81-32-3 Usage

General Description

Perylene-3,4,9,10-tetracarboxylic acid is a chemical compound that belongs to the family of perylene dicarboxylic acids. It is a polycyclic aromatic hydrocarbon (PAH) that consists of four carboxylic acid groups attached to a perylene backbone. perylene-3,4,9,10-tetracarboxylic acid is used in various applications, including as a pigment in dyes, in the production of organic semiconductors, and as a fluorescent probe in biomedical research. Perylene-3,4,9,10-tetracarboxylic acid has also shown potential for use in organic photovoltaic devices and organic light-emitting diodes due to its high photoluminescence quantum yield and strong absorption in the visible region of the electromagnetic spectrum. Additionally, it has been studied for its potential as a pollutant and environmental contaminant, with researchers examining its sources, fate, and effects on ecosystems.

Check Digit Verification of cas no

The CAS Registry Mumber 81-32-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81-32:
(4*8)+(3*1)+(2*3)+(1*2)=43
43 % 10 = 3
So 81-32-3 is a valid CAS Registry Number.

The role of reducing agent in perylene tetracarboxylic acid coating on graphene sheets enhances Pd nanoparticles-electrocalytic ethanol oxidation

Li, Shuwen,Yang, Honglei,Dong, Zhengping,Guo, Shujing,Zhao, Jiahui,Gou, Galian,Ren, Ren,Huang, Jingwei,Jin, Jun,Ma, Jiantai

, p. 2303 - 2310 (2013)

New catalysts, consisting of perylene tetracarboxylic acid functionalized graphene sheets support-enhanced electrocatalytic Pd nanoparticles (Pd/PTCA-GS), were fabricated using different reducing agents, including H2, NaBH4 and ethylene glycol (EG). The graphene sheets (GS) were functionalized via π-π stacking and hydrophobic forces. The information of the morphologies, sizes, and dispersion of Pd nanoparticles (NPs) for the as-prepared catalysts was verified by transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), Raman spectra and X-ray diffraction (XRD). As the ethanol electro-oxidation anode catalysts, the new catalysts exhibited better kinetics, higher electrocatalytic activity, better tolerance and better electrochemical stability than the Pd/GS and Pd/C, which illustrated that the new catalysts had potential applications in direct ethanol alkaline fuel cells (DEAFCs). Most attractively, the role of the chemical reduction methods (the NaBH4, EG and H2 as reducing agents) were studied systematically for the ethanol electro-oxidation anode catalysts in DEAFCs. As expected, the chemical reduction method remarkably affected the electrochemical behavior. Among all the Pd/PTCA-GS catalysts tested, Pd/PTCA-GS(NaBH4) exhibited the highest catalytic activity and stability, which may be due to the Pd NPs for Pd/PTCA-GS(NaBH4) having a narrow size distribution, uniform distribution and more perfect crystal structure than that of other as-prepared nanocomposites. These Pd/PTCA-GS are promising catalysts for developing a highly efficient direct ethanol alkaline fuel cells system for power applications. The Royal Society of Chemistry 2013.

Dual-responses for electrochemical and electrochemiluminescent detection based on a bifunctional probe

Han, Jing,Zhuo, Ying,Chai, Yaqin,Yuan, Ruo

, p. 3367 - 3369 (2014)

A bifunctional probe (PTC-Tb) which acts as not only a well-defined and stable electrochemical redox molecule but also as a highly efficient co-reactant of an electrochemiluminescent oxygen-peroxydisulfate system was firstly synthesized and applied to the construction of dual-response aptasensors for thrombin detection.

Guidance from an in situ hot stage in TEM to synthesize magnetic metal nanoparticles from a MOF

Xu, Dan,Zhang, Daliang,Zou, Houbing,Zhu, Liangkui,Xue, Ming,Fang, Qianrong,Qiu, Shilun

, p. 10513 - 10516 (2016)

A series of in situ hot stage experiments using transmission electron microscopy (TEM) were studied to directly observe the transition of a Ni-MOF to Ni nanoparticles wrapped in carbon (Ni-NPC) over temperatures ranging from ambient temperature to 700 °C. Ni-NPC-600 displays high catalytic activity in 4-nitrophenol reduction and high conversion, even after 10 cycles.

New perylene-based non-conventional discotic liquid crystals

Gupta, Satyam Kumar,Setia, Shilpa,Sidiq, Sumyra,Gupta, Monika,Kumar, Sandeep,Pal, Santanu Kumar

, p. 12060 - 12065 (2013)

The synthesis, optical properties and thermal behaviour of three novel non-conventional 3,4,9,10-tetrasubstituted perylene-based discotic oligomers are reported for the first time consisting of a perylene core attached to which are four 4-cyanobiphenyl, triphenylene and cholesteryl units via flexible alkyl spacers. All the oligomers self-assemble into a mesophase and exhibit excellent fluorescence emission properties making them suitable for various opto-electronic applications.

A long-range emissive mega-Stokes inorganic-organic hybrid material with peripheral carboxyl functionality for As(v) recognition and its application in bioimaging

Venkateswarulu,Gambhir, Diksha,Kaur, Harpreet,Daniel, P. Vineeth,Mondal, Prosenjit,Koner, Rik Rani

, p. 13118 - 13125 (2017)

We demonstrate a strategy for the recognition of As5+ in aqueous solution using a red-emissive probe based on a perylene-Cu2+ ensemble decorated with peripheral free carboxyl functionality. Single crystal analysis helped us to understand the chemical structure of the probe. To the best of our knowledge, this is the first probe for arsenic detection which emits in the red region (λem = 600 nm). The perylene-Cu2+ ensemble exhibited a mega-Stokes shift (>100 nm) with a high degree of selectivity upon interaction with As5+, which indicated that the present probe has the potential to be used as a turn-on optical sensor for selective detection of As5+ with fewer experimental limitations. The detection limit was found to be 26 nM. Inspired by its good emissive properties, the ensemble was further explored for imaging As5+ in live cells. Because of its long-range emissive nature, no autofluorescence from the cellular species was observed during the imaging process. The probe was evaluated to be non-toxic and successfully permeated the cell membrane without the help of any permeabilizing agent to image As5+.

Three new heteroatom bay-annulated perylene bisimides (PBIs) have been synthesized by microwave-assisted synthesis in excellent yield. N-annulated and S-annulated perylene bisimides exhibited columnar hexagonal phase, whereas Se-annulated perylene bisimide exhibited low temperature columnar oblique phase in addition to the high temperature columnar hexagonal phase. The cup shaped bay-annulated PBIs pack into columns with enhanced intermolecular interactions. In comparison to PBI, these molecules exhibited lower melting and clearing temperature, with good solubility. A small red shift in the absorption was seen in the case of N-annulated PBI, whereas S- and Se-annulated PBIs exhibited blue-shifted absorption spectra. Bay-annulation increased the HOMO and LUMO levels of the N-annulated perylene bisimide, whereas a slight increase in the LUMO level and a decrease in the HOMO levels were observed in the case of S- and Se-annulated perylene bisimides, in comparison to the simple perylene bisimide. The band gaps of PBI and PBI-N were almost same, whereas an increase in the band gaps were observed in the case of S- and Se-annulated PBIs. The tendency to freeze in the ordered glassy columnar phase for PBI-N and PBI-S will help to overcome the charge traps due to crystallization, which are detrimental to one-dimensional charge carrier mobility. These solution processable electron deficient columnar semiconductors possessing good thermal stability may form an easily accessible promising class of n-type materials.
