors such as p delocalization length, donor-acceptor groups, dimensionality and orientation for a given molecular structure.…”
