9,10-Anthracenedicarbonitrile may be used as photosensitizer to investigate the photoisomerization of trans-stilbene (TS) in sodium dodecyl sulfate (SDS)/benzyl alcohol (BA)/H2O system.

Definition

ChEBI: An anthracenedinitrile carrying cyano groups at positions 9 and 10.

General Description

9,10-Anthracenedicarbonitrile (DCA, ADC) is an anthracene derivative. Photochemical reactions of DCA in MeCN-MeOH or MeCN-H2O containing hydroxides or methoxides affords 9-methylimino-10-anthracenecarbonitrile. It participates in the generation of nucleophilic α-hydroxymethyl radicals from α-silyl ethers by irradiation. Binding energy of 9,10-anthracenedicarbonitrile adsorbed onto graphene is -1.23eV.

Purification Methods

Recrystallise the dinitrile twice from pyridine [Mattes & Farid J Am Chem Soc 108 7356 1986]. [Beilstein 9 IV 3667.]

Solvent Effects on Photoinduced Electron-Transfer Reactions

Dependence of the fluorescence-quenching rate constant kq, effective quenching distance rq, and free radical yield ΦR on the free enthalphy change ΔGf of full electron transfer has been studied in dichloromethane by using anthracenecarbonitrile as electron-accepting fluorescers and amino- and methoxybenzenes as electron-donating quenchers.On the basis of the present data in dichloromethane and the previous data in acetonitrile, the solvent effects on the electron-transfer fluorescence-quenching mechanism and on the back electron-transfer reaction within the geminate radical ion pairs are elucidated.

Steric Effects in Photoinduced Electron-Transfer Reactions

Quantum yields for formation of separated radical ions are determined for the electron-transfer reactions of singlet excited cyanoanthracene acceptors with sterically hindered alkylbenzene donors, in acetonitrile.These yields are up to 4 times larger than those for unhindered alkylbenzene donors.The yields are controlled by the competition between separation and return electron transfer in the initially formed radical-ion pairs.From studies of the dependence of the steric effect on the driving force for return electron transfer, it is concluded that the main effect of the steric hindrance is to decrease the magnitude of the electronic coupling matrix element for electron transfer, thus decreasing the return electron transfer rate and increasing the separation yield.The sterically hindered donors can be divided into two groups depending upon whether the substituents on the benzene ring have hydrogens that are capable of hyperconjugative stabilization of the positive charge in the radical cation.The electron transfer reorganization parameters are measurably different for the donors that have these substituents compared to those that lack such hydrogen atoms.

A Versatile One-Pot Access to Cyanoarenes from ortho- and para-Quinones: Paving the Way for Cyanated Functional Materials

A generally applicable direct synthesis of cyanoarenes from quinones is presented. Particular emphasis is placed on the preparation of precursors and target molecules relevant for organic materials, including halogenated cyanoarenes and larger cyanated acenes. The reaction and work-up protocols are adjusted for the challenges presented by the different substrates and products. Screening results of the initial reaction optimization are given to further facilitate adaptation to other synthetic problems. The universality of the reaction is finally highlighted by successful substitution of para-quinones by an ortho-quinone as the starting material.
