Systematic FTIR and XRD studies unraveled a distinct parity effect related to the packing of NDI molecules with odd or even numbers of methylene groups in the alkyl substituents.

2021年10月1日 · In the present study, vibrational frequencies using FTIR spectroscopy, NMR chemical shifts, optimized molecular structural parameters, HOMO-LUMO analysis, Mullikan atomic charges, MEP, and related molecular properties of NTCDA molecule were studied.

2019年2月15日 · The negation of the decomposition of NTCDA molecular structure during preparation and/or annealing required employing Fourier transformation infrared (FTIR) technique. The topological properties characterization of as-deposited and annealed NTCDA thin films surfaces concluded that the annealing process induced an enhancement in the film smoothness.

Download scientific diagram | FTIR spectra of ITO and ITO/NTCDA. ATR-FTIR was used to obtain the data on the vibrational mode of the films from publication: Optical Characteristics of...

The reaction of Naphthalene 1,4,5,8-dianhydride (NTCDA) with elemental aluminum(0) powder is studied in an aqueous alcoholic KOH mixture to search for the NTCDA anion and dianion...

2010年2月6日 · Notice: Except where noted, spectra from this collection were measured on dispersive instruments, often in carefully selected solvents, and hence may differ in detail from measurements on FTIR instruments or in other chemical environments.

2021年10月1日 · In the present study, vibrational frequencies using FTIR spectroscopy, NMR chemical shifts, optimized molecular structural parameters, HOMO-LUMO analysis, Mullikan atomic charges, MEP, and related molecular properties of NTCDA molecule were studied.

2015年10月30日 · The structure and vibrational properties of the metal–organic interface of 1,4,5,8-naphthalene-tetracarboxylic dianhydride (NTCDA) on Ag (111) were analysed using Fourier-transform infrared absorption spectroscopy in conjunction with density functional theory calculations including dispersion forces (PBE-D3).

Based on the FTIR spectra, we can identify the functional groups produced, at wave numbers 1774 cm -1 (s) and 1302 cm -1 (s) identified as stretching vibrations of closed chain (cyclic) C=O ...

Here, we describe the fabrication of photoactive van der Waals heterojunctions incorporating 1,4,5,8-naphthalene tetracarboxylic dianhydride (NTCDA) and CN. The composite heterojunction systems were characterized by a combination of physical (TEM, SEM, pXRD), spectroscopic (FT-IR, XPS, DRUV, photoluminescence, TCSPC) and kinetic experiments.
