The electrochemistry, UV-vis spectrophotometry, photoluminescence, and electrogenerated chemiluminescence (ECL) of perylenedicarboxylic imide, perylenetetracarboxylic diimide (PDI), terrylenetetracarboxylic diimide (TDI), and quaterrylenecarboxylic diimide (QDI) were investigated. All compounds undergo two reversible one-electron reductions and one reversible one-electron oxidation reaction. The first reduction potential shifts to less negative values and the potential for oxidation to less positive values for the diimide series with increasing size of the aromatic core. These changes in potential correlate well with orbital energies from molecular orbital calculations. The difference in potential between the first and Second reduction waves decreased with increasing distance between the imide groups, so that TDI and QDI show only a single reduction wave, equivalent to a two- electron reduction. These reduction potentials provide estimates for the equilibrium constant for disproportionation of the radical anion. Very stable ECL spectra of PDI or TDI generated by sequential production of the radical cation and radical anion at an electrode were observed; these were identical to the photoluminescence spectra A consideration of the energetics of the electron transfer reaction and the singlet energy leads to the conclusion that emission occurs mainly via generation of triplets followed by triplet- triplet annihilation (the T-route).

The invention discloses benzoperylene imide derivatives, and a preparation method and application thereof. The structural formula of the benzoperylene imide derivatives is disclosed in the specification. The benzoperylene imide derivatives are prepared by carrying out multiple reactions on the initial raw material 3,4,9,10-perylene tetracarboxylic acid anhydride. The benzoperylene imide derivatives have strong blue light absorptivity, the molar absorption coefficient at the maximum absorption wavelength reaches 50000 molcm above, the benzoperylene imide derivatives have no absorption in other visible light regions within the range of 500-800nm; and the spectrum properties of the derivatives can be utilized to prepare the blue light absorbing material which is applicable to the field of daily high-energy short-wave radiation prevention, such as mobile phone screen anti-blue-light coatings, eyeglass anti-blue-light coatings, paper anti-blue-light painting and the like.
